Record conflict: The product title and introductory copy describe a Trailmaster/JHL MK125 dirt bike with a 125cc engine, 4-speed manual transmission and 29.5-inch seat height. The specification table below instead lists a 177cc EFI 2WD utility vehicle with automatic P/R/N/F transmission, dump bed, roof, windshield, hitch receiver and 1,543 lb dry weight. These records should not be treated as the same configuration without verification.
