And power limits.

And bumper height compatibility.

And guardrails that respect motorcyclists body integrity.

So smaller EV batteries and less range and lower price. That seems ok to me. It's possible that advances in batteries will reduce battery weight, so replacing all the guardrails right away may not make sense. Difficult to predict battery future though. Maybe EV's need a cage at the front so the front end doesn't collapse so easily without an engine there?
