Vehicle Information
Yamaha IT490 Motorcycle - Dual-Sport (1983-1984)
The Yamaha IT490, an enduro and off-road motorcycle, was produced from 1983 to 1984. The "IT" in its name refers to "International Trial," referencing the International Six Days Trial (ISDT). These models featured a single-cylinder, two-stroke, air-cooled 487cc engine, producing approximately 35 HP at 6000 RPM. This engine was specifically tuned for enduro use, delivering more torquey mid-range power compared to its motocross counterpart, the YZ490. The 1983 model year marked a significant redesign for the IT series, introducing the IT490 to replace the IT465 with increased displacement and a redesigned frame. The 1984 model largely carried over the specifications and design updates introduced in 1983. No significant mid-cycle generation or engine changes were noted between the 1983 and 1984 models; the 1984 model was a direct continuation of the updated 1983 design. Each year was offered as a single model, designated IT490K for 1983 and IT490L for 1984, without distinct trim levels. FAQ:
