Im sorry but if a person can’t start on a 600 they are retarded.
My first bike was a brand new 08 r6. Picked it up and drove it home. First bike I ever owned. No motorcycle class either. I know I’m not the best rider, but I never gift anyone, myself, had an accident.
Seriously if you don’t have enough self respect or discipline for a 600 you got no business on any bike wether 50cc or 1000cc.
If he bought it cause its cheap and good on gas, fine cool. Otherwise its for chicks 100%.
