3 That tradition comes from a highperformance 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 and RMZ 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. Photo : RMZ250 modified for All Japan Motocross Championship

4 Background Photo: RMZ450 and RMZ250 modified for All Japan Motocross Championship Look deep and you ll see the championshipinspired upgrades Suzuki made to the 2013 RMZ450 and RMZ250. From years of experience helping racers around the world reach the top of the podium, Suzuki understands that the power of highperformance engineering is often in the details. A new piston. Upgraded ignition. Redesigned transmission. Suspension changes and more. Inside and out, Suzuki RMZ motorcycles are a sight to behold. Beauty is skin deep. But power and performance goes all the way to the core.

5 Engine Design Concept Exhaust For racewinning 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 RMZ450 and the RMZ250 feature fuelinjected engines powered by Suzuki's advanced technology. Suzuki s fuelinjection expertise has delivered national and world championships in Superbike racing as well as in Motocross and Supercross. Highperformance heritage like this serves as the platform for the technological improvements Suzuki built into the 2013 RMZ450 and RMZ250. Both bikes deliver increased acceleration, faster throttle response, and broader midrange power and torque. That means motorcycles that are more competitive and more practical performers to win those bartobar battles. Increasing the exhaust pipe s length 50mm for the RMZ450 (Europeanspec RMZs), and 40mm for the RMZ250 better tunes each engine to deliver stronger lowend and midrange power output. A new muffler has redesigned construction with inner pipes, Europeanspec RMZs meet FIMenforced sound control regulations without jeopardizing engine power output RMZ450 Exhaust system 2013 RMZ450 ENGINE (The parts shown in yellow are new for 2013) 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 ontrack experience, Suzuki redesigned the piston, piston pin and connecting rod of the RMZ450. With a new shape designed through Finite Element Method (FEM) analysis used in factory racing new piston is 13% lighter than in the previous model while retaining rigidity. The reshaped connecting rod is lighter, too. The piston pin is made shorter and durable. As a result, the RMZ450 delivers faster throttle response, plus increased bottom to midrange power and torque. These traits deliver the efficient durability and powerful performance racers need to win. Intake camshaft Piston Cam chain guide Piston pin 2013 RMZ450 Piston & piston pin Connecting rod Piston pin To reduce friction loss and increase performance, Suzuki coated the RMZ450 s piston pin with DiamondLike 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.

6 2013 RMZ250 ENGINE (The parts shown in yellow are new for 2013) Ignition coil Exhaust camshaft Intake camshaft Transmission & Shift Cam RMZ racers will enjoy smoother and more precise shifting on the 2013 models. The RMZ250 gets an allnew 5speed transmission, and the RMZ450 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 RMZ250 Transmission Radiator The RMZ250 s cooling efficiency is increased thanks to a redesigned radiator fin and revised water hose routing, making the bike s highperformance power output more stable, even in the most demanding conditions. RMZ250s also features new bypass hose routing to simplify occasional radiator maintenance. Piston pin Crank pin Piston Clutch release Transmission Electrical Suzuki updated the electronics that help control the batteryless fuelinjection systems on the RMZ450 and RMZ250. The new ECM on both motorcycles now has a higherperformance 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 powergenerating performance for easier starting. And with Muffler revised settings in the ignition coil, the RMZs deliver strong rollon power and increased throttle response.

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. Oil strainer with magneto 2013 RMZ250 Piston & piston pin Both intake and exhaust cam profile are changed on RMZ250. 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 RMZ450 s intake cam timing and lift are revised, giving the bike s power a more linear output for better control RMZ250 Intake & exhaust camshafts 2013 RMZ450 CHASSIS (The parts

7 Chassis Design Concept Racers know that, in and out of a corner, precision cornering and racetrack 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 RMZ450 and RMZ250 even more maneuverable, while retaining the bike s topnotch performance tracking and racespeed stability. With enhanced engine performance as well as refined handling control, the RMZ450 and RMZ250 will continue to be the choice of champions, and of those soontobecome champions. Frame 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 straightline stability for highspeed sections. Front Fork The RMZ450 and RMZ250 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 preload is adjustable, by goldanodized adjuster, allowing a wider range of adjustment settings overall RMZ450 Spring preload adjuster Under bracket Rear Suspension Front fork To maintain the RMZ 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 RMZ450 Rear suspension shown in yellow are new for 2013) Ease of Maintenance Not every champion has a fulltime 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 selfdiagnosis function is incorporated in the ECM. It can be notified by using the optional FI indicator (Part No H00). From 2013 model, the FI indicator has engine hourmeter function as well. So riders can track engineoperating time and better manage maintenance intervals.. Suzuki relocated the richlean coupler connector location on the RMZ450 for easier access when fuelinjection 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 RMZ450 Front fork cutawey
