What is a slipper clutch?

#1 Unread post by < I Fly > »

Well... more accurately how does it work?
The R1 special edition and Gixxer have them but I don't know how they stop the clutch from grabbing (that's what they do right?).

here...
Slipper clutches are specialized clutches developed for racing motorcycles to eliminate the effects of engine braking when riders would decelerate as they entered corners. They are designed to disengage or "slip" when the rear wheel tries to drive the engine faster than it would normally. The engine braking forces in conventional clutches will normally be transmitted back along the drive chain causing the rear wheel to hop, chatter or lose traction. Slipper clutches eliminate this extra loading on the rear suspension giving riders a more predictable ride and eliminate the risk of over-revving the engine during downshifts.

Wouldn't that lead to some bad habits like... downshifting during curves?

Two things I thought you weren't supposed to do: shift during a curve and brake during a curve.

that's true for the basics.

skills like trail braking and shifting mid-turn are advance skills.

Slipper clutches seem totally unnecessary for the road as they encourage bad riding habits and give the rider a false sense of security by making them rely on the bike to do something simple for them. Bye bye throttle & clutch control.

During the MSF one of the tests we were required to complete during our final exam was to make a wide turn (half circle) about 10 meters in diameter. during which we must shift up once into second, then back down into first, exit the pylons (spaced 1/2 yard apart) turn around, re-enter the curve shift up into second, then down into first and finally come to a complete stop, all without putting down a foot.
Of course I'm generalizing from a single example here, but everyone does that. At least I do.

I would find that last part very difficult, the stopping without putting a foot down.

yeah it's harder on top heavy bikes.

i can only stop for less than a sec before i have to put my foot down.

i think on bikes w/ a lower CoG, you can stop for a few secs before you have to put your foot down.

haha, well obviously you're allowed to put a foot down when you stop. But from start to finish you cannot put a foot down. How does that sound?
