Clutchless upshifting - Ducati.ms

swankdaddy7 · Oct 19th, 2011, 1:49 pm

Do many people here do clutchless upshifting? I've been reading about it a little and my friend has been telling me to try it. I have an '09 M1100 dry clutch (he rides a Triumph). Is it any different on Ducati's or on dry clutches? Would it not be recommended for me for any reason? Thanks.

Unless you're racing where fractional seconds count there's no real benefit.

That being said, it's no different on a duc. Give it the beans, lightly pre-load your shifter lever, quickly get off and then back on the throttle and voila, you should now be one gear up.

Important notes are to have enough, but not too much load on the shifter lever and that brief change in throttle.

Too much pressure on the shifter will force a shift while things are under load, or might force an attempt at a shift that goes all to hell. It doesn't take much pressure on the lever at all.

The change in throttle takes some of the load off the system, allowing the gears to change.

no need to preload the shifter; in fact, if you do preload, even the slightest, this load will push the oil out from between the running parts increasing friction.
Accelerate, back off slightly and quickly, bang on the next gear, resume acceleration.
One benefit is less wear on the clutch plates.

I do this when my left hand is tired.

It's not necessary on the street, but the street is a good place to practice it. Whenever I'm getting onto highways (when I can reliably be full throttle through several gears) I'll do it. Or at least try to do it ;-)

you can use the clutch for upshifting, too?

I know right... what is normal to one person is crazy to another... for example... i try to back it in on most turns and put my knee down while giving a thumbs up when riding my Hyper... doesn't everyone?

I usually only clutchless up shift when accelerating pretty hard, like getting on the freeway or some such silliness. Other than that, I use my clutch.

Did it all the time on my S2R800, sometimes not on purpose, justs slipped in so easy it happened - a little pressure and let up on the throttle and you're there. No big deal and effortless.

"and quickly, bang on the next gear"

Banging, stomping, pushing really hard is bad for the shift linkage and shift forks which all equal an expensive trip to the duc-doc. Light preload and slight on/off the throttle. Better to practice at lower RPM's as the gears are not spinning as fast.
You can also down shift with this method as well, lower RPM's also make this easier and less jerky. A slipper clutch makes this a easier proposition.
