Picked from current listings using relevance, seller signals and listing quality.
Most 500cc motocross bikes are powerful, big-bore machines and are usually better suited to experienced riders. Always consider rider ability, bike condition and intended use.
Check engine condition, starting behaviour, compression, frame wear, suspension, brakes, parts availability, rebuild history and whether the advert gives enough detail.
Some Honda CR500 bikes attract collector interest, especially clean or original examples, but value depends on condition, history, originality and demand at the time.
Maintenance depends on the specific bike and how it has been used. For older big-bore bikes, check rebuild evidence, spares availability and signs of hard use carefully.
