THE RACING WEAPON TO WIN BARBAR-TOTO-BAR BATTLES Race wins deliver great memories, trophies, even championship recognition. For Suzuki, racing success yesterday means championships today and tomorrow.

With a worldwide off-road racing heritage spanning more than 50 years, Suzuki motorcycles have produced many of the world’s greatest racing champions. And while those champions celebrate their victories, Suzuki engineers continue to mark accomplishments by designing motorcycles that extend the winning tradition.

That tradition comes from a high-performance heritage that powers all of Suzuki. The company began racing motorcycles and winning championships on the road more than 50 years ago. With each season, Suzuki has built on its revolutionary history of racing success. That’s why champions continue to choose Suzuki.

The Suzuki RM-Z motocross motorcycles have carried some of the world’s greatest racers to the top of the podium.

It’s evidence that Suzuki’s racing success lives both on the road and off. That’s just part of the Winning Balance that demands motocross riders take an even closer look at Suzuki.

Beauty is skin deep. But power and performance goes all the way to the core.

Look deep and you’ll see the championship-inspired upgrades Suzuki made to the 2013 RM-Z450 and RM-Z250. From years of experience helping racers around the world reach the top of the podium, Suzuki understands that the power of high-performance engineering is often in the details.

A new piston. Upgraded ignition. Redesigned transmission. Suspension changes and more.

Inside and out, Suzuki RM-Z motorcycles are a sight to behold. Beauty is skin deep.

But power and performance goes all the way to the core.

Engine Design Concept For race-winning performance, a motocrosser’s engine needs to be durable, efficient and powerful. To win championships, that engine needs the powerful engineering heritage that comes from Suzuki. Both of the manufacturer’s leading MX bikes – the RM-Z450 and the RM-Z250 – feature fuel-injected engines powered by Suzuki's advanced technology. Suzuki’s fuel-injection expertise has delivered national and world championships in Superbike racing as well as in Motocross and Supercross. High-performance heritage like this serves as the platform for the technological improvements Suzuki built into the 2013 RM-Z450 and RM-Z250. Both bikes deliver increased acceleration, faster throttle response, and broader mid-range power and torque. That means motorcycles that are more competitive and more practical performers to win those bar-to-bar battles.

Piston A motocross bike's single piston must endure an explosive environment, and needs to perform with efficiency and durability. Based on racing data and on-track experience, Suzuki redesigned the piston, piston pin and connecting rod of the RM-Z450. With a new shape, designed through Finite Element Method (FEM) analysis, the same analysis used in factory racing the RM-Z450’s new piston is 13% lighter than in the previous model while retaining rigidity. The reshaped connecting rod is lighter, too and the piston pin was made shorter and more durable. As a result, the RM-Z450 delivers faster throttle response, increased bottom to mid-range power and torque. These traits deliver the efficient durability and powerful performance racers need to win.

Piston pin To reduce friction loss and increase performance, Suzuki coated the RM-Z450’s piston pin with Diamond-Like Carbon (DLC) coating. Suzuki uses similar DLC coatings in its suspension of Hayabusa 1300, the legendary Sportbike. This surface finish helps reduce friction, and increase durability. Add this feature to the piston pin’s shorter and lighter design, and the result is noticeably stronger throttle response.

Exhaust Increasing the exhaust pipe’s length – 50mm for the RM-Z450 (European-spec RM-Zs), and 40mm for the RM-Z250 – better tunes each engine to deliver stronger low-end and mid-range power output. A new muffler has redesigned construction with inner pipes, European-spec RM-Zs meet FIM-enforced sound control regulations without jeopardizing engine power output.

Piston Based on racing data and on-track experience, Suzuki redesigned the piston of RM-Z250. With a new shape – designed through Finite Element Method (FEM) analysis used in factory racing – new piston is 3% lighter than in the previous model while retaining rigidity. It has slightly thinner skirt walls, a shorter piston pin and narrower piston pin boss to help cut weight but not sacrifice performance and durability.

