Choosing scooter roller weights If you are considering upgrading your scooter's performance, a set of scooter roller weights tailored to your riding needs is an inexpensive addition that will enhance your scooter's acceleration and speed performance. Usually one of the easiest modifications that a scooter owner can do, a scooter roller weight kit of six will make a big difference on how your scooter accelerates. Most modern motor scooters use the Continuously Variable Transmission (CVT) system that provides the smooth transmission gearing in the popular twist & go style of scooters. Roller weights are an essential part of the CVT variator, using centrifugal force to push outward and change the gear ratio. Should I go lighter or heavier? A lighter scooter roller weight will require higher RPMs (and create more rapid acceleration) but will cut down the top speed. This may be preferable for urban stop and go riding where acceleration speed is of more concern than overall highway speed. A heavier scooter roller weight will do the the exact opposite; the lower engine RPMs needed to push the weights means a smoother, if less rapid acceleration. However the same physics involved will generate a higher highway speed. Think of the lighter weights for the city streets and the heavier ones for the open road; helping to make it sort of a 'town or county' decision that is best suited to the rider's personal requirements. Or in short: Lighter roller weights = faster take-off acceleration, lower top speed. Heavier roller weights = slower take-off acceleration, higher top speed. It's your choice. So what do these numbers mean? Although the weight of the rollers can be changed to achieve the desired performance, the external size must remain the same as that installed at the factory. Each CVT variator is designed to use a single roller size, with different weights being the only adjustment. Roller weights are identified by their external dimensions in millimeters, and their weight in grams. As an example, a 19x17-11 roller weight is 19 millimeters in diameter, 17 millimeters in width, and weighs 12 grams. Some brands mold the size directly onto the weight. For other brands you may have to break out the a metric ruler or measuring tape. If all else fails, your scooter's owner's manual will give the correct dimension size and possibly an acceptable weight range
