The Suzuki RM-Z450 gives you the power to dominate the competition. For 2013, the RM-Z450 is redesigned to give you an even greater edge. With a thoroughly refined engine, it develops exceptional power from idle to redline and incredibly crisp throttle response. It also features the innovative new separate function front fork (SFF) from Showa. The new front suspension works with an updated twin-spar aluminum frame engineered for an optimum balance between rigidity and high-speed traction, providing you with incredibly precise handling and smooth performance on the toughest tracks. The new RM-Z450 - it puts championship-winner performance in your control to reach the top of the podium!

Key Features
 In 2011, Suzuki introduced the coupler system to the RM-Z450. The 2013 RM-Z450 uses this innovative design, which consists of three couplers that allow you to quickly adjust the fuel setting to suit riding conditions. One coupler contains the stock settings, a second is for a richer fuel setting than the stock setting and the third is for a leaner setting.  
 All-new Showa separate function front fork (SFF) separates spring and damping functions. The right leg holds the spring, while the left leg incorporates the cartridge assembly to manage damping. The SFF design reduces friction, increased absorption performance and is lighter weight resulting in remarkably smooth performance over a variety of track conditions.  
 Redesigned five-speed transmission with reshaped shift cam, stopper spring and drive shaft results in more solid shift feel, enabling more precise gear shift operation.  
 Riders can now track engine-operating time and better manage maintenance intervals using the optional FI indicator.  
 Compact and lightweight four-stroke, 449 cc, fuel-injected, DOHC engine provides extraordinary torque for awesome acceleration from idle to redline, with incredible high-rpm power.  
 The newly designed piston, piston pin and connecting rod are developed with use of Finite Element Method (FEM) analysis. The new piston is 13 percent lighter without any compromise to strength and rigidity.  
 The new piston pin has Diamond-Like Carbon (DLC) surface treatment for less friction and increased durability. The new design reduces mechanical loss and helps the engine produce quicker throttle response.  
 Intake cam timing and amount of lift has been modified for smoother power delivery and control.  
 Aluminum cylinder, with Suzuki Composite Electrochemical Material (SCEM) coating, is designed for durability, light weight and efficient heat transfer.  
 An advanced battery-less fuel-injection (FI) system features a 12-hole fuel injector and progressive throttle linkage for instant throttle response.  
 A new ECM with higher processing performance and a new high power ignition coil optimize combustion efficiency for increased roll-on performance.  
 Redesigned muffler internal parts, bottom-to-mid range power and torque are increased, resulting in improved performance without losing top end. The new muffler body now uses conventional bolts in end cap instead of rivets to simplify the replacement of the glass wool packing in the muffler.  
 Redesigned five-speed transmission with reshaped shift cam, stopper spring and drive shaft results in more solid shift feel, enabling more precise gear shift operation.  
 Front fork inner tube diameter is increased from 47 mm to 48 mm, results in optimized stability and absorption. The spring pre-load is now adjustable, which allows a wider range of adjustment for all level of riders.  
 The frame and seat rail have been refined for optimized rigidity balance. The result is an ideal balance of nimble handling and stability.  
 To maintain the RM-Z's renowned handling performance, each bike's rear suspension features a Showa piggyback shock with setting changes and adjustments to best match with the increased engine performance and front forks changes. The design allows enhanced suspension performance for a wider variety of riders.
