Several years ago, Surflex discontinued the production of centrifugal clutches for Puch Maxi E50 engines. This left numerous Maxi riders facing an issue with worn-out clutches, as the quality of aftermarket clutches was subpar. A compatible replacement clutch shoe, breathing new life into the worn Surflex clutches, emerged as the solution. After initial testing and multiple upgrades, it became evident that the Aramid replacement clutch shoe is excellently suited for both the original everyday engine and tuned motors.
What started as a small initiative evolved into A.S.P. - All Supreme Parts. In addition to clutches, you now also find a straight-cut racing gearbox along with all its associated components. Quality remains the top priority.
