The new RM-Z450’s 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 first RM-Z450 traction management system debuted for 2008, and a revised second -generation system arrived for 2013. Now in the 2018 RM-Z450’s third-generation traction management system, a revised ECU has fully 1.6-times faster data processing and 2.5-times more memory capacity than the first-generation system.
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, swingarm significantly improve turning performance, whether you’re railing a berm or diving into the inside line. The head pipe point is relocated 10mm back, resulting in a shorter, 1,480mm wheelbase while the weight distribution forward for 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.
All-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. 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 offers more consistent feeling throughout a moto. Machine set-up and daily maintenance is also easier for a wide range of riders. The upper triple-clamp is also lighter with optimised dimensions.
The 2018 RM-Z450 is the first production motocross bike to feature the BFRC shock as standard equipment. The new shock shares technology with the all-new 2018 GSX-R1000R sportsbike. 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.
The 2018 RM-Z450 has a fresh new look that enhances Suzuki’s already distinctive design theme. The evolution starts with aggressive “Beak DNA” which projects a dynamic arrow form extending from the front fender through the radiator shrouds. Finished in Suzuki yellow with new team graphics and logos, the most potent RM-Z450 yet is recognisable at a glance. The styling refresh also extends to the seat shape, which makes moving between seated and standing positions easier, as well as shifting weight front or rear. And for racers, easier is always faster!
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.
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.
Fitted as standard equipment , the top-shelf Renthal aluminium Fatbar offers more strength and less vibration than standard size aluminium handlebars.
