Continental Contitech Scooter XT Premium CVT Drive Belt size 788-17-28 commonly found on 50cc 2-stroke full-size street scooters and ATVs with the 1PE40QMB Minarelli engine.

Continental went back to the drawing board for the Conti Scooter XT and came up with a new compound and design that works wonders in many variator drive applications. The compound and tension member quality is every bit as high as for OEM. In addition to the improvements made in the material, the newly developed belt toothing, which is optimally mated to the drive geometry, ensures enhanced efficiency. Power is reliably transmitted, even at a high gear rate.
