Has anyone done this? What are your opinions on it?

Thanks

they do this to harley's with built motors. it allows for more surface area contact, therefor reducing the clutch slippage

[INFAMOUSRACER7]

just put a crf clutch in it

Is the judder spring the only difference between the trx and the crf clutch?

[JH Racing]

yes minus the judder springs a CRF and TRX have the same clutch plates,inner basket, and pressure plate.

[mc_racer]

Does that mean that I can use a rekluse pro from a CRF in my TRX as long as I use a TRX basket?

YEAH YOU CAN RUN A CRF REKLUSE WITHOUT ANY PROBLEM...BUT FOR OUR REACE BIKE WE RUN STOCK CRF CLUTCH'S AND HAVE HAD GREAT LUCK...ALSO SPARKS CLUTCH KIT WORKS GOOD.

i run this mod on my drag bike with trx250r hd springs and it really works well. i do however get some clutch slippage after about 5 passes at the hill...

I did this mod two years ago. The clutch now feels like it has less slip and less chatter. It also feel like it has a more positive engagement.

I did this mod with the crf clutches about a week ago. Before this mod my stock oem clutch plates lasted about 3 months. This will last longer.

I looked this up again to remind myself about the nature of friction and contact area. The basic caluclation for friction does change purely as a function of surface area. Increasing pressure or making the clutch plates rough will give more results than widening the friction disk which spins against a very smooth surface. These aren't rubber tires against rough asphalt. The material of that unique disk might be different. (?) Other than the disk material, stiffer springs are probably the best bang for buck.
