2013 Suzuki RM-Z450

Posted on by  

The Suzuki RM-Z450 is around for quite some time now and during its life has received a lot of awards thanks to its first class performances.

Needless to say that the 2013 model moves this heritage further and continues to deliver modern technologies and solid performances.

The bike is built around a 449cc, 4-stroke, liquid-cooled, single cylinder, DOHC engine that sends its power to the rear wheel through a redesigned 5-speed constant mesh transmission. Thanks to its reshaped shift cam, stopper spring and drive shaft, the transmission offers more precise shifts as well as a better general response.

The motorcycle’s backbone is represented by a twin spar aluminum frame especially engineered to offer great rigidity at high speeds.

The Suzuki RM-Z450 is offered with a starting price of $8,699.

Overview

Suzuki RM-Z450

The Suzuki RM-Z450 gives you the power to dominate the competition.

The Best just got Better! The 2011 and 2012 RM-Z450 both took home Cycle World’s “Best Motocrosser” in its annual “Ten Best Bikes” awards! The 2013 looks to continue this tradition of being the best.

Following the 2011 RM-Z450’s sweep in the award two years prior, Cycle World praised the 2012 model’s powerful engine, smooth throttle response and excellent handling capabilities that made it the clear winner in this year’s awards.

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!

Champions Choose Suzuki...and Suzuki supports future champions! In addition to all the high-tech features and race-winning performance of the 2013 RM-Z models, Suzuki offers the best amateur racing program around!

Get an edge on the competition by finishing out the 2012 contingency year on a Champion Approved 2013 RM-Z450. American Suzuki will be offering millions in contingency for 2013 at events nationwide!

Key Features

Suzuki RM-Z450
  • 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.
  • Redesigned 5-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 (Part no. 36380-28H00).
  • 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.

Engine Features

Suzuki RM-Z450
  • 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.
  • Compact and lightweight 4-stroke, 449cc, 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.

Transmission Features

Suzuki RM-Z450
  • Redesigned 5-speed transmission with reshaped shift cam, stopper spring and drive shaft results in more solid shift feel, enabling more precise gear shift operation.

Chassis Features

Suzuki RM-Z450
  • 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.
  • Front fork inner tube diameter is increased from 47mm to 48mm, 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.
