Spring 2020 Status

There’s no beating around the bush:  things are weird right now.  Everywhere.  The other night I was thinking about our state of affairs:  if I entered a coma four years ago and woke up today, I wouldn’t believe my eyes.  Things are a little scary, but the good news is that we’re all going through this together and we’ll get through it together.  Besides, we always have motorcycles, even if we end up riding less this spring…

In response to this developing situation, Stoltec Moto is taking preventative measures to ensure the health and safety of our customers and our team.  As such, effective immediately and until further notice:

  1. All ride-in services and installation work is postponed.
  2. Mail-order services (such as fork and shock work) will continue.
  3. We will only be shipping USPS.
  4. You may experience delays in order fulfillment.  While we keep ample stock in many components, we rely on a complex supply chain.  We cannot predict how our suppliers will be affected, so please, bear with us.  If an order is placed that we cannot fill (or don’t know when it will be filled, we will be in touch.  Right now, none of our suppliers are shut down…but that could change at a moment’s notice.
  5. Our team is healthy and will continue to employ industry-accepted best practices with respect to hand washing and hygiene.  In short, we won’t compromise the safety of what’s inside your box.

Lastly, we ultimately expect a downturn in business during Q2 and Q3 this year.  We can (and will) weather this storm.  However, we are hereby cancelling the in-house Tenere 700 project.  Between the uncertain times we’re living through and the botched roll-out on Yamaha’s part, it is simply not a prudent investment of our time and resources.  To all of those who have been in touch, we sincerely appreciate your support and interest.  Naturally, we will support the community as best we can!

In the meantime, stay safe and healthy.  Don’t fall victim to the public hysteria, but please prepare for the next several months.  In the least, we’ll all have time to spend with our loved ones as work and school closures slow our daily lives.  Provided we all remain healthy, how can more time ever be a bad thing?

Ride safe!

Riding for Flow in 2019

It’s easy to get lost in spec sheets, counting miles, or tracking lap times.  Fun, for sure, but not what really makes us tick.  The Hungarian psychologist Mihaly Csikszentmihalyi spent his life understanding flow, how it’s achieved, and why it’s a necessary component of a fulfilling life.  Spend time studying his work, however, and you’ll realize that many live without experiencing it.  What is it and why is it so elusive?  You’re going to need some two wheel therapy to figure this out.

Mother Nature answered your call with crystal clear skies, fair temperatures, and a propensity to ad lib.  The effervescence of late spring transports your soul, each smell conjuring some long-forgotten familiarity.  Lush, vibrant forests give way to fields of floral-spotted wild grass in full bloom.  Meandering waterways abut rolling hills populated only by those sporting four legs or wings.  This rapid-fire immersion in nature’s innocence was enabled by shaking things up – a healthy dose of cognitive dissonance. The stage has been set.

An unfamiliar road opens up, and it’s yours.  Tempting as it is to turn it into your personal race track, you yield.  You’re not carving pristine tarmac.  The road has substance – character, gravitas, history.  Every bump, crack, and imperfection conveys a song.  As with the best performers, the road’s account is dynamic, adapting to the audience all the while retaining a personality.  Listen to the story.  Feel the song.

Shaking things up is good, but not when it comes to your equipment.  Ironically, these rides demand a splash of instinctive routine.  The well set up bike disappears under your control – perfect lever reach, a sorted suspension, intuitive braking, and the seat you forgot about.  Downshifts are coupled with the perfect metering of throttle.  The thrum of the engine is felt but never fatigues.  The exhaust announces your intentions but never incriminates.  The melding of rider and machine is symbiotic, culminating in a dance to the road’s song.  Dance.

Eventualities arrive and the song ends, the dance slows to a stop, and reality returns from the periphery.  These moments don’t arise often, and frankly, that’s by nature’s design.  Their spontaneity increases the allure of happenstance and rewards flexibility.  Moments of flow may be fleeting, but they bind us together like a cosmic superglue.  How will you find your flow this year? Leave a comment and share your flow.

‘Unliking’ Facebook | Stoltec Moto

Some customers have noticed our sudden disappearance from Facebook.  No, we’re not going out of business!  What gives?

The move appears to be sudden because we didn’t advertise this.  But, it’s a been a process that has taken over one month to complete.  Frankly, it’s been a long time coming.

Spoiler alert:  we’re not a fan of Facebook.  For years, we avoided the social media platform for a plethora of reasons.  We only created a social media presence a few years ago in an attempt to better connect with the loads of customers who use Facebook as their primary means of communications.  We were skeptical it’d magically provide boatloads of new customers, but hey, we’re about experimentation and trying new things.

