2015 Suzuki RM-Z450, 2015 Suzuki RM-Z450 Made with Champion DNA The RM-Z450 continues to evolve for 2015, delivering a higher level of performance while maintaining the great balance of the current model. The 449cc 4-stroke liquid-cooled DOHC 4-valve fuel-injected engine along with new performance upgrades straight from the factory is the reason why champions choose Suzuki! Features May Include The Suzuki Holeshot Assist Control (S-HAC) is a selectable launch mode system derived straight from the factory race bike to help riders launch from the starting gate for an early lead. There are three modes so riders can choose the best option for their skill level and riding conditions. A Mode: For hard surfaces or less than ideal conditions at the starting gate, hold down the S-HAC switch for more than 0.7 second, B Mode:When there is better traction and a more aggressive launch is needed, hold down the S-HAC switch for more than 1.8 second. The SFF-Air suspension is an evolution of the SFF system with no coil spring, reduced weight, increased inner tube diameter, and increased damper rod/piston size. The SFF-Air is made of 3 chambers and riders change the spring rate with an air pump instead of changing out the coil springs. Engine start has been improved with a longer kick starter lever for easier operation, a redesigned kick drive gear, a relocated kick idle gear, a newly added breather gear, and a redesigned decompression system that works more precisely and efficiently. A redesigned frame increases rigidity and reduces weight by 4% from the previous model. Cooling performance has been enhanced with the radiator hose connection being changed from a T-shaped to a Y-shaped design for more equal water flow between left and right radiators. Water flow is also increased by 16% with a redesigned water pump cover and the water hose is now directly connected to the water pump. The gear shift feel has been improved with a revised gear shift cam for a more precise operation. The machining process of each gear was also reviewed to increase precision of matching gears. The piston pin has Diamond-Like Carbon (DLC) surface treatment, for less friction and increased durability. Aluminum cylinder with Suzuki Composite Electrochemical Material (SCEM) coating, built for durability, light weight and efficient heat transfer. Lightweight, battery-less, motocross-use electronic fuel injection system with progressive throttle linkage makes for efficient power delivery. 12-hole fuel injector delivers a fine fuel/air mist for efficient operation. For quick fuel adjustment setting to suit riding condition, two couplers are enclosed. One is for rich and another for lean fuel setting compared to stock setting. Riders can change fuel setting to best suit the riding conditions by simply connect
2015 Suzuki RM-Z250, 2015 Suzuki RM-Z250 The 2015 RM-Z250 contains all the necessary components for a championship bike. Class-leading handling aided by the Showa Separate Function front Fork, combined with a substantial four-stroke engine, the RM-Z will suffice for any rider looking to carve up the track and win! Features May Include ECM ignition program has been changed for improved starting performance. Stylish two-tone radiator shrouds with new aggressive graphics and yellow number plate accentuate the RM-Z250's agile looks. Two couplers are included for quickly adjusting the fuel setting to suit the riding conditions. One is for a richer fuel setting than the stock setting and the other is for a leaner fuel setting. Riders can change the fuel setting to suit the best riding conditions by simply connecting either coupler. The 249cc, 4-stroke, fuel-injected, DOHC engine, with a compact and lightweight design, powers the RM-Z250's championship-winning performance. Through feedback from factory racing, the piston and piston pin is developed using Finite Element Method (FEM) analysis. The crankcase reed valve has been revised for more efficient lubrication. The new oil strainer has a stronger magneto to capture contaminants from the engine oil. Together these changes contribute to better throttle response and smoother power delivery. The advanced battery-less fuel-injection (FI) system features a 44mm throttle body with progressive throttle linkage and a 16-bit computer. The fuel injection system uses a unique capacitor-assisted starting system and is powered by a durable, lightweight magneto-generator after starting. The aluminum cylinder with Suzuki Composite Electrochemical Material (SCEM) coating is built for durability, light weight and efficient heat transfer. A new ECM with higher processing performance and a new high power ignition coil optimize combustion efficiency for increased roll-on performance. 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-Z250's also features a new by-pass hose routing to simplify occasional radiator maintenance. FI indicator (optional part: 36380-28H00) has hour meter function, indicates how many hours engine running. The transmission design achieves a smooth yet solid shift feel. The method of fastening the sprocket attains a quick shift feel. Smart chassis design details include footrest brackets shaped to help prevent mud clogging. The front fork spring pre-load and damping force are fully adjustable, allowing wider range of settings. The Separate Function front Fork (SFF) from Showa, separates the spring and damping tasks.
