690 SMC slipper clutch

the clutch doesn't act like i thought it would. when i hear about slipper clutches i always hear that there is little to no engine braking. it seems like there is a good bit of engine braking with this bike. i have no problem with it, but it's just not what i expected.

The point of a slipper clutch is not to reduce engine braking but to smooth it out by eliminating chatter.

Yea, I don't know if any of the bikes I've ever ridden have had slipper clutches...but to me, the 690 SMC doesn't really seem much different in regards to the clutch/shifting/transmission... Though, the tranny sometimes sounds like I'm shifting a Harley (with a distinctive hard "click" through most upshifts...)

exactly. it doesn't seem any different at all to me from a regular clutch.

I'm so used to giving it a little rev when I downshift that it doesn't really matter to me if it's slipper clutch or not.

Go from 5th to first about 70mph and see what happens when you dump the clutch out. My smc is much smother with the slipper clutch.

I had a STM slipper in my CRF 450 and it feels similar to the SMC. I also had a STM on my last race bike CBR 600RR and it felt much different, way less engine braking. Maybe you don't notice it as much because the supermoto's lighter.

There will be limited benefits during "normal" street riding .

This clutch is very subtle, you dont feel it doing its job, but believe me it is, I rode my old Duke II after 2000 miles on the SMC, then I realized how much it doing, on the Duke the back end was loose all the time but on the smc it keeps the bike inline & lets you set up for the corner in a very controlled way. I think its the nuts...

This to me is a bit extreme, but go from 7,000 rpm in fourth and click it down to second and you'll feel it work!

I think the slipper in my 690 is awesome,i had a worked lc4 for seven years without a slipper clutch and i never got it to slide as smooth as the 690. it works

correct! both of you are right. I think the other people are wanting results from a SC that it just doesnt do. .

i don't want any results. i had just never used a slipper clutch and just expected a lil differently. it's all good though, i like the clutch. i just don't ride crazy enough to fully utilize it, that i know.

I rode a 690 SM last year and I thought the slipper clutch was the coolest thing about the bike. It makes backing it in smoooth and drama free. I wish I had one in all my bikes! :clap:
