Clutchless upshifting

i thought this was seriously advised against, unless you have a slipper clutch? as then you can end up locking the rear wheel, as you are whacking it in at higher revs compared to what it was just at, and you need to rev the engine a lot to compensate or the engine braking will just make the rear break traction - and what happens if the engine simply doesnt rev high enough to compensate?

i dunno, maybe it is suitable for experienced riders to do clutchless downshifts without a slipper clutch, but i've never heard of it!

I used to do it on my CG125 all the time. Took a bit to learn, but once done, I forgot the thing had a cluch (except stopping).

I'd never dream of doing it on the SV though. Far too worried about your exact comments! I also have a certain respect for tarmac.

ok a message to the wise sage's on this thread. You may or may not have noticed that one or two people with more limited biking experience are looking at this thread?

Therefore why not explain the "obvious" advantages of upshifting without use of the clutch.


And why down shifting without the clutch is beneficial or advantageous.

I've found that

I get a smoother change by not using the clutch, also the change takes less time to complete.

As for why. I havent got a clue. But its definately smoother without the clutch.

The clutch, as I'm sure you know, doesn't directly act upon the gearbox at all, it interrupts the drive between the crankshaft and the gearbox. As you have undoubtedly noticed if you try and change under power, (or under deceleration), the gearbox has load on it and the lever is impossible to move, you can unload the gearbox by disconnecting the drive from it - pulling the clutch lever - or you can do it by a neutral throttle position, it's identical to the 'box which won't care at all.
When you consider some of the scrappy amatuerish changes I've made with the clutch, I imagine most of your clutchless changes have got to better!
Also the common question of difficult gearchanges is ever present on the SV forum, and many people - myself included - ordinarily answer that the first thing that should be done is clutch adjustment - if the clutch is not cleanly disconnecting the drive to the 'box then there will still be some load on it, and the gearchange will be hard if not impossible.
A neat, non damaging gearchange is made by removing as much of the load from the gearbox parts as is possible- whatever method you use, with practice you can change down clutchlessly too, although I don't recommend making a habit of it - it's much harder than going up, and the only time you need it is when you break a clutch cable a grillion miles from home.

Technical term that, grillion!

Grillion (adj) - A distance that is *just* too far to push your bike, and equally distant from a phone to call the breakdown people.

need to be very apt at finding netural though would you not. would be more handy to know how to clutchless down shift if you only had one arm

I use clutchless shifts in the car whenever Iam pootling along in traffic.
(Poor mans automatic)

Slowly getting the hang of clutchless up shifts on the SV.
Somehow it seems much harder to match the engine and box speeds, I end up with a little upward pressure on the lever and gradually let the road speed drop until it clicks in.

While I am so clumsy at it I would be much quicker using the clutch.
More practice required I guess.

Clutchless downshifts - ummm thats a challange. -- that can wait.
