Mupo Suspension AB1 Evo Factory Rear Shock for Aprilla RSV4 RF / RR 15-20

Performance without Compromise.

After years at the forefront of the most prestigious competitions in the worlds, we dedicated to channel all our know-how in the most technological version of the AB1: the AB1 Evo Factory, in the same specs used by the WSBK Champion Leandro “Tati” Mercado in the 2014 SuperStock 1000 season.

The AB1 Factory is characterised by the Bladder technology inside the reservoir, which significantly increases feel and sensibility and allows continuity and reliability of damping from the first to the last lap.

Completely made of Ergal 7075, aluminium alloy taken for the aerospace industry, the Factory shock integrates lightness, resistance and a high heat coefficient – all contributing to an excellent damping in the most extreme conditions.

The sophisticated hydraulic, tested and approved by riders such as Alex Barros and Michele Pirro, is characterized by a ø 46mm piston CNC machined, which gives more grip and control to the rider in braking, apex and exit of the curve.

Completely adjustable in high and low speed compression, rebound, spring preload and length, the AB1 Factory is the reference point for the rider that wants to find the ideal setting and have a high-performance motorcycle.

To achieve the top performance from your shock, we recommend upgrading to the Hydraulic Preload optional.
