Shifted like a quickshift at full throttle

So on my ride yesterday, at WOT, I put pressure on the shifter just before rev-limiter and it just clicked right into gear, no clutch, this was 2nd into 3rd I believe. I only did it once because I don't know what damage I may cause the engine, but wow what a boost in speed not having to pull the clutch and then let it out again! I was almost startled at what a difference it made! I may have to put a quickshift on my list o doodads for my bike!

Hopefully tranny is ok, my bike shifts up and down so easy it's almost an automatic! A little pressure and a slight squeeze of the clutch and it shifts, up or down. I have even had it downshift on my as I was decelerating just by putting a small amount of pressure on the lever. Sometimes, I can give it a small quick rev and I can downshift without the clutch, totally smoothly. Upshifting without a clutch is beyond simple, but I try not to do up or down without the clutch because I don't want to hurt it.

 

Will not hurt the clutch. Just like a quick shifter. Blipping the throttle releases load on the trans allowing you to upshift.

 

This is a pretty common method of shifting, I've never done it by bouncing off the rev limiter but I frequently shift sans clutch by lifting off the throttle momentarily. It's also an easy way to check for the elusive 7th gear. You'll find people who claim it does damage, but on a simple dog clutch transmission as long as you don't put too much force on the shifting forks and your shifts are quick and complete you shouldn't be able to do much harm.

 

I've been shifting all my bikes clutch less for years without issue. That includes 1983 GPz 750, 1986 Ninja 900, 2000 ZX12R, 2002 SV650, 2001 CBR1100XX and my recently acquired 2009 VFR800. I was riding the SV650 on the track, without the clutch while racing. All you have to know is when to blip the throttle, on the up or downshift. All I can say is that it is a lot more fun to ride a motorbike this way. Sounds especially cool on the downshifts.

Totally agree with flymyassoff. I nearly always upshift without the clutch, easy to do just takes a bit of practice. Downshifting needs lots more, usually coasting at low revs and it snicks in. Not too much pressure on lever though.

 

Racing I used to only use the clutch from first to second and down shifts. On the street, I always use the clutch, its a light touch as the shift lever is loaded by my boot pressure. Never used gp shift pattern either on my race bikes.

On a down shift you could brake, pull the clutch in and click a bunch of down shifts and let the clutch oot in the proper rpm/proper gear/speed. Two stroke riders used this method mostly. They gave you a clutch for a reason you know.

 

Downshifting without the clutch is more fun, requires rev matching. I'll do it on occasion if coming up on a corner too quick.

 

Reason being, one cannot rev match

Seriously, rev matching is very easy to do with a little bit of practise...

Clutch less downshifts? Yikes!
I always sync' blipping the throttle, working the clutch and timing the shifts to get good engine braking without that horrible 'hitting a brick wall with revs screaming and rear wheel locking up' .
I sometimes engage the clutch slowly into say 2nd so it acts like a slipper clutch. Something that racing taught me as my humble Hornet didn't have a slipper.

 

Only time I use clutch on way up is to slip into second when at low revs and do same as mark641 on down shift with a blip of throttle and clutch when changing gear to get smooth engine braking. Done it with all 3 VFR's I have owned and didn't hurt them a bit.

I've accidentally slipped it into a lower gear at lower RPMs just by having pressure on the shifter, but I use the blip ah JD clutch. Even the Ducati and BMW raise the revs before shipping it into the lower gear with their auto blip shifters.
