so the slipper clutch. is this a needed for race only thing. seems to make sense. does it help with sport riding?? | ||
| Hammer71 |
Great item to have, would be greater if there was one for the Buell. | ||
| Josh_cox |
There is one for Buell  . I can get them for you from Buell Racing. It will help get rid of the back wheel chattering and sliding into the corners when you are really hammering it. Retail on the clutch is $1200 and the adjustment tool for it is $85. I need to check at work tomorrow on the exact price due to it being a race item, but I think I can give the normal 10% BadWeb discount. Josh jcox@cycleconnectionh-d.com | ||

Great item, especially for a twin with a lot of engine braking. Then you don't have to worry so much about matching RPM to the tranny when you downshift. You can concentrate on your brakes and turn in instead. Getting to be more common on stock bikes every year. | ||

Josh, I stand corrected. Forgot that the XBrr stuff was available. Bit out of my budget so I'll just keep trying to match speed and shifts the best I can. | ||

I'd put in a slipper clutch before I'd do major engine work! ANYTHING that helps handling, braking, turning confidence will go a much farther toward making you "fast" than will adding brute power. | ||

Amen slaughter. | ||

The slipper clutch is also available direct from STM, who manufacture it for the XBRR. Can't remember the exact price but it is similar. A slipper clutch is actually of less use on the road than on the track, unless you really feel the need to be able to bang down 3 or 4 gears going into a corner and not lock the rear wheel. If you do then I don't think you'll be racking up any big mileages  | ||

The clutch is manufactured by STM as Matt mentioned. Here are the prices I can do for you on the whole setup: Slipper Clutch $1250 retail $1125 BadWeb Alto Clutch Plates $132.00 retail $118.80 BadWeb Clutch adjuster tool $99.00 retail $89.10 BadWeb If you switch to a slipper, you need to run Redline ATF in the primary also. | ||

Just up shift as you get chatter! Problem solved 1,200 dollars in pocket | ||

Ouch. I'll have to stick with blipping my throttle. Thanks though. | ||

Mike, I would like to see you doing some hot laps on pavement, ..... fast laps.... so when your setting up/diving into a corner really hot, hard on the brakes, at the limits of adhesion and feathering out the clutch on downshifts, got your line all picked out - rumble strip to rumble strip, trailbraking or not, and hoping it doesn't happen again.....the rear wheel starts hopping and skidding all over the place. upshift. then come tell me about how that helped. I may not be doing too many things well on a track, but it took a little while to figure out that it wasn't my trailbraking, and it took a little while to get comfortable with the fact that it was going to happen again and again. Getting through one tight corner balancing everything just right to avoid the wheel hop only meant that you had to learn to balance it all for the other 3 or 4 tight ones just right all within four or five sessions of a track day without doing relatively too much damage to your bike before picking it up to try again.....with more clutch, less clutch, braking earlier, not downshifting until you've scrubbed off more speed, et., etc..... I can provide you with a bike that (under me) NEEDS a slipper. Or......I've got it......going around the track slower.......yeah that would work too! problem solved, 1200 dollars in pocket! engine braking is cool for pulling down high chair coasters....oh wait you don't do that either. we need to get you on the asphalt. Next time you come over to work on your barstool I'll tell you all about my worst trackday ever.....not my first. There were some members of this board, that were at said trackday that may have noticed my frustration, and frequent agricultural work, and although I said it was my worst day at the track, I'll also tell you it was the funnest day I've ever spent on a motorcycle. The challenges of a new track coupled with the above mentioned challenges of the big motor, and having the goofiest bunch of competitive clowns ever assembled in one place.....priceless flame disclaimer, I don't claim to be any kind of anything, other than an addicted enthusiast on the track. YMMV  | ||

Mike, Asphalt much different then the dirt!!! | ||

Sam, When are we going to do Heartland Park this year?  | ||

Interesting discussion. I've never seen or used a slipper clutch. With a slipper clutch, if you're rolling at mid to high RPM and roll off the throttle, do you still get the engine braking you would get with a standard clutch or something near to it? I'm sort of wondering if a slipper clutch like free wheels on over run. Jack | ||
| Mortarmanmike120 |
Would somebody please just explain what a slipper clutch does, it's operation, and why it's an advantage. Thanks in advance. | ||

It allows for the clutch to slip under hard deccel so that the rear tire does not slide out from under the rider when entering a corner hot. With all of the engine braking that these bikes have it is very difficult to keep the bike upright if you are downshifting entering a corner. With the slipper clutch this problem is gone. It would be similar to when your clutch is going out on your car or bike and it slips under hard accel, except working under deccel. So when you downshift the bike it is not necessary to blip the throttle to bring up rpms to match the speed of the bike. The clutch will control that for you without launching you over the handlebars. Good enough? (Message edited by Olinxb12r on February 07, 2007) | ||

There are some miconceptions with slipper clutches, the most common is that they will remedy bad gear changing and bad riding technique, which they won't What they will do is limit engine braking by working on a ramp and bearing system. When the wheel speed is much higher than the engine speed the clutch will disengage and slip to allow the bike to almost freewheel until the engine/wheel speed catch up. This means that you are able to change down 2 or 3 gears going into a corner without the rear wheel locking up. Most of the 'decent' slipper clutches on the market (STM,Sigma etc) are adjustable so that you can set your own limit for when they start to work. One downside is that bump starting a bike or trying to start a bike on rollers can be difficult if the clutch is not set up right. For road use they really are little more than a fashion accessory, particularly on the high revving jap multis that don't suffer the same heavy engine braking that twins suffer from, and most road riders won't get the full benefit from using one. On the track however a slipper clutch is now considered almost obligatory and will reduce lap times by around the same amount as using a quickshifter setup. | ||

Thanks Olin and Trojan. Interesting. | ||

Matt, thanx for being so..... um diplomatic my problems on the track were intermitant and unpredictable as I didn't know what exactly was going on....and my use of engine braking had never before been problematic.....lesson learned. | ||

I reckon you need to be a very 'enthusiastic' rider to get any significant value out of a slipper clutch on the road. The track is another matter. I had a slipper clutch on my 748r last season and it was a pleasure and I reckon my XB9r would benefit from a slipper. I think it also depends on your riding technique. Younger riders tend to use the brakes better than us older guys who rely more on engine braking and therefore find a slipper of greater benefit. I find that a slipper clutch lets you arrive at the turn in point with the bike more settled. All the drama associated with a sliding and skipping back wheel makes smooth cornering more difficult and a slipper can eliminate that drama. I certainly wouldn't spend 1200 bucks on a slipper if I was only using the bike on the road. My opinion for what it's worth. | ||

I rode a gsxr600 with one and found it to be a; getting use too; thangy. I have to became intimate with my brakes before I try to use one in a track situation. Anyway, if im going to the track im borrowing or buying a inline 4. unless its a kart track then ill giver a try. | ||
| Xl1200r |
Having never used one, I won't comment on how much of a help they may or may not be. I will say that getting a perfect mesh on the revs when downshifting is one of the most satisfying things to do when riding. I practice heel/toe shifting in my car everytime I drive just because it's so gratifying. | ||

I need the secondary spring for the XBRR STM Slipper Clutch...waiting on the Italians (STM is an italian company) ain't cuttin it. Any know of one available? |
