I'm about to pick up a new Big Bear, and I found out I can get a deal on a Raptor 80 for my son thrown in as well. I've been talking about getting him started riding for a year now and I'd love to take the opportunity. He's 7 and he's never ridden. Are the speed limiters adequate for a first time rider? I know they have both an intake plate and an adjustable throttle. I'd much rather go with the 80 because it seems to be a better bike all-around and something he can grow with. But I have no experience with the smaller bikes. Any advice would be greatly appreciated!
