Clutchless gear shifting?

[Weaver]

I've been told the fastest shift you'll ever do is if you load up the gear lever and wait till the bike hits its rev limiter. It'll slot straight in.
Never tried though

You're well past peak power at the limiter tho (normally)
You can just keep the throttle pinned and use the clutch - the intertia provided by the extra revs will help *acceleration. This is a short-term technique...
*Do Hyosung 250s accelerate?

You can put pressure on the gear lever and it wont change until you momentarily throttle off for each gear change as stated

It will on my bike - the Evo Star shifter shifts when you touch it with your toe.

If you are really bodgy you can hold the pressure on the lever and hold the gas on until it hits the rev limiter and it will slip in smoothly. BUT peak power is usually just a touch below the limiter so you may end up going slower! Also some bikes don't have rev limiters (ouch).

This is my preferred method when drag racing, but I did come LAST at the Nationals, so take it with as many grains of salt as you like ...

I just keep the throttle pinned and it always goes straight in.... thanks mr quick shifter

I dont use clutch for up shift never have.

I just slightly back off and click up easy as that.

I gave this a go last night on the CBR250RR. Works excellent once you get a hang of it, feels like shit when doing it at low rpm's though. Definately much quicker than using a clutch.

Myth PLAUSABLE!!!

I to do it all the time, Track or road. Use the clutch to cahnge down though or things could get ugly.

Must be a definite knack to clutchless downshifting. I can do it ok going up. Not that I usually bother, I am such a nana that using the clutch is ok by me.

Nice mythbusters reference.

Helps to blip the throttle just as with a clutched downshift. Practice makes perfect. It doesn't take long for it to become second-nature.

[Mishy]

man, i can't imagine shifting any other way ! You should do it - It's easy, and fast Big point is this - remember to preload the gearlever BEFORE you blip the throttle closed then open. The gearbox won't shift with the throttle wide open, and as soon as you shut it it'll go right through
Cool huh ?

Forgot to mention, a servicable and well adjusted chain is a must for smooth clutchless downshifts, otherwise there will be too much drivetrain backlash.

Let go? Don't you have an opposable thumb?

Two things here....
1. Yes I do have an opposable thumb......I think....it's the bit next to the big toe, yes?
2. It is at the BACK of the grip.....under full acceleration, the G's backwards are so great that I can't hang on with just the thumb......loosen the fingers and I fall off the back.....quite normal for a V-twin y'know.........

O....K.... this is a piss take right.
You are coming up to a corner and want a smooth entry and you are going to blip the throttle with the bike in gear and the clutch engaged?

Nope. You do it as you go through the gearchange. Takes a bit of practice but once you can it becomes second nature, although I suspect what gearbox ratios you are running can either help or hinder the situation.
I rarely use the clutch in either direction (depending on speed) and after 45,000kms the gearbox changes sweet as ever (bit of a surprise for a Triumph.....).
I cut my teeth (excuse the bad pun) on racecar straight cut "dog" boxes which helped but, like anything else, it's just practice, practice, practice...
