The front suspension uses a telescopic fork with up to 4.3 inches of travel to prevent the rider’s arms from receiving jolts. On the other hand, the rear suspension has twin shocks on the rear wheel. Users can adjust the shocks by 3.2 inches in order to maintain control and handling.

It is equipped with a Yamaha Autolube oil injection system, which utilizes a mechanical oil pump that is controlled by its ECU. A minimum SJ API grade is required for the engine oil, which is SAE 10W-30 Yamalube 2-cycle oil or its equivalent (originally JASO FC or ISO EG-C, EG-D grades).

Furthermore, the fuel tank has a capacity of 5 liters/1.32 US gallons. In all other markets, regular gasoline or petrol can be used, while unleaded fuel is required for Australian units.

Its instrumentation is straightforward and basic, while overall styling is stark and aggressive. Furthermore, it has a two-tone color scheme, and in contrast to the rest of the two-wheeler, the front and rear fenders have different hues.
