Mupo AB1 290mm Shock Absorber | Fully adjustable performance suspension for pit bikes

The Mupo AB1 mono-shock absorber was specially developed for sporty use on the racetrack and for ambitious recreational riders. Thanks to its high-quality oleo-pneumatic construction, precise CNC manufacturing, and extensive adjustment options, it offers maximum control, consistent performance, and high thermal stability – even under extreme loads.

The thin-walled steel cylinder features a special coating that minimizes friction and optimizes heat exchange. The CNC-machined Anticorodal piston, with a diameter of 46 mm, is hard-anodized (50 µm) and equipped with a special D.U. guide band to ensure sensitive response and a long service life.

The separate reservoir, made of Ergal (Ø 50 mm), is internally lapped and black anodized. This functional anodization was deliberately chosen because it allows for better heat dissipation than other color variants, thus ensuring consistent damping performance. The 16 mm piston rod, as well as the CNC-milled, hard-anodized heads and mounts made of Ergal, underscore the uncompromising commitment to quality.
