There are Four Options all of which are 80's. The Beta, Clipic, Gas Gas Rookie and Sherco. The Clipic, Beta and Gas Gas are purpose built to be 80's using a small frame with Full size wheels. The Sherco uses a full size frame. The Engine in the Beta is probably the best although the Clipic is pretty good. The Gas Gas seems to have suffered from a lack of development but the entry of Gas Gas into the 50 market has bucked them up a bit. The Sherco is good for the bigger rider but the "feel" of the thing is a bit "big" for young riders. What it comes down to is how many are out there. On this the Beta has it. Plenty out there and the early ones should be good on price. They do take a hammering however so take a good look at them before buying.
