Yamaha Xt 660
The Yamaha XT660R was introduced in 2004 as a successor to the long-running XT600 series, featuring a modernized single-cylinder engine and updated chassis to compete in the dual-sport segment. It was offered in two variants: the XT660R (enduro/dual-sport) and the XT660X (supermoto), both sharing the same core engine platform. The model gained popularity for its reliability, low maintenance costs, and versatility, remaining in production largely unchanged until around 2016-2017.

What Buyers Should Know
Rock-Solid Engine Reliability
The XT660's single-cylinder 660cc engine is renowned for longevity, often exceeding 100,000 km with basic maintenance. It shares DNA with Yamaha's proven XT lineage, making parts widely available and affordable.
Watch the Cooling System
The XT660R/X models can run hot in heavy city traffic, so inspect the radiator and coolant hoses carefully on used bikes. Overheating issues are common when the cooling system is neglected.
Strong Resale Value
The XT660 holds its value exceptionally well due to its dual-sport versatility and cult following among adventure riders. A well-maintained example typically retains 60-70% of its value after five years.
