Are the frame, forks, swinging arm, shock, wheels, brakes, steering geometry and wheel base the same on these bikes?
Frame is different to take the bigger engine, swinging arm is the same, rear wheel hub is wider by around 5mm on the 250/310, shock has a longer resivoir on the 250/310 but is the same over all length, and I dont have a clue on the geometry And thats about all I have measured / swapped over between the two, Im sure others will know more.
Thanks, I read a review, clearly wrong, in a mag that said the frame was the same.....what do you prefer, the WR125 or the 4 stroke?
