The 2022 RM-Z450 remains the champion's choice, as its sleek, race-ready appearance, strong engine, and nimble chassis continue the Suzuki tradition

Technical Specifications

The 449cc, liquid-cooled, four-stroke, four-valve, DOHC engine is the latest incarnation of Suzuki’s proven and reliable fuel-injected powerplant.

The engine has high peak horsepower with strong torque at lower engine speeds for excellent throttle response through the entire rev range.

The cylinder head intake port shape creates a high amount of tumble flow to the incoming fuel/air to increase power output.

The air cleaner’s large and straight opening creates a more direct air path to the throttle body to increase performance.

Suzuki’s advanced fuel-injection system creates extra-smooth power delivery, high fuel efficiency, and superb reliability.

The RM-Z450’s throttle body design locates the fuel injector, fed by a high-pressure fuel pump, so it sprays fuel directly at the butterfly valve to improve atomization of the fuel/air charge.

This throttle body design eliminates complex control linkage, so the rider feels a more direct connection to the engine.

The intake camshaft profile has more valve lift than the prior generation RM-Z450, increasing power at all engine speeds.

The compact aluminum cylinder is finished with Suzuki Composite Electrochemical Material (SCEM) coating for durability, light weight, and efficient heat transfer.

The piston’s casting includes strengthening ribs near the wrist pin bosses to match component reliability to the engine’s high horsepower.

Engine starting is simple and efficient due to a long kick-start lever, well-matched internal gear ratios, a large air cleaner and breather system, plus an automatic decompression system that works precisely and efficiently (eliminating the need for a heavy and costly electric start system).

The high-flow exhaust system complies with AMA sound regulations.

Tough resin engine protectors help guard the coolant pump (on the right) and the stator cover (on the left) from debris and stones.
