I have a Ktech RazorR Shock it has about 2500mi on it 2 of it trackdays. It has the heavy spring. For the FZ09 you won’t find a better Shock. I sold the FZ for a 17 ZX6R so building it for track rite now. Sent from my iPhone using Tapatalk
It is adjustable from stock and I believe +3 -3 are the distances. I can try to double check on that. Im not on here much you can email me [email protected] for any more questions.
