When I look at the bike in the first picture that Firko posted , with the BSA motor , I have one question : Why ?
The only answer I can think of is : Because he could .
And Big K , with regards to the Maico / Husky 510 hybrid , it is argueably the best evo frame with the best evo 4 stroke motor . You would think that that would be a pretty good combination & would even be legal by our evo class rules . Some would say that the '78/9 Maico Magnum frame handles better than the '81 Maico. The Husky 510 in original form is a pretty good package , but just doesn't have the sharp turning ability of the Maico & isn't as neutral feeling when in the air off jumps (in my opinion) .
