First of all i really like the model, but you should put the front axle up higher, in real life the upper end of the front tires is about level with the bottom part of hood. I also taught that the radius of the rear wheels i a bit too big. in real life it uses the same tires as the Magnum 7240 that is in the Vanilla game, i put these tires on it by myself and the MX looks way more realistic that way.
I also would love to see mudguards in the Front and a front linkage.
