Thread drift. I used to bounce of the rev limiter on my Bassa quite often. Yet I seldom do riding my Breva 1100. I was thinking at first it was because the Breva is somewhat quicker than the Bassa, but then I recalled I was often riding with Sergio DeSouza while on the Bassa, and he moved to Brazil just before I got the Breva! Anyone who rode with Sergio, may recall what I'm talking about!
