Honda introduced this sport ATV for the 1993 model year as the TRX300EX, a mid-size performance quad that helped define the entry-level sport-ATV category in the 1990s. Honda’s own historical chronology lists the model among its major products for 1993, and later owner-manual records show it continuing through the 2008 model year under the Sportrax 300EX name. The model was aimed at riders who wanted a simpler, more approachable sport machine than Honda’s race-focused quads, while still offering the brand’s reputation for durability and easy ownership.
Across its run, the nameplate remained closely associated with Honda’s air-cooled four-stroke sport ATV formula and became one of the company’s best-known recreational off-road models. Early examples were commonly marketed as FourTrax 300EX, while later literature uses Sportrax 300EX, but these are part of one continuous production history rather than separate revivals. The model earned a strong reputation with trail riders and casual racers for being forgiving, dependable, and easy to modify, which helped it stay relevant for an unusually long time in a fast-changing segment.
Production ended after the 2008 model year, closing a 16-year continuous run for a nameplate that became a familiar sight in Honda’s ATV lineup and a long-lived favorite among sport-quad enthusiasts.
