An engine modification package designed for the Honda TRX90, this aftermarket upgrade increases the displacement of the engine’s cylinder. Typically, it involves replacing the stock cylinder and piston with larger counterparts, thus expanding the engine’s bore. As an example, a common upgrade will increase the cubic capacity from 86cc to over 100cc.
The installation of such a performance enhancement offers several advantages. It generally results in increased horsepower and torque, improving acceleration and overall engine performance, particularly in off-road environments. Historically, enthusiasts seeking to gain a competitive edge or simply enhance their recreational riding experience have utilized similar modifications. This type of modification offers a cost-effective method for improving performance relative to purchasing a larger displacement ATV.
