Sliding Roller Weights for Vespa Models
Dr. Pulley's 21x15 sliding roller weights are built to work well in Vespa GT 200, GTS 250, and GTS 300 scooters. They are a newer take on scooter variators & roller weights, using a sliding design that changes gear ratios more smoothly. Compared with standard roller weights, this can support quicker acceleration, higher top-end speed, and a longer service life.
A Different Sliding Design
Standard roller weights move by rolling, while Dr. Pulley's version moves by sliding. That change cuts down on wear in the transmission, including when the scooter is running at high speed. The gear ratio holds up over time, which helps the drivetrain last longer.
What You Gain
Because these sliding roller weights widen the usable range of gear ratios, they help with acceleration and pickup from speed. Riders wanting more top-end speed from their scooter will find them a good fit. The weights also compensate for wear automatically, so they keep adjusting and working properly as they age.
