Technical Overview
2009 UM MTX-450R Technical Analysis & Specification Breakdown
Built around UM's atv motorcycle platform, the 2009 UM MTX-450R pairs a 449 cc (27.4 cu in) liquid-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 51 HP (37.2 kW), transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 113.6 HP per liter, the engine character is reflecting a performance-oriented street tune that balances strong mid-range pull with an energetic top-end rush.
Rider ergonomics and chassis geometry center around a 884 mm (34.8 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,829 mm (72 in) wheelbase engineered for planted straight-line stability. The 10.97-liter (2.9 US gal) fuel tank supports practical everyday commuting and weekend road stints.
