2016 AMA Motocross Champion
The 2017 Suzuki RM-Z450 features the Suzuki Holeshot Assist Control (S-HAC) system for dominant performance launching out of the gate on virtually any kind of track conditions. After you grab the hole shot, its exceptional power from idle to redline, remarkably crisp throttle response and incredibly precise handling let you dominate the competition. The RM-Z450 — when you’re serious about winning!
49mm SHOWA SFF-Air TAC Fork
The most advanced fork in motocross, the SFF-Air fork is delivered straight from the factory race bikes. It consists of 3 air chambers that riders can easily adjust by using a hand-held air pump to quickly optimise the bike to the conditions, just like setting your tyre pressures. The three-chamber fork uses an Inner Air Chamber that handles the main suspension reaction force (spring-rate), a smaller Balance Air Chamber opposing the main reaction force, and an Outer Air Chamber that supports the main reaction force.
Set-Up Made Easy
Adjusting the Showa SFF-Air fork on the RM-Z450 has never been easier! Download the SFF-Air Support app from Showa on your Apple or Android device to simulate the effect of various changes to your suspension and let this tool help you find the best possible setting for your RM-Z.
*Keep in mind that your first and primary source for settings and service information should always be the Suzuki Owner’s Service Manual, so this should be considered an additional help-aid for set-up.
Suzuki Holeshot Assist Control (S-HAC) is a selectable launch mode system derived straight from our factory race bikes. S-HAC helps riders takeoff from the starting gate for an early lead. S-HAC was first introduced last year on the MY15 RM-Z450, and now a refined version is available on MY16/17 RM-Z250 & RM-Z450. There are three modes riders can choose for the best option per their skill level and starting conditions.
Championship Proven Engine
For race-winning performance, a motocross engine needs to be durable, efficient and powerful. To win championships, that engine needs to come with the experience and know-how that you only get from Suzuki. The 449cm3, 4-stroke liquid-cooled, DOHC, 4-valve fuel-injected engine packs the perfect combination of broad torque and arm-stretching horsepower perfect for today’s racer.
A motocross bike's single piston must endure an explosive environment and needs to perform with efficiency and durability. Through feedback from factory racing, the piston and piston pin were developed using Finite Element Method (FEM) analysis. The RM-Z450 piston pin has Diamond-Like Carbon (DLC) surface treatment, for less friction and increased durability.
The Best Chassis in Motocross
The RM-Z450 features a twin-spar aluminium frame and swingarm that has been developed and refined over the years to achieve the perfect balance between rigidity and flex. It's no secret that Suzuki RM-Zs are known as the best-cornering bikes in motocross.
Renthal Aluminium Fatbar
Fitted as standard equipment , the top-shelf Renthal aluminium Fatbar offers more strength and less vibration than standard size aluminium handlebars.
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.
