Video: Aaron Plessinger on the 450

250 supercross and motocross champ this season, Aaron Plessinger is already getting the laps in on the factory 450 Yamaha.

It is widely believed Plessinger will be even better on a 450 given his size and technique, but with an 18 round supercross championship and longer races, Plessinger will still have a lot of adjustments even if he appears to be able to adapt to the bike easily.