We never realized those ‘boatloads’ of new customers.  Was our skepticism warranted?  Maybe.  We are blessed to have a solid following of customers, and most continued to email, call, or contact us on various forums.  It’s worth mentioning that we didn’t go ‘all in’ on Facebook, so it’s likely a harder push would have yielded more traffic.  The marketing numbers are out there and Facebook continues to be a solid performer.

So why did we leave?  Well, at the expense of sounding like a broken record, we just simply don’t support the social media giant’s business practices.  There’s no shortage of bad press for Facebook these days, and many of us saw this coming.  As motorcyclists, we’re all sensitive to distracted driving, whatever the cause.  But we’ve encountered more and more people who are seemingly ‘plugged in’ all the time…not just behind the wheel.  Like any new technology, we’re still not sure how this will play out in the end – whenever that is.  How are our social lives being affected?  Are we more disconnected now that we’re all uber-connected?  How are our families and children being affected? How are our societies as-a-whole being affected?

Stoltec Moto doesn’t employ any psychologists or sociologists, so we’re not qualified to answer those questions.  However, we ARE motorcyclists, and one thing motorcyclists rely on (to some extent) is FEEL.  And the bottom line for us is that something just doesn’t FEEL right.  Whatever it is.  So until we figure that out, you won’t find us on Facebook.  As always, you can contact us here.

15+ R1 Radial Master Cyl Retrofit on FZ-10

Happy Friday, everyone:

That’s right…the 2015-2016 R1 Nissan 16 mm radial master cylinder works with the line kit. Making a minor adjustment to the top line with a new fitting and a different hose length. But much to my surprise, we were able to re-use the line! Pretty cool considering that you can upgrade the lines now and retrofit the radial m/c down the road when funds exist. No need to buy a new line and remove anything under the tank!


How about that switch? Well, good news again: it fits! Still waiting on a lever to be 100% sure everything aligns and functions properly, but it looks like we’re a go.

Here’s a view from the cockpit showing the line and harness. The switch is oriented 90 degrees from it’s factory location, so the harness loses some slack. However, there is enough before the wire clamp that you can redistribute the wiring a bit. No binding from lock to lock.

Again, this brake line here has a different m/c fitting and line length up top, so the production kits are going to look a little better up top!

FZ-10: How do we slow this thing down?

Site has been quiet, but there has been plenty of action to report out on. Took some time off with the family to hang out at the Jersey shore for a week (no, Snookie wasn’t there), so that delayed this progress report. But without further ado:

Stainless Steel Brake Lines
No pictures to show and tell quite yet – still tweaking a couple fittings and hose lengths/routes. What we hope to be the final prototype should be here by Friday. But, what I’ll say:

  1. Stock lines are a mix of hard steel lines and soft rubber lines. We’re going to replace the hard lines throughout. A bit of work up front, but a cleaner install in the end. Plus, it’ll save the customer money.
  2. Stock lines have 6 flare fittings due to the hard lines. We were able to cut the final count in half down to 3. Fewer potential leak points are a good thing – and these are readily accessible instead of buried under the tank!
  3. Net weight savings are in the 1.2-1.3 lb range. Not bad for just a line swap!

Pictures to follow during the next progress report – but we’re getting very close to being done. Oh, and a friendly public service announcement – if/when you do this swap, do yourself a favor and just remove the radiator. It isn’t that much work, and you’ll thank me later. Those radiator fins are the most delicate I’ve laid my hands on. Good Lord…

Version 2 of the rear shock should be back by the end of the week. We may need to make another final tweak to the layout because the R1 has more tool access around the shock (the FZ-10’s passenger pegs are closer to the shock than on the R1). The bike has been down in pieces for the better part of 3 weeks while we sort some things out, so regrettably, no ride reports – yet. Stay tuned.

Stator Cover

As you may recall from an earlier post in this thread, the FZ-10 has a larger flywheel and a different stator than the R1. As such, the FZ-10 requires a taller stator cover. So unfortunately, this necessitates a new design. Unless of course you’re man enough to retrofit the R1’s stator and flywheel – I’m quietly trying to talk myself out of ruining the FZ by trying this…

Turns out that adding a perimeter spacer to raise the cover or adding more material to cover will price this thing WAY out of the market. Therefore, Eric @ Woodcraft and I have been going back and forth on the right path forward. Right now, we’re looking at this:

Although it’s not as bullet proof as the R1’s billet aluminum cover, there are some positives to this. First, it’s going to cost much less money. Like, a lot less. Second, installation won’t require removing the stator cover. Third, repairing crash damage won’t require removing the stator cover. Not that removing the cover is a particularly difficult task, but why sign up for more work that is necessary.

