slipper clutch

[wardie]

Found on Asphalt Junkies a post on a slipper clutch for the 250's. If you do track days probably a worthy addition. Anyone install the slipper clutch on their 250?

I know the 300's have them.

Found on the Asphalt Junkies websaite a post about slipper clutch mod for th 250 Ninja. Anyone having done this or rode a 250 with a slipper clutch installed?

Almost no need as it hardly has any engine braking to screw with rear traction

Trust me, I am a junkie and have chatted with these riders... Skip it. Unless your top tier racing for points and championships, you don't need it. As a championship winner myself (without a slipper) it wouldn't have made a difference either way. Simple fact when hammering the sh*t outta 2fiddy, if you lock the rear on downshifts, you downshifted too early. Been there, done that.... fun yes, right? Not even close.

Spend your $$$ on other things that will actually get you closer to lap record pace.

Ask me how I know...

Brah....

Never underestimate how badly a rider can charge a corner. hahahaahahhah

For sh*ts and giggles, I will brake super late and downshift waaaayyyy early to get the rear all kinds of out of shape. It aint right, but it sure is fun.

U guys just can't take the fun out of u no how LOL

thanks on slipper clutch info

I'm thinking taking her to Mid Ohio or something for a track day...

Yeah, the only real benefit I could think of is the clutch pull would be easier... if I remember correctly the ninja 250's clutch pull was still very easy though. If you really want to do a cool mod you should consider a EFI install. That's about the only thing I hated about my 250 was those damn carbs!

slipper wouldn't affect clutch pull. 300 has self servo clutch which makes it easier. that's separate from the slipper. 250 lacks good suspension i think

That is only his opinion, not a fact... think of it this way....

IF the slipper clutch was such an ineffective/unneeded mod on the 250, then why the hell did they add one to the 300??

Mainly because a Japanese supplier has come up with a cheap to manufacture clutch, that incorporates both a very easy clutch pull and a reasonably effective slipper function. Ducati paved the way with this design on their lower-end Monsters, and now it's showing up in many Japanese bikes as well.

Based on feedback from racing activities, the Assist & Slipper Clutch uses two types of cams (an assist cam and a slipper cam) to either drive the clutch hub and operating plate together or apart.
Under normal operation, the assist cam functions as a self-servo mechanism, pulling the clutch hub and operating plate together to compress the clutch plates. This allows the total clutch spring load to be reduced, which translates to a lighter clutch lever feel when operating the clutch.
When excessive engine braking occurs – as a result of quick downshifts (or an accidental downshift) – the slipper cam comes into play, forcing the clutch hub and operating plate apart. This relieves pressure on the clutch plates to reduce back-torque and help prevent the rear tyre from hopping and skidding. This race-style function is particularly useful when sport or track riding.

look at the picture... the movement of the outer basket relative to the inner hub moves the servo ramps which when going one way, add pressure to the clutch, but when going the other way (engine braking) actually push the clutch plates apart to make them slip.

a cheaper alternative would be simply using the clutch lever

Because there are enough morons in this world who would rather down shift than learn to use the brakes properly. They believe that the engine is a brake
