yeah, that s what they did, that was before the quads can, sticking to what dirt bikers do they started racing them and just kept owning themselves, so they banned them from racing and honda stopped making them, i think suzuki and yami did that too, then either suzuki or kawasaki made the first quad, ive still got a trike from 1976- honda atc 90, still goes hard.
Trikes were originally farm bikes, they were indestructable, but had no suspension, just massive soft tires, so they floated on water!! dad's got soo many funny stories, one time they road it threoug a river a few time, sorry not through it, floated on it!
