Honda TRX450R ATV (2006-2014)

The Honda TRX450R, produced from 2006 to 2014, is a high-performance sport ATV renowned for its racing capabilities and robust 449cc liquid-cooled, single-cylinder, four-stroke engine with a Unicam cylinder head. This model range is defined by a significant overhaul introduced in 2006, which established its core specifications for the remainder of its production.

The 2006 model year marked a pivotal second generation for the TRX450R. Key improvements included an increased compression ratio (12.0:1), a revised bore and stroke (96.0 mm x 62.0 mm), and a more aggressive cam profile. The carburetor was updated to a 40mm Keihin FCR flat-slide with TPS for better throttle response. Additionally, the TRX450ER, an electric-start variant, was introduced, offering a convenient alternative to the standard kick-start model. Chassis and suspension also received updates, including an extended swingarm and increased rear suspension travel. From 2006 to 2014, the engine and chassis remained largely consistent, with subsequent years primarily featuring minor cosmetic changes like new color options.
