Vehicle Information
Honda Sportrax 90 ATV (1993-2008)
The Honda Sportrax 90, also known as the TRX90, is a popular youth ATV produced from 1993 to 2008. Designed for young riders aged 12 and older, it stands out for its reliable engine and robust platform. It was powered by an air-cooled, SOHC single-cylinder four-stroke engine of 86cc (sometimes rounded to 89cc), producing approximately 6 horsepower. While the core engine remained largely unchanged, the Sportrax 90 received significant updates. In 2006, it gained an electric starter, new suspension settings, and TRX450R-inspired bodywork. Designations also evolved, from FourTrax 90 (TRX90) to TRX90EX around 2007, and then TRX90X in 2008. These changes primarily modernized the riding experience and aesthetics. FAQ:
