I had driven trucks (lorry), for 30 years and have yet to use a clutch...besides first gear take off. My last bike I up, and down shifted without a clutch. Never a problem. Now I surely don't advise doing this without knowing what your doing. That's when things get sideways
I’ve been to La, and the struggle is real…but I would like to introduce to the jury exhibit B, “Houston”. Not very friendly at all. I don’t know what you experience, but my bike had no more problems than any V twin.
