Dr. Pulley 15x12mm Sliding Roller Weights for Minarelli 50cc

Dr. Pulley Sliding Roller Weights for Minarelli 50cc Engines

The Dr. Pulley 15x12mm Sliding Roller Weights are designed specifically for Minarelli 50cc engines. These roller weights are engineered to overcome the common issues of flat spots and inconsistent performance seen with standard weights. This part is one of the Minarelli 50cc / Yamaha jog scooter parts that can significantly improve acceleration and throttle response, making it ideal for both city commuting and spirited rides.

Performance Benefits

These sliding weights utilize an innovative wedge-shaped profile that allows them to glide instead of rotate within the variator ramps. This advanced technology helps to eliminate flat-spotting and reduces wear over time, resulting in longer service life. With broader gear ratios, riders can expect quicker takeoffs and improved speed on open roads.

Weight Options and Selection

Available in weights ranging from 3.0g to 10.0g in 0.5g increments, you can select the appropriate weight for your riding style. Lighter weights (3g-5g) provide faster acceleration, while heavier options (6.5g-10g) are better suited for higher speeds and cruising. It is important to install these weights with the proper orientation, as outlined in the included diagram.
