Wraps officially come off the 2018 RM-Z450 production model
Suzuki Motorcycles Australia has officially unveiled what arguably has been the most anticipated motocross release this year, the all-new 2018 RM-Z450.

Motocross is a relentless game, and the technology and training required for bike and rider to excel in the sport are too. Suzuki has poured more than 40 years of open-class racebike engineering into the 2018 RM-Z450 to make it the hardest-hitting, sharpest-handling, best-balanced and most rider-friendly production motocrosser in the company‰Ûªs rich history.

The 2018 RM-Z 450
In motocross, you‰Ûªve got to get instantly hooked up ‰ÛÒ both out of the gate and off the corners ‰ÛÒ and also blisteringly fast down the straights. To give riders the advantage, the redesigned 2018 RM-Z450 engine has more low-end torque, a flatter overall torque curve, faster and yet more controllable throttle response, and more peak power.

Inside the airbox, the air-filter aperture is now 30-percent larger for enhanced airflow, and an MXGP-style mudguard helps keep mud and dirt out, contributing to greater engine durability. The outlet tube leading from the airbox to the fuel-injection throttle body is also straighter, reducing intake resistance for increased power across the rev range. The throttle body is likewise revised, providing a more uniform fuel-air mixture to further increase power while providing a smoother throttle feel. Increased fuel-pump pressure strengthens the air-fuel mix for enhanced response, and the elimination of a throttle linkage further improves throttle feel.

The fuel-injector spray path now aims fuel upward to hit the throttle butterfly valve directly for improved atomisation. Inside the intake port, the shape is updated for improved tumble flow of the charge as it enters the cylinder, boosting power at all engine speeds. The intake-port shape is matched to a new high-lift intake-cam profile, which further improves intake efficiency and engine output. Inside the combustion chamber, a new piston-rib design adds strength and durability to match the engine‰Ûªs higher output. While an updated muffler conforms to the latest sound-control regulations.

The new RM-Z450‰Ûªs electronic systems work seamlessly with the rider to get the power to the ground. To maximise traction for conditions, the engine control module (ECM) automatically adjusts ignition timing and fuel injection based on throttle position, engine speed and gear position.

The traction management system first debuted for 2008 RM-Z450, and a revised second -generation system arrived for 2013. Now the 2018 RM-Z450‰Ûªs third-generation traction management system, a revised ECU features 1.6-times faster data processing and 2.5-times more memory capacity than the first-generation system.

By interpreting throttle and gear positions, S-HAC continuously alters the timing to maximise power delivery during the three critical stages of a start, including: 1) The exact moment of launch; 2) Getting over the gate; and 3) Accelerating up the start straight. Regardless of the rider, the track conditions, or whether the starting pad is dirt, mud or concrete, S-HAC automatically adapts to provide the quickest and strongest possible drive forward. The system returns the ignition timing to normal operation six seconds after launch, when the rider shifts into fifth gear, or when the throttle is closed, giving the rider ample time to bust out of the gate towards the first turn.

The latest version of S-HAC included on the new RM-Z450 gives riders a choice of three settings which can be quickly selected via a handlebar-mounted switch. The ‰ÛÏA‰Û

Lighter, more rigid and more agile, the 2018 Suzuki RM-Z450 gives riders sharper handling, better feel and more control than ever. Its all-new lightweight frame and swingarm significantly improve turning performance, whether you‰Ûªre railing a berm or diving into the inside line. The head pipe point has been relocated 10mm back, resulting in a shorter, 1,480mm wheelbase while the weight distribution has been brought forward for increased agility and stability.

Frame advancements include a more rectangular cross-section for the main spars, improved fore-aft rigidity and optimised overall rigidity, together with a 700g weight reduction. All of which directly increase cornering, shock-absorbing ability and handling stability.

Swingarm upgrades include thinner materials for a 100g weight reduction and optimised rigidity, which translates to increase cornering and stability. Additional chassis upgrades include new seat rails with hexagonal tubing for slimmer dimensions and better rigidity.

The revised seat-rail shape also allows more airbox capacity and easier air-cleaner service access, while allowing room for the RM-Z450‰Ûªs new Showa Balance Free Rear Cushion (BFRC) shock.

In the cockpit, a new straighter bend for the Renthal Fatbar aluminium handlebar helps riders shift their weight forward for improved cornering. And finally, a lighter chain guide provides more even contact and higher durability, while an engine protector guard shields the water pump and magneto cover from potential damage.

New Showa front and rear suspension delivers improved responsiveness and terrain following, enhanced ability to absorb forces, better chassis stability, feedback and terrain feel, and improved comfort. The rider payoff is improved control, quicker lap times and less fatigue under hard training or racing conditions.

Up front, an updated 49mm Showa coil-spring fork based on works A-type design replaces the SFF-Air fork of the previous-generation RM-Z450. Performance has been increased significantly and more consistent throughout a moto. Machine set-up and daily maintenance is also easier for a wide range of riders.

While out back, a new Showa Balance Free Rear Cushion (BFRC) shock shares technology with the new 2018 GSX-R1000R sportsbike and is also the first production motocross bike to feature this new shock seen on factory race bikes as standard equipment. The design balances pressure above and below the piston to better control the stroke and smooth out reactions to bumps and chop, even under severe braking.

Lighter wheel rims and new Bridgestone Battlecross X30 tyres maximise grip for improved agility and control in a wide range of track conditions. Finished in durable black for a factory look, the new rims have an optimised cross section, which maintains strength while also reducing critical rotating mass by 70g total. A larger 270mm wave disc up-front improves stopping performance.

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.

The 2018 RM-Z450 has a fresh new look that enhances Suzuki‰Ûªs already distinctive design theme. The evolution starts with aggressive ‰ÛÏBeak DNA,‰Û
