Used parts for the Honda TRX250EX Sportrax (later renamed TRX250X) are available at Sun Coast Cycle Sports. This entry-level sport ATV uses a 229cc air-cooled SOHC single-cylinder engine with a five-speed manual transmission plus reverse. Produced from 2001 onward, the TRX250EX/X is positioned as a beginner-friendly sport quad with enough capability for experienced recreational riders. At approximately 385 pounds wet weight, it is light and manageable on trails. Every component is inspected, photographed individually, and ships from our Odessa, Florida facility.
TRX250EX / TRX250X generation and parts compatibility
| Model | Years | Engine | Key details |
|---|
| TRX250EX (Sportrax) | 2001-2008 | 229cc single, air-cooled, carbureted | 5-speed + reverse, electric start, solid rear axle |
| TRX250X | 2009+ | 229cc single, air-cooled, EFI (later years) | Renamed, fuel injection on later models, same basic platform |
The TRX250EX and TRX250X share the same basic platform. Most chassis components, engine internals, and bodywork interchange across the production run. The primary differences are the name change (Sportrax to X), the eventual addition of fuel injection replacing the carburetor on later models, and minor cosmetic updates. When sourcing fuel system components, verify whether the specific model year uses a carburetor or fuel injection.
Common TRX250EX/X failure points and replacement parts
Carburetor maintenance (carbureted models): The Keihin carburetor on earlier models requires periodic cleaning, especially after storage. Pilot jet clogging and float valve deterioration cause hard starting and rough idle. A rebuild kit resolves most fuel delivery issues.
Valve adjustment: The air-cooled SOHC engine requires periodic valve clearance checks and adjustments. Tight valves cause hard starting and power loss; loose valves produce excessive noise and can lead to valve seat damage.
Rear axle bearing wear: The solid rear axle bearings can wear under aggressive riding conditions, producing a noticeable wobble or clicking sound from the rear end. Bearing replacement restores proper wheel alignment.
Plastics damage: As a beginner-oriented machine, the TRX250EX/X frequently sustains cosmetic damage from trail drops and minor collisions. Replacement plastics and fender sets are among the most commonly ordered parts.

Frequently asked questions
Q: Are TRX250EX and TRX250X the same ATV?
Essentially yes. Honda renamed the Sportrax 250EX to the TRX250X around 2009. The core platform (engine, frame, suspension) remained the same. Later TRX250X models received fuel injection, which is the most significant mechanical change. Most chassis and engine parts interchange across the entire production run.
Q: Is the TRX250EX a good beginner ATV?
Yes. The TRX250EX/X is specifically designed as an entry-level sport quad. The 229cc engine provides manageable power, the five-speed manual transmission teaches proper riding technique, and the light weight makes it easy to handle on trails. It is capable enough for experienced recreational riders while being forgiving for beginners.
Q: What is the difference between the TRX250EX and the TRX250 Recon?
The TRX250EX Sportrax is a sport-oriented ATV with a manual five-speed transmission, chain drive, and sport-style suspension designed for trail fun. The TRX250 Recon (TRX250TM/TE) is a utility-oriented ATV with either manual or electric-shift transmission, shaft drive on some models, and work-oriented features. They share the same 229cc air-cooled engine, so many engine internals are compatible. Chassis, drivetrain, and bodywork are model-specific and do not interchange between sport and utility variants.
