Rieju Marathon 125 SM Pro


The Marathon Supermoto Pro 125 uses the new liquid-cooled 15hp Yamaha 4-stroke 4-valve power source in combination with a lightweight aluminium exhaust silencer for maximum power. The completely new frame ensures perfect weight distribution under all driving conditions. High-end suspension and damping is provided by a 40mm Marzocchi front fork and RIEJU’s own Progressive Racing System at the rear with a gas filled monoshock.

Furthermore, 17″ aluminium rims with sticky street tyres ensure the right grip. The large Galfer Wave disc brakes (300mm front and 200mm rear) in combination with a radially mounted AJP Gold Series double piston calliper provide the necessary deceleration. Steel braided brake lines are standard as are the special graphics on the bodywork, front fork guards, hand guards, digital dashboard, Pro Alloy steering wheel and Domino handles.
