Clutchless shifting?

Ideal for when you have a pillion on the back. Helps reduce the chance of an odd helmet bang.

helps if the pillion is holding the tank... mainly works under braking then, but i'd imagine it would have to be a pretty bad shift otherwise.

it verys when i use the clutch... ask any motorcrosser and they will tell you how they use the clutch not just for changing gears... you can also incorperate this into your riding... but don't try learn it all at once or youll have more than a buggered gearbox to worry about, i do clutch my katana though being an older bike, newer bikes it's not so much of an issue.

So you're advising him to learn how to mx style fan the clutch? What a wanker. Do NOT clutchless downshift, Wren

Maybe you should train or masturbate less, then.

Generally if you listen to decent riders riding they slip the clutch to change and just hold the throttle open, you don't have time (or money) for balancing the revs to make a nice clutchless upshift

Like discotex, the only reason you would really worry about clutchless shifting is to stop overrev at the track. Have you ever rode really hard to around redline and pulled in the clutch to change? Sounds pretty gay, not to mention revving the shit out of it
Unless your bike's got a slipper clutch I wouldn't clutchless down shift either. That is unless you like momentary lockups at highspeed, but that's what your right foot is for!

Probably both, well definetly train more anyway. Who said anything bout matching revs, I just throttle off and bang it through, 2T so bugger all rotating mass/engine braking, know plenty of others who do this on 4Ts as well.

yeh, I have noticed that on my roadbike, and thats just a 250 @ 10k, I imagine the effect would be somewhat magnified on bigger bikes at the track.

Do that on the 1st to 2nd change on the R6 and you will be left sitting on the road wondering where your bike went...

Sorry if I didn't make it clear, but I was talking about MX riding

Yes they do. Saves rolling off throttle. Did you think I was talking road racing?

**SMOKEU** · 25th October 2009, 20:07

The gearbox would wear out a lot quicker if the clutch isn't used to upshift wouldn't it?

Depends on how you do it. Smooth shifts with no preloading should be fine.

**Sidewinder** · 25th October 2009, 20:15

well theres only one way, you shift with out using the clutch duh

Still don't agree with ya.

I don't know your background, but from my time in MX every average or better rider just held the throttle open and slipped the clutch each time they tapped the shifter up with their foot.

Look. Arguably a "good rider" and if you can see his clutch fingers in the first 20 seconds or so, and aren't deaf, you can clearly hear it overrev between shifts and see his fingers slip the clutch

For road riding purposes I'll clutch 1st to 2nd and often go clutchless from there up. I back off the throttle slightly when shifting and whack it back open after gear changes. Technically there's nothing to stop you downshift too using this method but I don't really see a need to chop down fast enough to warrant a clutchless downshift

My trumpet does zero to a hundy in 30 seconds.Clutchless gear change could save me a second of my life that I could use later.
I use my clutch on the track up shifting aswell.Its done with a different hand from everything else so im not convinced the gearchange takes longer.
