You didn't mention as to how old your son is.Best bet would be if you're fortunate enough to have someone that rents Harleys in your area, then take him there so he can test drive different models and decide for himself. If they don't have that big of a selection to choose from, then go to your local H-D Dealer and they may have some "Demos" you can test drive.I'm more than sure you already know these H-D's aren't cheap by no means, so test driving to decide which model ya like and can handle ,before ya put down that cash will be the smart move. Good Luck !!!! Ride safe, Hi-Tek Rednek:42:
