Vehicle Information
Honda TRX450ER ATV (2006-2014)
The Honda TRX450ER, a high-performance sport ATV, was produced from 2006 to 2014. This model, known for its powerful 449cc liquid-cooled, single-cylinder, four-stroke engine, offered riders a robust and agile experience. It was primarily available as the TRX450ER, featuring an electric start, alongside its kick-start counterpart, the TRX450R, for part of its production run. The most significant evolution for this platform occurred in 2006. This major overhaul brought a redesigned engine with a more aggressive cam profile, increased compression (12.0:1), and titanium valves, boosting horsepower to over 41 HP. The carburetor was updated to a 40mm Keihin FCR-type with a TPS, and the chassis saw improvements like an extended swingarm and revised suspension. The TRX450ER, with its electric start, was introduced this year. After 2006, the core specifications remained largely consistent through 2014, with subsequent years being "carryover" models. Minor updates included new color options in 2008, 2009, and 2013, and the discontinuation of the kick-start TRX450R model by 2012, making the TRX450ER the sole offering.
