engine
The heart of a water-cooled in-line 4-cylinder DOHC with a displacement of 400cc. Equipped with an original valve control system "HYPER VTEC Revo" that switches the number of operating valves per cylinder to 2 valves / 4 valves according to the number of revolutions, not only powerful torque characteristics in the entire range, but also during cruising It is a power unit that pursues fuel efficiency. The fuel supply system adopts "PGM-FI (Programmed Fuel Injection System)" that improves combustion efficiency by controlling the optimum fuel injection amount and timing according to the driving situation. In addition, the throttle body is equipped with an "IACV (Idle Air Control Valve)" that stabilizes the idle speed and improves startability. We are pursuing smooth driving in a wide range of areas, from powerful low-speed ranges to relaxed high-speed ranges.
Chassis
The double cradle frame combines suppleness and firm rigidity to pursue light sports riding and a sense of stability at high speeds. In addition, by reinforcing the seat rail part, it is compatible with accessories such as rear carriers and top boxes.
Front suspension
The front suspension is a telescopic type equipped with a preload adjuster that can be adjusted steplessly. Achieves high road followability and excellent rigidity balance, resulting in light and stable handling. The front fork is equipped with a chipping guard that reduces damage to the inner tube.
Rear suspension
Achieves both sharp driving and ride quality.
Along with an aluminum swing arm, a damper with a reservoir tank is attached to the rear. In addition, it is equipped with a preload adjuster that can be adjusted in 5 steps, and in combination with the front, it is possible to make fine adjustments according to weight and physique.
ABS
ABS that avoids locking the front and rear wheels.
All types are equipped as standard with "ABS (Anti-Lock Braking System)", which is reassuring for driving on rainy days. Based on the information from the wheel speed sensors installed on the front and rear wheels, the ECU with self-diagnosis function monitors the tire lock while driving. When it detects a tendency to lock the tires due to excessive braking or sudden changes in the road surface, it avoids the tires from locking and supports vehicle body control
Brake system
A sense of security enhances the enjoyment of driving.
A 4-pod caliper is used for the front brake body, and a lightweight, large-diameter floating disc with a diameter of 296 mm is double-mounted. The rear uses a one-sided 1-pod caliper mounted on the axle. In addition, the wheel adopts a 10-spoke wheel that crosses left and right in pursuit of rigidity balance. It also contributes to the reduction of unsprung weight.
Exhaust system
A distinctive, thick and sharp straight-four sound.
The exhaust system that uses the 4-2-1 exhaust system is equipped with an exhaust gas reburning system and a catalyst device (catalyzer) that purifies harmful components in the exhaust gas. The muffler has a light appearance, the attractive sound production unique to the straight-four engine, and even the environmental performance are taken into consideration.
