Does clutchless shifting damage the transmission?

I have been shifting my 954 and even my Dana without using the clutch. After I learned how at the track I use it on the street too.
My friends say I could damage the transmission or at least wear it out sooner.
Does anyone have a scientific explanation of if this is true and why.
It seems to me the were would be negliable with or without a clutch.

Thanks

Re: Does clutchless shifting damage the transmission?

It damages the engaging dogs and it bends the shifting forks. Racers do it but then, they take their trannis apart every year and replace the broken/ bent stuff. Do you?
And it's not quicker.

Use your clutch. It's there for a reason.

Re: Does clutchless shifting damage the transmission?

Two cents+: I've done constant clutchless upshifting, and occasional clutchless downshifting with my 929. I've done it at full throttle, max rpm for more than 65 track days. I do not have any problem whatsoever with the transmission. It still shifts clean and easy. Nothing is bent. Nothing is giving any signs of being worn at all. It still shifts like new, in fact, a little better than when it was new if anything. I still own the bike, and it shifts and runs great.

You must be careful and not force it into the next gear. A little pressure (maybe a few ounces) on the lever to preload, then a quick tiny blip, and it pops into the next gear. If you put a lot of force behind the lever, there is some potential for harm, but if you just preload it, and let it snick in, it should cause no problems. Drag racers do it all the time, because it is quicker. I've done it on every street bike I've had without any transmission problems ever. Air shifters coordinate the movement of the lever with a blip of the throttle, no clutch. Those don't usually cause any transmission problems either. When you do it yourself, you are just doing the same thing as an air shifter.

Re: Does clutchless shifting damage the transmission?

Ive got more than 30,000 on one of my RC51s, plenty of clutchless up and down shifting. Not one single problem ever.

Re: Does clutchless shifting damage the transmission?

I recommend purchasing a power commander with integrated clutchless upshift software/hardware. Superbikes use this technology if I'm not mistaken.

Re: Does clutchless shifting damage the transmission?

Clutchless upshifts = no problem...I use clutch when I downshift...no problem so far.

Clutch is there for a reason, to get in and out of gear, not necessarily between them.

Re: Does clutchless shifting damage the transmission?

I have to disagree.
I haven't used the clutch on my bikes for years on the road or track, up or down the box and haven't had any problems.
Every time you disengage and re-engage the clutch it is slipping causing wear, heat and polluting your oil with clutch material.
Of course, like everything you have to make the effort to learn to do it correctly. Done incorrectly you'll bend forks at the least and possibly wear the dogs. I've got over 60,000kms of road and racing on my SRAD GSXR (bought new) and it stills shifts better than any Honda box I've used.
