Vehicle Information
KYMCO MXU 450 ATV (2012-2023)
The KYMCO MXU 450, an all-terrain vehicle (ATV) produced from 2012 to 2023, is known for its robust and consistent platform. Throughout its production run, it featured a reliable 443cc liquid-cooled, SOHC, 4-stroke, 4-valve single-cylinder engine with electronic fuel injection (EFI). This core engine design remained largely unchanged, providing a dependable power source for utility and recreational use. While the fundamental engine and chassis design stayed consistent, minor refinements and trim variations were introduced over the years. Reported horsepower figures saw a slight adjustment, moving from approximately 33 HP in earlier models (2012-2018) to around 31.5 HP in later models (2019-2023). Additionally, the fuel capacity experienced a minor revision. KYMCO offered various trim levels, including the base MXU 450i, the MXU 450i LE (Limited Edition) with special styling or features, the MXU 450i Camo with camouflage bodywork, and the MXU 450i LE Prime, which included premium upgrades like Kaifa gas shocks. These variations primarily focused on aesthetics and feature enhancements rather than significant generational overhauls. FAQ:
