Clutchless Upshifting

Amber Lamps · 07-07-2008, 09:08 PM

Either this thread has been done before or it was on one of the other forums... Now I know that Rossi ,Pedrosa,et al are gods but whenever you see camera shots of their hands,they always clutch when they shift. Plus,I still don't understand why you wouldn't want to use the clutch. I mean if you have to roll off the throttle anyway,what do you gain? Please explain...

Ha I was right ! This same discussion is going on on TWO other forums I belong to! That's interesting.....kinda....

They clutch when downshifting, not upshifting though.

Hmmm... you're probably right. I bet they have ignition kill tech on their bikes for sure.

They do. The quick-shifter is trickle-down tech from them.

Could be. Forgot about the drag racers. I know that the old moto gp guys were using clutchless upshifts long before the quick-shifter. I just assumed that somebody with money got smart and made it happen.

yea pretty much

i'd say drag racing started it with the air shifter, cuz a drag bike has room for the tank and hoses and stuff, more so than a gp bike

and from that, along with all the electronic age of the 80's-most bikes had point ignitions up until 80 or 81 i believe-circuit racing produced the quickshifter.

I clutchless upshift every gear on the track including the 1-2 shift except for a couple places (like coming over the top of the hill in 5)

On the street I clutch more often unless I'm riding twisties, then it's mostly clutchless there too.
