Only a dirt bike or enduro…
Only a dirt bike or enduro or small road bike would be less than 375 pounds, without any accessories.And the weight of the motorcycle mount would also decrease the payload.My 1983 Honda XL 600r dual purpose bike, made for off road, weighs about 305 pounds, plus a rear rack and weight of motorcycle mount would be close to the weight limit.A newer enduro or dirt bike with electric starter and radiator would be 350 to 400 pounds for a 600 or 650 cc .
