clutchless gear change

[Slaninar]

You can believe what you want, but its been covered many times, and by many different professional people, not just 'the elders'.
If you slam ot into gear over and over again, of course it'll damage the gearbox, but if you do it properly, it won't do it any harm, even if you do ride on the other side of the road :o

I believe so. I also think that at higher revs, clutchless upshifts are evene less damaging to the clutch plates than shifts using the clutch.
