Suzuki have released the 2013 version of their popular and successful RM-Z450 motocross machine, with a raft of upgrades from nose to tail.

With Todd Waters in the saddle, Suzuki have already enjoyed success with the 2012 spec model in this year’s Monster Energy MX Nationals, and with engine, exhaust, frame and suspension upgrades, the fifth generation model looks set to go even better in 2013.

Starting with the ‘bones’, the RM-Z450's all-new frame is 91 grams lighter with changes to the frame head, rails and down tube and a refined seat rail for rigidity and balance, contributing to increased stability and better handling.

Overhauling the RM-Z450's 449cc, 4-stroke, liquid cooled, DOHC, 4-valve, fuel-injected engine has delivered idle-to-redline thrust that Suzuki describe as “phenomenal”, with increased acceleration, faster throttle response and broader mid-range power and torque.

Developed and tested by factory race teams, the all-new piston is 13 per cent lighter and the piston pin has a Diamond-Like Carbon (DLC) surface treatment, which increases durability and lowers friction. A new intake camshaft and updated electronics have also been fitted to be in harmony with the new engine internals.

The 2013-spec RM-Z450 also features an all-new ECM with higher processing performance that delivers increased power, with a new ignition coil resulting in optimised combustion efficiency and enhanced roll-on performance.

To fine-tune fuel preferences to suit track conditions, two couplers are enclosed allowing the rider to easily change fuel settings between three fuel maps (lean, standard and rich) with the rich-lean coupler relocated for easier access and change without tools.

The redesigned exhaust system meets new FIM sound control regulations, a key goal of Suzuki engineers, thanks to a 50mm extension of the exhaust pipe and redesigned internal muffler parts, increasing bottom to mid-range power and torque, without compromising engine performance.

The 2013 RM-Z450 is equipped with an all-new race-bred 48mm Showa Separate Function Fork containing the spring on the right leg, while the left leg incorporates the cartridge assembly to manage damping, with the result being less friction, increased damping and an overall weight saving.

Finally, all-new aggressive graphics accentuate the RM-Z450's traditional black/yellow livery and stylish new two-tone radiator shrouds.
