Stoltec Moto has the only drop-in springs for the FZ-09, FJ-09, and XSR900.  We have two sources of supply which and both are manufactured right here in the USA and available in a variety of rates.  These springs are stock replacement and do not require new spring spacers!  Save yourself the hassle of calculating new air volumes and trimming spacers.

2022+ YZF-R7

These springs are the closest thing you have to drop-in at the moment.  You’ll need to shorten the OEM spring spacer by 20 mm, but the spring’s taper maintains the factory geometry to provide perfect seating and rattle-free performance.

Note:  At this time, the lowest rate we offer is a 0.85 kg/mm for this bike.

Contact us for assistance in selecting a spring rate and oil weight.

If you’re only swapping springs at this time, we recommend heavier fork oil found here.