We utilized a similar design on the FZ-09 – and yes, we’ve crash tested it. It worked flawlessly.


Here is an overlay of Woodcraft’s current R1 rearset on the FZ-10:

As you can see, the FZ’s foot pegs are lower – much lower than the R1’s aftermarket kit. About 2″ lower and 5/8″ back in the [U]lowest position[/U]. In my opinion, this is going to be too aggressive the typical FZ-10 owner. The comfort of the bike is a major appeal, so detracting from that would seem to be a major misstep. Correct me if you disagree.

That said, this is the current design:

It’s hard to tell what changed based on that view alone, but the new low position is about .75″ higher and .625″ back when compared to stock. As of today, the pegs can be adjusted 1.5″ higher (from the low position) to answer your canyon carving or track day needs.

We’re working on getting some parts printed within the next couple weeks so we can see how it all feels. My gut says 0.75″ higher in the lowest position will be OK on this bike since there is a lot of leg room. For fear of completely sidetracking this thread, I’ve created a new thread dedicated to the rearsets – feel free to weigh in here: Woodcraft Rear Sets – Your Opinion is Needed!

FZ-10 Crash Protection Development

Did some parts bin jockeying last week with some of Woodcraft’s goodies.. First order of business was to try out the R1’s axle sliders. Figured it was an easy swap considering the R1 and FZ-10 use the same axles. Success!



As you can see, the standard spools are also a direct fit (no surprises there).

Tried to assemble the standard R1 frame sliders, but the pucks interfered with the bodywork. However, the standard puck we used on the FZ-09 and FZ-07 works perfectly. Working with Woodcraft to pull a part number and get some kits boxed up and ready to go.

Next up was to try the R1’s engine covers…


The other side wasn’t so fortunate…

Didn’t grab a shot to show it (SORRY!), but the R1 cover is about 13 mm too shallow. Apparently, the extra flywheel mass we kept reading about was added onto the actual flywheel. Surprising or not, this necessitated a deeper cover. Working with Eric Wood at Woodcraft to figure out a work-around. Have two good options on the table to make this happen pretty quickly, so stayed tuned.

Except for the LH stator cover, things never go this easily. Thank God Yamaha really did just convert an R1 for us. Makes our jobs easier!

As we get part numbers pulled, we’ll add these parts to our web store. Stay tuned to the forum for a group buy or two to kick things off.

On another side note, tried to install the Yoshimura FZ-09 fender eliminator. It looked sooo close. I’m told that close only matters in horseshoes and hand grenades. A shame, because the Yosh kit is really quite top notch. Great light, adjustable signal mounts (and removable!), and perfect fitment. I spoke with Yosh last week and they should have something soon. If that doesn’t work out, Stoltec will make one.

FZ-10 Stock Shock Technical Review

The jury has deliberated and the verdict is in on the shock. Meh. In fairness, it’s leaps and bounds beyond that of the ‘lesser’ FZ’s. By a long shot. But that shouldn’t be a surprise to anyone who hasn’t been living under a rock for the past three years.

First, the shock is identical externally to the R1 with one exception: The R1 has ride height adjustment while the FZ-10 does not. Despite what we’ve read in the press, the FZ-10 shock has the same spring according to our measurements. Both bikes use a spring that spec’d out at ~475-480 lb/in. Makes you wonder what they were thinking since the FZ has a heavier steel subframe, factory option luggage, and a greater probability of a pillion rider. Really – have you seen the R1’s seat? I’d rather walk.

Our prototype shock is being built next week, and we’ll start testing with a 550 lb/in spring rate for a 195 lb geared rider. Pro racers typically run 600-650 depending on the circuit and track conditions, so that should give you some perspective on how poorly sprung the bike is. So I’ll reiterate: if you weigh more than about 150 lbs in gear, the stock spring is too soft. And really, that weight is being generous. The pain you’re feeling on large bumps is the bike plowing into the bump stop as it bottoms out. A heavier spring will fix this issue.

The damping is another matter altogether. Penske ran the shock on the dyno yesterday for us.

