Question for you 07 and 08 owners

[Vtec44]

Supposedly, Honda has a neat trick to mimic slipper clutch without the additional cost and weight. Have you tried it on your bike?

[Chas4RR]

lol - don't know if I've tried it "intentionally".

Its not an engine saver for over-revs like a true slipper, but I think its designed just to take the lash out of less than perfect downshifts by varying intake air via a servo controlled butterfly valve. I will say that high rpm quick downshifts on this bike have yet to produce rear stepping out moments, but I try to match rev downshift as much as possible anyways. hope that helps.

[Vtec44]

Yeah, I wonder how is it compare to a standard slipper clutch. I prefer to rev-match while downshifting, but what Honda has to offer is intriguing (if it's close to how a slipper clutch works).

All I know is I accidently slammed down to 2nd gear in Pahrump on Turn 8. I was going about 80 mph and I just heard a really loud whirling noise. The rear moved slightly but other than that, nothing else. So I think my slipper worked.

[quietlilsis]

what's the trick?

[Vtec44]

What Chaz said...

Just downshift it without rev match and see if the butterfly valve on your bike helps eliminate rear wheel spins

[Asian Dave]

Buy an R6 or GSXR.

[Vtec44]

R6's now come with slipper clutch? Wow, I didn't know that. Not that I need to use it, with a lot of practice I can downshift and rev match 3 times in a role now.

[Asian Dave]

Both did, starting in 06. Not sure on the Kawai's. I think the Gixxar's are better though. Cam said when he slammed down gears on his bike, there's a huge clanking sound. He said it scared the crap outta him the first time he used it.

[Vtec44]

I know the 6RR had it way before everyone else in 03. Master Yoda on Sportbikers.Net has one.

[Chas4RR]

Ive seen a bunch of posts on guys putting true slipper clutches in 07's...but its a track thing to keep from popping a motor on high-rev downshifts. Most have said the IACV (Intake Air Control Valve) does about 30% of what a slipper clutch does. They other function of the IACV is to smooth out the transition from no throttle to throttle on response. I would say it does both things really well.

[quietlilsis]

oh that... yeah, i had noticed very smooth down-shifts without needing to do much in the way of rev matching.

even mentioned it to a friend a couple weeks ago. :udontsay

Buy an R6 or GSXR.


Lol but then I would have to bail off this forum, which I just signed up for, get a new login name create a new password and profile. Screw it I am just gonna rev match.:thumb

As mentioned, Honda engineered the IACV to function in place of a slipper clutch. Also, as mentioned it does not have the same results as a slipper. The IACV does an outstanding job of smoothing out less than perfect downshifts, although you still need to atempt decent downshifts... it isn't a miricale worker. The transition from off throttle to on throttle is also smoothed out by this device, and reduces the lash. The throttle is very stiff on the 07/08 600rr, so this is a welcomed addition.

I have had no issues with my bike, and have not once wished for a slipper clutch. I can click off fairly high rpm downshifts in the rain with out any wheel lockup, so something must be doing its job.

[Cyanide41]

I am not used to slipper clutches so when I was on an 07 I didn't try to ride like I had one. I did notice that when cracking open the throttle the bike didn't seem that smooth. I HEAR a PCIII will fix that.

[bredebee]

I'm awesome it's a given I can do it



AHAHAHAHAHAHAHHAHAHAA
