Not just for the 1125's, but on any bike what is the advantage of a slipper clutch? I can understand that if you change down too early the engine braking can lock up the rear wheel, and a slipper clutch would stop this by slipping, but is it a real advantage outside of racing? I always blip the throttle as I downshift. On days when I've got it together I can manage to blip and brake at the same time reasonably smoothly... sometimes... Do you still blip the throttle with a slipper clutch, or can you change down and just let the clutch out while braking? cheers, chili | ||

I have a XB9R and a 1125R. On my favorite twisty my rear wheel does not "step out" with the 1125R. On the XB, I need to be aware and mitigate by blipping the throttle or backing off a little on my corner entry. I believe the XB has more compression braking than the 1125R motor and would therefore be more susceptible to unwanted behavior when entering a corner in a spirited manner. Slipper clutch is not only for racing. It comes in handy on public roads as well. | ||

On an I4, the problem is more profound and therefore possibly justifies a slipper clutch. On a V2, not so much. | ||

"It comes in handy on public roads as well." I kinda think that is an understatement. I still blip the throttle somewhat out of habit while down shifting. The slipper clutch works good but it still allows the tire to lock up and skid a little when riding aggressively. So when I`m riding it hard and notice that the tire is dragging I tend to start blipping more. | ||

my zx10r (05) has slipper clutch, they were the first to put it out on a stock bike in 04. Anyway, I still tend to blip out of habit but if I want to, I can go from say 3rd, straight to 1st without worrying about engaging in between and no worry of wheel hop if I were off a bit. I get less engine braking than I was used to on other I4s but it's okay and I could add or remove shims to adjust the level of slip. It is pretty invisible really but between the bike being able to do about 107mph in 1st gear and the slipper clutch, the only way the rear is locking is by brake. | ||

If you are breaking coming into a turn or trail braking through the turn, sometimes it makes it difficult to blip the throttle. In order to be able to rotate the throttle, you need to release the brake which unweights the front suspension. If you still need brake, you'll have to load the suspension up again. The slipper clutch allows you to downshift and brake without blipping. I wish I had one yesterday and the track day. | ||

good for track days, squid gimmick on the street. | ||

Most ride their street bike on track days. I do. It simply removes one more thing a rider has to do to be smooth. If you don't have to blip the throttle, you can concentrate on suspension loading, braking and application of power. | ||

The slipper clutches though on Gixxers,1125R's and the like are not like race set up slipper clutches. I rode a 999 S with a 999 R set up on it and it really would let you do way more if you were to dare that is. Seem's the slipper clutches that are on stock bike are and were designed for the street with the track day from time to time in mind. | ||

my zx10r (05) has slipper clutch, they were the first to put it out on a stock bike in 04. Kawi, has put slipper clutches on bikes since 1991 (aka ZX7R),However they are adjustable, through shims, unlike the newer ball and ramp design by STM. Slipper clutch non the less as long as you knew where to order parts from, and what parts to order R | ||

I guess they are really back-torque limiting clutches. They achieve that by slipping so it is semantics. Anyway interesting to know. I knew that I could adjust the amount of slip on mine through spring like shims but didn't know that about the older ones. Just got back from riding the 10, uly has a flat from yesterday but already had a tire coming that should arrive tomorrow. | ||

My Ducati has one and it makes a he** of a difference when coming into a low speed turn at top speed, you just slam down to first from fourth or fifth gear let go of the clutch and the rear end remains rock solid plus your in the perfect gear coming out of the turn to be at the peak of the power band. One of the best investments I made on the Duc for track and high speed pace riding. They are however very finicky about requiring the perfect stack height of the clutch or else you start to lose gears, especially neutral. | ||

>>but is it a real advantage outside of racing? << Including track days as racing - No. | ||
| Dobr24 |
I have to disagree Dave, any thing you can do to keep traction with your rear wheel while entering any corner is an advantage. | ||
| Danger_dave |
If you are going that hard on the public roads I don't care. | ||

If you are going that hard on the public roads I don't care. Perhaps not. However, I think advancement in safety is worth it. Keep in mind too it is a f**up "forgiver". (Message edited by doerman on August 03, 2008) | ||

You don't have to be going balls out on public roads to see advantage in the slipper. Does one blip the throttle in typical street riding? Why? You are simply doing manually through monitoring engine RPMs what a slipper clutch does automatically. The function is the same. Like I said before, you are simply removing a process from the pilot duty roster making it easier for the rider to concentrate on other things. | ||
| Danger_dave |
Like appropriate speeds? (I just picked up a new Goldwing remember) | ||

I'd take all the slipper I can get running the roads around Suches, GA. Roadways devised by a deviant madman with a paving machine they are. | ||

It's so you can downshift a few gears quickly at once when coming down to speed for the next turn and just let go of the clutch. When you are racing or riding hard you don't want to pull clutch, shift, ease clutch out, repeat, repeat, repeat. Or Pull clutch, bang down a few, then try to get the engine back to the right rpm and the bike to the right speed to get the bike to smoothly settle into the next curve. You just come off the straight, bang it down a few gears, and let go of the clutch without worry about perfectly matching speed to gearing, you can finish that with the brakes I wish I had one on my XB, I've left many black marks when downshifting and "locking" the rear. | ||

Thank you all for your thoughts and experiences. I can see the f**up "forgiver" aspect, probably more relevant to me than anything else  From what's been said it sounds like you could change your riding style quite noticeably with a slipper clutch. I guess mainly a later braking point because there's less things to co-ordinate? Dave, I can see your point. And yes, I meant track days as being closer to racing than street riding. But it sounds like a slipper might help smooth things before you hit *silly* speeds? Found there is a wikipedia page for slipper clutches http://en.wikipedia.org/wiki/Slipper_clutch,http:/ /en.wikipedia.org/wiki/Slipper_clutch I didn't realise they'd been used on race bikes for so long. cheers, chili (Message edited by lemonchili_x1 on August 03, 2008) | ||

Ridden quite a few bikes with them now. I just don't need it on the road. If it's got one it doesn't bother me, whatever, but the only time I ever step the back out is if I mean to. Not on my list of requirements. But then neither is 145 horsepower for the road. | ||
| Glitch |
Suches! Ah the good ol' back yard. I've not ridden a bike with a slipper. I have ridden the roads paved by deviant mad men though. I do hope I'm not missing anything. | ||
| Ft_bstrd |
Yeah - they look almost as good as here. The difference is that here we actually have people driving on them instead of 20 people for the entire island.  | ||

Leave my cousins out of it. | ||
