Ahead Of The Pack
The RM-Z450 continues to evolve for 2015, delivering a higher level of performance while maintaining the best features from the previous model. The 449cc 4-stroke liquid-cooled DOHC 4-valve fuel-injected engine along with new performance upgrades straight from the factory race bike is the reason why champions choose Suzuki!
The 49mm Showa SFF-Air suspension
An evolution of the original SFF system with no fork spring, reduced weight, increased inner tube diameter, and increased damper rod/piston size. The SFF-Air is made of 3 chambers and riders can change the spring rate with an air pump instead of changing out the fork spring/s.
The Suzuki Holeshot Assist Control (S-HAC)
A selectable launch mode system derived straight from the factory race bike to help riders launch from the starting gate for an early lead. There are three modes so riders can choose the best option for their skill level and riding conditions. A Mode: For hard surfaces or less than ideal conditions at the starting gate & B Mode: When there is better traction and a more aggressive launch is needed.
Engine starting has been improved
A longer kick starter lever for easier operation, a redesigned kick drive gear, a relocated kick idle gear, a newly added breather gear, and a redesigned decompression system that works more precisely and efficiently.
A redesigned frame
Features increased rigidity and reduced weight by 4% from the previous design.
Has been enhanced with the radiator hose connection being changed from a T-shaped to a Y-shaped design for more equal water flow between left and right radiators. Water flow is also increased by 16% with a redesigned water pump cover and the water hose is now directly connected to the water pump.
Improved gear shift feel
A revised gear shift cam for a more precise operation. The machining process of each gear was also reviewed to increase precision of matching gears.
Rich & Lean Fuel Couplers
Riders can adjust the engine performance to suit varied track conditions. By plugging in either of two additional fuel-setting couplers, riders can opt for a richer-than-stock or leaner-than-stock fuel setting to make the most of any riding conditions. Included with the bike, these couplers can be easily plugged in trackside.
Renthal Aluminium Fatbar
Fitted as standard equipment , the top-shelf Renthal aluminium Fatbar offers more strength and less vibration than standard size aluminium handlebars.
- 449cm3 4-stroke liquid-cooled DOHC 4-valve fuel-injected engine developed to deliver phenomenal idle-to-redline thrust.
- Through feedback from factory racing, the piston, piston pin and connecting-rod are developed with use of Finite Element Method (FEM) analysis.
- The piston pin has Diamond-Like Carbon (DLC) surface treatment, for less friction and increased durability.
- Lightweight, battery-less, motocross-use electronic fuel injection system with progressive throttle linkage makes for efficient power delivery.
- 12-hole fuel injector delivers a fine fuel/air mist for efficient operation.
- Aluminium cylinder with Suzuki Composite Electrochemical Material (SCEM) coating, built for durability, light weight and efficient heat transfer.
- Slim chassis design makes for a slim riding position, opening up the cockpit to allow the rider to actively take control of the machine.
- Showa piggyback-reservoir rear shock with high/low-speed compression damping adjustment, plus rebound damping and spring preload adjustments.
- The rear shock, working through Suzuki's superlative rising-rate linkage system, provides 310mm of wheel travel, delivering maximum traction.
- Race-inspired waved disc rotors and Excel aluminium rims are standard equipment.
- Gripper seat, with projected cross-shaped patterns on grey-coloured top surface provides the rider with additional grip.
- Maintenance cap for fuel pump and plug for fuel hose are enclosed for ease of maintenance when customer removes fuel tank for maintenance purpose.
- The muffler body uses conventional bolts, instead of rivets to simplify the replacement of muffler's glass wool packing.
