Cheers for that Beenz. More armour should I get into a warranty dispute about a blown gearbox :D

TSM, cheers for the kind thought :) I've had the back step out on me before (as many folks know) and it's not nice when you're not expecting it, but it can also be useful when you deliberately cause it.

Anyhow, I shall tread carefully, there's 2 things I'm not fond of the taste of. Hospital food, and tarmac.

I never use the clutch going up the box (ok the exception being if I'm carrying pillion), I even (stupidly) very often clutchless up shift right leant over coming off islands, but then thats just the way I've been riding for years and I'm so used to it now :oops: i have done the odd clutchless down shift but its usually when my hands are so cold I can't move my fingers, but IMO its simply too dangerous and will b*gger the bike before long. My gearbox is absolutely fine, but then it just comes down being smooth with the gear changes. At the end of the day its like anything, thrash or abuse it and it will die prematurely but treat it gently and keep it maintained and it will last a lifetime.

I hardly ever use the the clutch to go up the box, very rarely change down without it though... The clutch helps the timing of the down shift. I tried once on the Falco and it protested, with a large black line up the Uxbridge Road :lol:

I find that clutchless up changes, when you get the hang of them can add to the smoothness of your riding. Although, I must add, going for 1st to 2nd without the aid of a clutch is a precision manoeuvre...

It'll probably differ from bike to bike due to wear & tear, but I find that changing around about the 12mph mark seems nice. Not sure of the rev's, only saw it once on the way in this morning, wasn't really looking at the dial/lcd.

Carlos, I'm glad I'm not the only one that changes without a clutch mid corner. Sometimes it just feels natural.

Yep, i tried on a TL at about 30 and it nearly pulled a wheelie, then it kept sputtering for a few seconds after. So i did not try again for my saftey.

If you do it right this change can be smoother than a cashmere codpiece, what you're looking for is for there to be no 'jerk' in the drive, bit of practice though and anyone can do it, the trick, (if there is one), is to only drop the throttle out to the point at which you would need it to be so that in the next gear you would neither be accelerating or decelerating from the speed at which you initiated the change, thus allows all the bits and pieces to be revolving at as near the same speed as possible thus they mesh together as imperceptibly as possible.
Downside: None, if you get it right, which isn't hard. Won't win you any drag races though.
I do this quite often, exactly how he says, it is beautifully smooth, if not, don't do it. Absolutely lazy change! :)

there is no advantage to clutchless shifting on the street

if it's smoother for you, then you need more practice with the clutch

However, there is an advantage to be profficient at clutchless shifting both up AND down
that way when your clutch cable snaps or your hydraulic system fails, yer not stranded

clutchless downshifting works just as smooth as clutchless upshifting, load the shifter, blip the throttle, doesn't hurt the tranny anymore than clutchless upshifting

But how do you pull off in the first place without pulling the mother of all wheelies :shock:

I disagree with that. The actual act of changing gear isn't the advantage I saw. I was using the brakes less than usual, because I was letting the engine do the work. Typically, I'd be going around a corner a gear lower than I usually do.

Because I was on the brakes less, I was carrying more (percieved at least) corner speed. I was also revving higher exiting the corner, which obviously left me in a better place for accelleration. Yes I could probably do that and use the clutch, but that's not how it happened this morning.

how does clutchless shifting have anything to do with brake usage :?:
