Does any one know if a frc rear clutch is 107mm or 109 mm

107

thanks a lot. Does any body recommend a certain one. We got a polaris 90 with hetrick pipe and malaossi front clutch. Runs really good right now, but clutch shoes are a little worn and we would like a good backup at least. I really don't know how often we should replace the rear. Any info let me know.

Dr. Pulley rear. It comes complete, bell and all.

I may be wrong but, I think the FRC rear clutches are 109.

We've always ran the Malossi non adj. rear clutch and the Koso bell with out any trouble for three years.

I also have a Koso used rear clutch like new for sale with all Koso 1500 springs in it.

how often to replace will depend on amount of use and type of use , once a year works for us . The Dr Pulley "rear" seems to be the most hot set-up for most of the racers , we have got very good feedback.

Etondaddy, do you still have that koso clutch. If so give me a price. Thanks Joe

Another question for you guys. What size torsion spring do you recommend for a 82lb. rider. Thanks Joe

i prefer the dr pulley clutch setup , we have used many different setups and this works for us , take all the advice you can most everything works if setup correctly.

we stock and run the Koso fully adjustable with great results, they are very easy to dial in to bike specific needs with the springs and weights and have a nice long lasting pad surface that hooks up good. If interested PM me for more info.

For your tosion spring question that is really based on your engine configuration, rider style, and a few other specifics, but I would recommend the 1500 ZTR. rear torsion spring then dial in the rest with the roller weights.

I'll take $160.00 plus shipping..... there's only one race on the clutch and about six on the bell. The front clutch's is not included. I'll take $60.00 for the front clutch. That's 50% off retail......
