Little point to owning a bike like that if you only ever go to 90mph. Transmissions with correctly calibrated gear ratios to the normal use case are useful things for ICE engines.
The fast ones can which is the only thing that matters in this comparison. Just as there are plenty of slow ICE bikes, but again they aren’t part of this comparison either, this is about 200+MPH bikes like the Lightning LS-218 vs Ducati Panigale R etc.
Hmm. That’s not “the fast ones”, that’s specifically and purposefully built for the purpose of hitting a high speed. Can’t seem to find 0-218 time to see how it would compare with a geared ICE motorcycle. I’m not convinced it’s getting to the top fast enough for gear shifting to matter.
