Shift w/o Clutch

When I was riding yesterday, I realized I was able to upshift from 5 to 6 without clutch. As I wasn't sure why, I didn't experiment more... Is it because:
1. That was the intended behavior? If so, when can I shift without clutch?
2. It can work, but not good for the bike, and can (but haven't yet) lead to things break?
3. Something broke already?

Can someone let me know which one it is?

Thanks.

Re: Shift w/o Clutch

You can shift any manual without a clutch. It is called rev matching.

Confuses vag for cock... That would be "cock" as in rooster. Which might be even worse. And takes more duct tape to avoid a damn mess. Has lead to interesting nights.

Re: Shift w/o Clutch

Search "clutchless upshifting" and you'll see some long running threads on this subject.

Yes it's fine. No it won't hurt the bike. Just be sure to do it right, if there's a load on the transmission, don't try to force a shift... let up on the throttle as you would normally do, and kick it up.

I only use my clutch to engage 1st gear from a stop, shift to 2nd and to downshift.

I'm clueless but just started clutchless upshifts on track. I like it, big kick in the arse on a 1000cc bike. Ain't tried it on my SRAD.

Re: Shift w/o Clutch

I do it every once in a while when I'm riding. It's very simple. Let of throttle just a tiny bit while putting a little pressure on the shifter, and it slides right in smooth and effortlessly.

A member here who is wiser than me suggested that preloading the shifter is a bad idea. Can damage (hope I get this right) the shift forks or dogs, I forget which he said.

shift forks. You can damage them if you apply insane amount of the pressure on the gear lever.

Yeah, that makes sense. When I said to put a little pressure on the shifter, I didn't mean to pull hard on it, just a very slight amount to take up the tiny amount of slack so when you let off the throttle it slides in. You certainly don't want to force it, it should be smooth and if you encounter resistance, stop.

Just making sure, clutchless DOWNshift is not recommended?

Re: Shift w/o Clutch

I've done clutchless downshifting and it seems fine. The method I did was, Let off the throttle a tiny bit and at the same time shift but what I notice is that if you downshift w/o the clutch from 2nd to 1st, it doesn't always go into 1st. It tends to stick in neutral and even when you use the clutch to get it out neutral it will grind the gears going into 1st. So I don't really use clutchless downshift. I do shift up w/o the clutch. It should be the same method. Let off the throttle a bit and at the same time shift. I also notice from 1st to 2nd it sometimes jerks a little bit but if done right, it does shifts smooth.

Re: Shift w/o Clutch

Yes - clutchless upshifting can be done without hurting anything if done properly.

No - there is absolutely no reason to do it on the street other than pure laziness.

Yes - the best way to do it is to get a Quickshifter (if you are racing).
