The best and easiest front end conversion I did to my Maico was from '87 cr 250, I just had to get the standard clamps enlarged 1/2 mm and everything just slotted straight in. They are different fork to the 125, and give a far better ride. Traditional KYB's on the 125, showa cartridge on 250/500, just make sure you get 86/87 versions, the 88's where shit.
