Clutchless upshifting

[bromike666]

At my most recent visit to Mr. Codes school I started to practice clutchless upshifting. I've now graduated to full time clutchless upshifting and have no plans for clutchless downshifting. I've heard and read so many differenrt opinions about the pros, cons and dangers but I'd like to get some more feedback.
1. Does it wreck the gears?
2. Should you preload the shifter or not (I've been told it's a big no-no)?
3. I get a slight surge at lower RPM's. Maybe my timing is still off?

What do y'all think?

Clutchless upshifting is cool, downshifting is a bad idea, imho. If its jerky, then you're timing/throttle maintenance is off. Its not easy, but it can be done pretty smoothly. I just switched to a 14t sprocket, and now I have to relearn where to shift and how to add adjust my throttle to smooth it out. Downshifting just seems too abrupt to me, and risks breaking traction.

1. No, you won't wreck the gears if you are matching rpms appropriately. Done well, there is no load on the gear.
2. No, don't preload. That will wear on the synchros in the tranny.
3. Timing might be okay, but you have to drop back on the throttle a bit when you upshift, as the higher gear will not turn the motor as fast if the wheel speed remains the same. Does the surge feel like you are going forward, or slowing down? That will tell you whether you need more throttle or less.

it comes natural when iam going fast i up shift but in every day driving i use the clutch she like to be clutchless when in highspeeds but not slow and downshift w/o clutch no i dont do it to much stress on the trans but when your racing some one is beautiful .

i have i question does jap bike can be clutchless upshift ??? the guy that ride with me all have japs and the see me doing it and tell me that they cant do it sorry is no to treadjack just 1 Q.thanks

Can I show a little ignorance here and ask what exactly is clutchless upshifting? I am assuming it is what it sounds like but are there certain clutches that you can and cannot do this with? I have a Sport 1000 with a dry clutch. Is this OK? What are the benefits?

I'll never know if I don't ask, and who better to ask than the fine people at ducati.ms.

Thanks,
Robbie

Yes, its exactly what it sounds like. Up shifting without using the clutch. Wet clutch, dry clutch, Italian or Japanese...it can be done on any bike. I wouldn't recommend downshifting without the clutch, but upshifting is fine. It takes a little finesse sometimes...you have to know when and how...you have to ease up on the throttle just a bit so as to take the load off the transmission, and just pop it up into the next gear.

I'm getting a little surge forward, guess I need a little less throttle after the blip. Thanks for pointing that out I never thought about the too much/too little question.

Next, I need to master my brake/blip/downshift. Man, thats a tricky one and takes lots of practice. I was using the blip bike at Keith's school but decided to spend more time on track and less on practice bike.

or ... get a PC and fit a quick shifter. Also works better w/ GP shift.

clutchless upshifting is great , i do it on every bike i own and everyone i've ever owned dirt or street , jap or euro its all the same , and i have yet to have a tranny problem . i may tomorrow but , now up to this point .

I agree. Clutchless upshifting can be done without adverse effects as long as you match the RPM's.

I would NEVER EVER downshift without the clutch.



Never....




Ever....

Ummm, Ok. Why not?
I've never had any issues with this on both a wet and dry clutch. It works great for me when I'm on the track.
