Hello Forum People, Got a quick question. I am wondering what the stiffness and/or spring rate of the different F2-F3-F4-F4i shocks are. I have a 1994 F2 with a 1995 F3 shock, but I am thinking about getting a F4i shock. Hopefully you all can help me out.
Thank you,
Elisha

 

On racetech's website they tell you what the measured spring rates were for a given bike. For some reason they don't list the F4i, but i'm sure that was a mistake on their part, might trying calling them to see if they can give you the stats. Anyhoo, the F3's they measured the rear shock to be 14kg/mm

 

yeah, i looked those up too, and I was surprised by the fact that the F4i was not listed. I was hoping someone had some more information on this.
Thanks for the reply,
Elisha

 

The F4i isn't listed because they are discontinuing the shock springs for the 99 and up F4's.They do list the 99-00 F4 still and it will fit the 01-06 F4i. I just spoke to them yesterday because I was trying to finda 16kg shock spring for my 01 F4i. They couldn't give me an answer as to WHY they are stopping production though. Tucker Rocky doesn't have any more in their warehouse, so you will need to contact Race Tech directly to see what they haveleft. I got lucky and they had the one I needed. It also sucks because I get 30% discount at my local dealer and would have saved $30 bucks if TR had them in stock.
