Havent heard of any & if they did it would be big bucks. The ones for the IL4's are about $1800.

Doesn't the fuel fed in on the overrun help prevent the same problem as a slipper-clutch?

Or is there no demand because there are none?

A slipper clutch helps when entering corners by not having the rear wheel act as a brake when downshifting.

I could have used one in January's races. Left hand still had stitches and I tried downshifting without clutch in practice and got monster rear wheel hop - so I'd just shift in 3 turns with the clutch and do the rest without

Truthfully, a good, properly adjusted slipper clutch can change the way you race but it'd be a hard sell to say that it'd be worth the $2 grand for street riding.

Folks have been looking - problem is the market is too small and the HD guys are rarely interested in cornering performance - I doubt that somebody making a Buell slipper clutch could sell 6 a year and then he'd be on the phone daily trying to explain slipper clutch adjustment to the squids who didn't need one to begin with.

Becides that the slipper clutchs that are on all race bikes are Dry clutchs.Which Buells are bathed in Primary Fluid for the tranny.

slipper clutch is for when you downshift into turn it avoids wheel hop from compression of the engine and the light load on the rear wheel while braking hard for a turn. in any case unless your racing save the doe and just blip your throttle and get engine up to speed of the gear you are dwnshifting to.

Awww geez Ron - I didn't want it taken that way!

I just bet that if you did produce one, you'd have a string of never-ending phone conversations with people trying to get them setup and end up the subject of "threads of hate" on sportbike boards. ; )

What for? I don't believe XB produces enough power needed for slipper clutch.

Power has nothing to do with a slipper clutch. It's engine braking. And Buell motors do quite a job of slowing the back tire when you downshift a couple gears and drop the clutch. Not only does it make the back squirm, but it'll over rev the motor. Rev limiters don't work when the wheel is driving the motor.

Becides that the slipper clutchs that are on all race bikes are Dry clutchs.Which Buells are bathed in Primary Fluid for the tranny.

Actually there are several slipper clutches that dont have to be dry, for example the Kawi ZX7 has always(well since 91) come with a slipper clutch only they call it a back torque limiter, not sure on Aprilla, i know Ducati is Dry, but the Evo model for the GSXR is wet, its more the mechanics of it, and not the clutch itself, very cool, but i belive its over kill on the street
However i THOUGHT i saw one, i remeber it being very expensive due to the backing plate that was fabed to retain the trans fluid, but for the life of me i can find it, maybe it was just an experiment or prototype
Will keep looking

Sure they do! When the pistons start using the intake valves as a "jake brake", the "rev limiter" is engaged!

Would even the racers spend over $1000 for a slipper clutch? Maybe 3-4 of the "factory" guys, but if I remember right the old AMA Pro Thunder bike HAD a slipper clutch. So, they spent the time & cash to get one. Would the "average" Buell racer sink that much cash into a slipper clutch? Is it worth more than 2 sets of race tires? Would it change podium positions & be worth more contingency?

g, keep looking please

people spend thousands on bling, so why not performance

i would love to be hauling a$$ upto the corner and just be able to slam it down to the gear i want and drop the clutch without wheel slide or chatter and stress on the motor, and then just power out

even all the dirt bike racers are useing them, it can make your lap times faster

it makes you smoother

some might think its cheating because it takes some of the work(skill)out of downshifting correctly

but i think it would be perfect for a squid like me

later, ron

On hard braking, the rear wheel is almost off the ground - Drop a gear and let the clutch out and she'll really hop if rou aren't rpm matching very well (easy to happen - especially in traffic starting at about 135, finishing about 100 a second later on turn-in

As it is, I tend to select a gear, downshift, get it engaged well ahead of the apex - I could possibly grab a lower gear for more pull coming out of the turn - but think this would maybe only work for one or 2 turns

I'm with ya squid, err Ron. I think it'd be a great idea for the factory to consider putting slippers on future bikes. And we might all agree the tranny could use a little more refinement. Even a 6th gear but that may be stretching for now.

why would someone even consider downshifting multiple times, then dumping the clutch while healed over in a turn? that sounds utterly idiotic. anybody doing that on the street needs more than a slipper clutch to straighten their ride out.

Water cooling jackets for the motor. Reading all the other threads, this would be THE ticket to high performance!
