Clutchless Upshifting

Crazy · 07-06-2008, 02:58 PM

How many of you guys do this regularly? I tried it today for the first time, and it seemed pretty smooth (after the first couple which were jerky) but I've heard its bad for your transmission...??

there was a huge thread about this on the previous forum with lots of info posted by otb. Basically, sport bike trannys are just like sequential dogboxes and its not going to hurt them much if at all. i do it regularly, still clutch second though

Crazy · 07-06-2008, 03:08 PM

I was trying it in 3rd gear and up... 1st to 2nd is always too much of a jump.

I searched on the forum and didnt find anything so i thought i'd make a new topic... I don't go to the old place much

i do it regularly. I Pre pressure the shifter then quick short close blip to unload the tranny and youre in.

Dnyce · 07-06-2008, 04:56 PM

yea big long informative thread over there...long story short, do it right, no probs, even on the 1-2 shift. sportbike trannys come with the gears backcut already

DLIT · 07-06-2008, 05:13 PM

It won't hurt it if it's done smoothly. I still clutch it to get to 2nd still. On the street, I use the clutch a lot more because I'm not always high in the revs.

As they've said, no problem if it's done right.

Though, a clutch is cheaper than a transmission....

Shoot, I do it on the Magna if I'm riding somewhat spirited, and that's a cruiser! It's a quick rev-er though. It definitly doesn't seem to mind. Don't try on a Hardely.

I clutch the 1-2 shift though like others have said. I'm not quite good enough to master that one.

yeah supposedly hd's have some very different tranny design

I do it on a Buell. Similar transmission to some HD models. Dog cut gears and beefy internals.

No problems.

3rd or higher, though. Missed gear lower gets damn squirly with high torque.
