Which clutch is good for tuned supermoto 500?

[johnnytheswede]

Hi guys. I have an almost new clutch in my 500, but it can't hold up when the torque is coming at WOT. That clutch i have now is regular fibre clutch with heavy duty springs. What do you recommend? I was thinking of a barnett carbon fibre kit. Is this the way to go? I will put my recent clutch in one of my other 500's anyway as that engine is standard. Come up with your suggestions boys!

Oh, another iceracing man:=)! So you use that one? Stands up good then?

Now i have changed my clutch that was slipping. The old one looked good and only had about 25 hours on it, but it didn,t hold up so good. Now it was another story! Very satisfyed with the new clutch. I feel that the springs ate tougher and the feeling of the clutch engaging/disengaging is better. The clutch "weighs over" better so i feel the release better. Good stuff so far!

The Barnett Carbon works on N20 bikes, in the dunes. Its pretty friggin' indestructable, but still has a nice feel to it.

Its the only thing I run.

Nice to hear! I'm very satisfyed so far after some riding this week. Grips really good even on tarmac with full throttle shifts:=).

STM for a 02-08 crf450 fits with mods. you need to get the lightest spring which is 30kg

Looks nice! What's the benefit with this clutch compared to a Barnett carbon?

[oldie 30]

it induces the clutch to slip when backpressure builds up, which instead of locking up the wheel still turns

[johnnytheswede]

Ah. ok! Something to think about when it's time for a change next time:=).

Its more of a 4 stroke thing... where theres way more compression braking.

[oldie 30]

Yes to a certain extent, but it can still induce sliding or backing in.
I use a STM which uses a primary spring for clutch pressure and a secondary spring to engage the clutch. This allows you to use any set up you choose. I am cuurently waiting on a 40kg spring and have a 30kg on order. Although the above were part of the reasons for a slipper, I hoped to put less strain on the drive chain as there is no loss of traction on the road.
