No doubt, dirt bikes are long travel suspension, light weight and traverse rugged terrain with ease. Today’s dirt bikes are pretty capable machines, but there are times additional drive from the front wheel would be an advantage. Here in this post, we revealed a front drive system for a KTM 300 EXC that is designed by Marty Lawson and his dad.
With the addition of a front sprocket, the new Hossack style double A-arm front suspension brings anti dive and anti rise capabilities by itself. With a surprisingly simple system, a single universal joint and two chains, they’re powering the front wheel. It adds just 28 pounds, that’s minor weight penalty for a potentially major traction advantage.
There is an overrun ratchet fitted in the front wheel of the bike that allows it to spin faster than the rear wheel in turns. It is full time AWD with adjustable gearing that allows as 1 percent rear wheel slip before the front wheel engages.
