Most motorcycle problems are caused by the nut that connects the handlebars to the saddle.

Clutchless Upshifting

Post by Pugzilla on Fri 15 May 2015, 10:09 pm

Do many of you do clutchless gear changes on your CB500?

Thinking about learning how to do it.

I do quite often on the upshifts once out of 1st. Never quite got the hang going down though.

clutchless upshifts are fine after being out of 1st gear, just knock the throttle off a little when you change up, then back on the gas. dont clutchless shift though when going down the gears.

I'm with ashcroc and Tricky. Upshifts, but not down, and preferably the higher gears. Once you get the hang of it, it's actually quite easy.

And remember; your rear wheel contains an internal shock absorber designed for just this purpose. Klonk!

I asked this question a few months ago maybe? Do a search you might find the thread Smile

I've been doing clutchless upshifts for miles and miles. Put 120,000 on my last CB doing that and never had gearbox problems. But only when making moderate to quick progress through the gears, not when bumbling around town. 1st to 2nd is actually fine as well as long as you're not hesitant; knowing neutral is in between makes it a bit scary, and I only reserve it for the quickest of take-offs, but it's fine.

I've recently got the knack of clutchless downshifts too. It's tricky going down from third or lower, but from sixth, fifth and fourth it works beautifully. Just a little blip of the revs needed as you do it, and a decisive left foot.

Yep, absolutley. I agree on all counts.

Oh yes. Much fun it is too.
As above I've done 1st to 2nd a couple of times too but I don't make a habit of it. 2nd and up, yes if I'm being 'assertive' with acceleration.

I haven't quite got the hang of it on full power screaming overtakes though.

When you start working on that, look out for false neutrals! Done a few of those and it scares the sh*t out of not only me, but also the cagers I'm overtaking at that moment Smile

Good to hear positive things about clutchless upshifting. Was trying it out today for the first time. I heard it saves the clutch but was afraid this may be at the expense of the gearbox. But since reading through this thread I no longer have any fears.

Have a look at this video anyone who is interested. I had a bit of a look into it and this was the only technical explanation i could find other than "been doing it for years and the bike is still fine."

Everything he says seems logical and mechanically sound.

Nice one liverpoool_f_,
 
Makes a lot of sense and scientific too boot. I think I'll avoid clutchless shifts since I am more of a casual/cruising rider and don't need super fast gear changes.
 
And just to prove you can find anything on the internet to support your opinion, here is the next video that autoplayed on youtube...
 
"How Clutchless Shifting Works on a Motorcycle and Why it doesn't damage a gearbox"

A bit less scientific, in my opinion.

Cheers for bringing this up.
I have always done it myself.
Again not when bumbling along.
I forgot i did it. It is good fun though.
I used to wonder if it was doing any damage and then I completely forgot about wondering about it.
So thanks. Smile

But yes, I found a false neutral myself for the first time the other week, surprised the 'life' out of me.
