The FZ-07’s fork springs are designed for a rider weighing about 190-210 lbs in gear on the road. If you’re outside that weight range or ride aggressively on the street or track, a different spring rate is likely in order. Manufactured by Sonic Springs right here in the USA and available in a variety of rates.
You’ll need to use the included plastic tubing to make new spacers Simply add 5 mm of length as compared to the stock spacer and you’re all set. If you’re ordering a heavier spring than 0.90 kg/mm, we highly recommend 15 wt fork oil.
