We have spent multiple months working with Gates to produce a product to exceed what is currently on the market. After several meetings and tests, We have found the optimal belt width for the Sur Ron and Segway is 16 mm. There have been many belts made available in the 17mm width with the thought being that the widest possible fit, will be the strongest. Unfortunately, that has come to be untrue and confirmed during our time working with Gates-Belts engineers. Most commonly due to the slight misalignment of the motor and jackshaft pulley, the belt can push its way to the outside edge and begin causing friction on the sides of the belt. This increased friction will cause pre-mature failure of most belts, and unwanted pulley wear. Not to mention belt tracking which will limit the belt's actual contact points on your pulley.

Furthermore, the OEM Sur Ron sprocket pulleys are HTD style (High Torque Drive) and the Gates GT4 Belts are a high-torque synchronous belt that has an ever so slightly different tooth shape. This makes it critical according to Gates engineers to make sure the belt has slight clearance to the flanged pulleys. Allowing a .5mm clearance to each side of the pulley has seemed to increase the Sur Ron GT4 Powergrip's belts longevity and reduce the heat multiplier caused by friction and tight tolerances. These are the correct specifications recommended for the Sur Ron and Segway HTD pulleys provided by the belt engineers. OEM (stock) belts are not made to last. They wear and break far sooner than many aftermarket belts, which is why replacing your Sur-Ron or Segway belt is a good investment in your bike's future.

This heavy-duty replacement belt is a direct fit for your Light Bee X, X160, or X260 and is far more durable than your stock belt, and any other aftermarket belt. It has undergone numerous stress tests to ensure that you get long-lasting wear from it.
