Yamaha IT 490 1983 Wreckers, Dismantlers, Wrecking, Parts, and Accessories


The Yamaha IT 490 1983 was a powerful and reliable off-road motorcycle designed for the serious motocross rider.

It was the flagship model of Yamaha’s IT (International Trials) line of dirt bikes and offered unparalleled performance and versatility for its time.

The bike featured a high-strength, lightweight frame that was made of chrome-moly steel, ensuring maximum rigidity and durability even in the harshest conditions.

The suspension system was equally impressive, with a beefy 43mm front fork and a rear mono-shock that provided excellent handling and control.

One of the standout features of the IT 490 was its advanced power valve system.

This technology allowed the engine to deliver a smooth and consistent power output across the entire RPM range, making it easier for riders to maintain control and achieve faster lap times.
