2019 Suzuki RM-Z450

2019 Suzuki RM-Z450

Completely redesigned for 2019, the RM-Z450 wraps a sleek, race-ready appearance around a stronger engine and a nimble chassis that continues the Suzuki tradition of extraordinarily precise handling. Developed using Suzuki’s RUN, TURN and STOP philosophy that creates a Winning Balance, the 2019 RM-Z450 has stronger brakes for better stopping power, a wider spread of engine muscle with higher peak power, and a chassis that is stronger, lighter and more nimble to raise the standard for cornering performance.

Features may include:

• The 449cc liquid-cooled 4-stroke, 4-valve DOHC engine is the latest incarnation of Suzuki’s proven and reliable, fuel-injected powerplant

• The engine has higher peak horsepower with more torque at lower engine speeds for improved throttle response through the entire rev-range

• The cylinder head intake port shape is changed to tumble flow the fuel/air mixture by 25% to help increase power output

• A 30% larger air cleaner opening is combined with a more direct air cleaner outlet tube path to the throttle body to increase air flow
ADVANCED ELECTRONIC
• The 2019 RM-Z450 features an evolved and faster traction management system. The Electronic Control Module (ECM) continually measures throttle opening, engine speed and gear position and then adjusts the ignition timing and fuel injector duration to fine-tune the engine output to deliver the best traction for the riding conditions.
• The RM-Z450’s traction management system is different from a street-bike traction control system as it does not measure rear tire spin. Because the needs of a motocrosser are different than a street bike, this system offers constant adjustment that maximizes traction at all times.
• The Suzuki Holeshot Assist Control (S-HAC) is a selectable launch system derived from the factory race bike to help riders’ takeoff from the starting gate for an early lead. There are three modes riders can choose for the best option per their skill level and starting conditions. There are three stages to A - Mode and B - Mode of the S-HAC system. This helps riders at the moment of launch, when crossing the gate, and through acceleration to the full-speed. The S-HAC settings for A - Mode on the 2019 RM-Z450 are updated to aid the rider’s throttle control during launches.
TRANSMISSION
• Refined 5-speed transmission enables precise gear shift operation. The transmission feel has been improved with a precisely machined shift cam for accurate gear selection. Specialized machining processes also increase the precision of the matching gears
• The multi-plate, wet-clutch uses rack & pinion clutch release mechanism for precise feel of the engagement and disengagement points while riding
• The new, lighter-weight chain guide is shaped to accurately route the drive chain smoothly
CHASSIS
• The 2019 RM-Z450 features a new frame and swingarm design that continues the Suzuki’s reputation as the best handling motocrossers available
• The new aluminum-alloy twin-spar frame combines cast and extruded sections to achieve superior front-and-rear weight distribution while balancing strength and weight
• The new frame is 700 grams (1.32 lbs.) lighter to improve cornering performance and shock absorption while delivering stable handling