The results are interesting. Well, maybe not since the performance is identical to the R1. But either way, there are some points that are worth mentioning. We’ve found a lot of people ‘feel’ something makes a difference, but the data doesn’t always support it. The placebo effect is real. Let this be our guide.

There’s a lot of stuff to make you cross-eyed here, so bear with me. I’ve left the image at full resolution and quality, so feel free to click on the image to zoom in.

  1. The range of adjustment is shown in the top/center. This highlights the range of adjustment you get and full open, full hard, and mid point on compression and rebound.
  2. The graph immediate to the left (still on top) is our spec for the FZ-09. This shock dyno curve was chosen to highlight a known ‘good’. Plus, the spring rate that shock was valved for is very similar to our target for an average weight FZ-10 rider.
  3. The next row down shows runs to highlight the variance that each adjustment affords. Low speed compression on left, rebound on right.
  4. The bottom three graphs show the high speed compression test. On the left, rebound was full soft, LSC was full hard. In center, both rebound and LSC were full hard. On right, both rebound and LSC were full soft.

Great. Translation?

  1. First, take notice of the rebound test plot on the center right. For those who are unfamiliar with these graphs, the positive sloping lines are compression and the negative sloping lines are rebound. Since the rebound adjustment was varied with run (4 click increase per run), you’d expect to see some increase in rebound damping on those negatively sloped lines. However, you’ll also notice that the compression curves varied as well. Why? Simple. The jet in the main piston effectively increases compression damping when rebound is increased. Conversely, compression damping is reduced as rebound is reduced. It’s important to note that the rebound adjuster’s effect on compression damping is actually greater than the LSC adjuster. It’s hard to explain without showing the internals, but take my word for it. The numbers don’t lie.
  2. Note the HSC runs across the bottom. You’ll see that the individual runs overlap on each sheet (six runs in total). This is because the HSC adjuster doesn’t actually do anything in the speed ranges we’re able to measure (10 in/s is pretty fast). As mentioned above, the rebound and LSC adjustments have a larger effect.
  3. Now, divert your gaze from the shape of the curves to the actual values at various shaft speeds. You’ll notice that the overall range of adjustment is limited and the magnitude is substantially less than the FZ-09 control shock.

Blah, blah, blah…are we done here? The take away is this:

Spring – too soft for most riders.
Rebound – sufficient range, but tied to the compression circuit.
High speed compression – minimal/no effect.
Low speed compression – works, but is overshadowed by the rebound adjustment.

Re-springing and revalving isn’t out of the question, but we’re still limited by the design of this shock. The relationship between rebound and compression won’t go away without substantial modifications.

FZ-10 Deconstruction | Stoltec Moto

It’s about that time: deconstruction. What better way to ‘use’ a new 800-mile old bike? Take it apart.

First order of business is to get the shock down to Penske for a dyno baseline. It arrived there last Friday, so hopefully have some data back this week.

Not much to report on yet, but for those who embark on this project, I recommend removing the rear wheel to gain extra clearance. I was surprised to see they kept the hollow bolts from the R1.

While we were back on the swingarm, figured it was a good time to verify fitment of the Pitbull Trailer Restraint system. Given the age of the bike, Pitbull didn’t have fitment information on the bike. Based on what we know, including the fiche, took a gamble on the R1 pins. Perfect fit. JB-R and JB-L.

If you trailer your bike to the track and haven’t heard of this kit, do yourself a favor and check it out. Your life will improve for the better. You’ll never wonder if your bike fell over inside the trailer or if the straps on your open trailer loosened up in the rain. Your looks will improve, you’ll make more friends, and your dog’s farts will stop stinking. Winning all around!

Since the rear suspension, or lack thereof, prevented the bike from being ridden, it seemed like a good time to address the other deficient area of the bike: brakes!

Complete removal of the lines – rubber and hard.

Typical of all ABS bikes with the servo under the seat, there are a lot of lines and joints. The plan is to eliminate the hard lines completely unless an insurmountable challenge presents itself. Reduced number of leak points, easier installation (once you remove the hard lines – the flare fittings can be hard to get at), and less weight.

Unfortunately, getting the lines off, requires removal of the airbox and lowering of the radiator (though no coolant was drained). The worst part was getting those damn scoops off. I’m a little disappointed in how fiddly these bits are. I though this level of bastard was reserved for, and monopolized by, Triumph. Live and learn. Here’s a few shots of the bikes innards for the curious amongst the audience.

If anyone has any questions for requests for pictures/information while it’s apart, PM me. I’ll do my best to accommodate.
