The Yamaha XT 660 was a dual-purpose motorcycle released as a replacement model for the Yamaha XT 600. The bike was powered by a 660cc liquid-cooled single-cylinder engine and was suitable for both paved and unpaved trails.
Alongside the base model, Yamaha manufactured two other versions, including a more street-oriented supermoto named XT 660X and an adventure-touring version designated as Yamaha XT 660Z Tenere.
In 2012, the Japanese motorcycle manufacturer launched the Yamaha XT 660X, a street-oriented motorcycle with a crisp response to throttle movement, steering, and modern allure.
The bike was equipped with standard features, such as a single headlight unit integrated into a small cowl acting as a wind deflector, a high-mounted front fender, a one-piece dual seat with passenger grab rails, a two-into-two exhausts system with a silencer on each side, and lightweight wire-spoke wheels.
The bike's wheels were fitted with a 320 mm disc engaged by a four-piston caliper on the front and a 245 mm disc tied to a single-piston caliper on the rear, delivering optimum braking performance.
In the performance department, the 2012 Yamaha XT 660X had its soul brought to life by a 660cc four-stroke liquid-cooled single-cylinder engine with a fuel injection system in charge, delivering 48 hp at 6,000 rpm and 60 Nm (44 lb-ft) torque at 5,250 rpm.
