The second bike I got for wifey here was a '85 Honda V65 Magna. She really learned the art of throttle control and respect with that one. So I think your wife should be able to pick a 500 off the stand and go on down the road. Only 6 hp difference from a 350 if I remember correctly. Will.
(I was kidding up there...)So if the 350 and 500 are so close, why do the 350's sell so much in India? Cheaper? Less cost for insurance?
