Meet the 2014 Suzuki RM-Z450 – a tough motorcycle designed for tough riders. The 2014 model continues the sporty tradition of the 2011 and 2012 models and rewards you with a great handling, and a strong engine.

Talking about the engine, the 2014 RM-Z450 is built around a 449cc, 4-stroke, liquid-cooled, single cylinder, DOHC unit which develops exceptional power from idle to redline and provides a crisp throttle response. The engine’s power is kept under control by a 5-speed constant mesh transmission.

The motorcycle’s ride quality is assured by an innovative Separate Function front Fork (SFF) from Showa. It is also worthy of being mentioned that the front suspension is engineered with a twin-spar aluminum frame enhancing the bikes’ handling and stability on tough tracks.

You won’t complain about the stopping power either as it is assured by a set of capable front and rear discs.

The piston pin has diamond-like carbon (dlc) surface treatment, for less friction and increased durability.
Intake cam timing and amount of lift has been modified for smoother power delivery and control.
Aluminum cylinder with suzuki composite electrochemical material (scem) coating, built for durability, light weight and efficient heat transfer.
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.

Redesigned muffler internal parts, bottom-to-mid range power and torque are increased, resulting in improved performance without losing top end. The new muffler body now uses conventional bolts in end cap instead of rivets to simplify the replacement of the glass wool packing in the muffler.
The muffler body uses conventional bolts, instead of rivets to simplify the replacement of muffler’s glass wool packing.

For quick fuel adjustment setting to suit riding condition, two couplers are enclosed. One is for rich and another for lean fuel setting compared to stock setting. Riders can change fuel setting to best suit the riding conditions by simply connecting either coupler.

449cc 4-stroke liquid-cooled dohc 4-valve fuel-injected engine developed to deliver phenomenal idle-to-redline performance
Through feedback from factory racing, the piston, piston pin and connecting-rod are developed with the use of finite element method (fem) analysis.
The newly designed piston, piston pin and connecting rod are developed with use of finite element method (fem) analysis. The new piston is 13 percent lighter without any compromise to strength and rigidity.

A 5-speed transmission enables precise gear shift operation.

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 2 inches of wheel travel, delivering maximum traction.

Front fork spring pre-load is adjustable, allowing a wider range of settings
Renthal aluminum fatbar is standard equipment. It has more strength and less vibration than aluminum straight handlebars.

Race-inspired waved disc rotors and excel aluminum rims are standard equipment.
Gripper seat, with projected cross-shaped patterns on red-colored top surface to provide additional grip.

Riders can now track engine-operating time and better manage maintenance intervals using the optional fi indicator (part no. 36380-28h00).

Latest version of separate function front fork (sff-type2) from showa, separating the spring and damping tasks. The right leg contains the spring, while the left leg incorporates the cartridge assembly to manage damping. It results in reduced friction, increased absorption performance and weight saving.
