The 1983 Yamaha IT490 is a testament to the raw, untamed spirit of early motocross bikes. Its 487cc single-cylinder engine delivers a healthy 35 horsepower and 42 Nm of torque, providing a punchy, responsive feel that demands respect. Weighing in at 125 kg, the IT490 offers a relatively lightweight package for its era, contributing to its nimble handling on the dirt. The 5-speed gearbox allows riders to exploit the engine's power across a range of terrains. Ergonomically, the IT490 is a product of its time, with a focus on functionality over outright comfort. The adjustable 43mm telescopic forks provide decent front suspension, while the drum brake up front is a reminder of the simpler braking technology of the past. With a fuel tank capacity of 13.6 liters, riders could expect a reasonable range for off-road adventures. This machine is squarely aimed at experienced riders who appreciate the challenge and visceral experience of riding a classic big-bore two-stroke. It's a bike that rewards skill and demands attention, offering a unique connection to the roots of motocross.