A reinforcing rib on the intake underside adds rigidity; the exhaust underside is left alone for best lubrication and cooling efficiency.

Transmission & Shift Cam RM-Z racers will enjoy smoother and more precise shifting on the 2013 models. The RM-Z250 gets an all-new 5-speed transmission, and the RM-Z450’s is updated and refined for more precise shifting performance. Suzuki changed the shape of the shift cam in both motorcycles to deliver that shifting precision plus smoother shift feel.

Electrical Suzuki updated the electronics that help control the battery-less fuel-injection systems on the RM-Z450 and RM-Z250. The new ECM on both motorcycles now has a higher-performance processor for more powerful engine management. This component upgrade increases response all the way from the rider’s throttle input to the fuel delivery through each bike’s multiple hole fuel injector. And since the ECMs are now waterproof, they resist damage from water and mud, and that helps keep racers at the front of the pack. The electrical systems also get a new magneto with increased power-generating performance for easier starting. And with revised settings in the ignition coil, the RM-Zs deliver strong roll-on power and increased throttle response.

Camshafts Both intake and exhaust cam profile are changed on RM-Z250. The nose angle and lift curve of intake camshaft is increased and exhaust cam timing is revised to achieve higher balance between high performance and ease of power control. The RM-Z450’s intake cam timing and lift are revised, giving the bike’s power a more linear output for better control.

Radiator The RM-Z250’s cooling efficiency is increased thanks to a redesigned radiator fin and revised water hose routing, making the bike’s high-performance power output more stable, even in the most demanding conditions. RM-Z250s also features new by-pass hose routing to simplify occasional radiator maintenance.

Chassis Design Concept Racers know that, in and out of a corner, precision cornering and race-track stability has always been a prime feature of Suzuki’s motocross bikes. But that doesn’t mean engineers left “good enough” alone.

For 2013, the team focused on making both the RM-Z450 and RM-Z250 even more maneuverable, while retaining the bike’s top-notch performance tracking and race-speed stability. With enhanced engine performance as well as refined handling control, the RM-Z450 and RM-Z250 will continue to be the choice of champions, and of those soon-to-become champions.

Frame To ensure the frame’s rigidity is well balanced, engineers reviewed and refined the shape and construction of the frame and the seat rail. The result is an ideal balance of nimble handling for technical sections and straight-line stability for high-speed sections.

Front Fork The RM-Z450 and RM-Z250 now use the new Showa Separate Function front Fork (SFF). The SFF works by separating the damper in left leg from the spring housed in the right leg. Dividing the fork’s functions allows for lighter overall construction with reduced friction, resulting in improved damping performance and ride control. The forks’ inner tubes are now 48mm in diameter; the larger size gives higher stability.

Spring pre-load is adjustable, by gold-anodized adjuster, allowing a wider range of adjustment settings overall.

Rear Suspension To maintain the RM-Z’s renowned handling performance, each bike’s rear suspension features setting changes and adjustments to best match with the increased engine performance and front fork changes.

Overall, the design allows enhanced suspension performance for a wider variety of riders.

Ease of Maintenance Not every champion has a full-time mechanic to handle maintenance tasks. Suzuki engineers know the importance of designing durable and reliable motocross engines, and making their maintenance tasks as simple as possible.

The self-diagnosis function is incorporated in the ECM. It can be notified by using the optional FI indicator (Part No. 36380-28H00). From 2013 model, the FI indicator has engine hour-meter function as well. So riders can track engine-operating time and better manage maintenance intervals.

Suzuki relocated the rich-lean coupler connector location on the RM-Z450 for easier access when fuel-injection settings need to be changed.

A connector between the fuel pump and delivery hose uses a revised lock system for more precise and easier operation. In addition, maintenance plugs for fuel pump and fuel hose are enclosed for convenience.

New muffler body uses conventional bolts in end cap, instead of rivets to simplify the replacement of muffler’s glass wool packing.
