YAMAHAXT 660R 2004 - Present

　　The Yamaha XT 660 was a dual-sports motorcycle manufactured by Yamaha as a replacement for the XT 600. The bike was a development of the original XT series, inspired by those motorcycles used in the Paris Dakar Rally.

　　In 2004, the Japanese motorcycle manufacturer launched the Yamaha XT 660R, a standard Enduro model with an R designation, where R stands for racing. The bike was powered by a 600cc liquid-cooled engine fed by a fuel injection system, delivering smooth power.

　　In the visual department, the bike had standard features, such as a high-mounted front fender, a small headlight integrated into a small cowl with a small wind deflector, a one-piece dual seat, a dual high-mounted exhaust system, and wire-spoke wheels.

　　The motorcycle was built around a tubular diamond steel frame with a 43 mm telescopic fork on the front, offering 225 mm of travel, and a monocross suspension system on the rear, delivering 200 mm wheel travel.

　　The bike's wheels were equipped with a 298 mm disc tied to a dual-piston caliper on the front and a 245 mm disc with a single-piston caliper on the rear, providing optimum stopping power.

　　As for the power figures, the 2004 Yamaha XT 660R had its soul brought to life by a 659cc four-stroke single-cylinder liquid-cooled engine, boasting 48 hp with a peak force at 6,000 rpm and 58 Nm (43 lb-ft) torque at 5,250 rpm.
