Suzuki RM-Z450

Suzuki Australia is preparing to unleash the ultimate four-stroke weapon - the latest incarnation of the all-conquering RM-Z450.

Featuring a number of notable updates, the supremely balanced RM-Z450 offers strong, controllable power and extremely lightweight handling for breathtaking acceleration and total rider confidence.

Remarkably easy to ride, the Suzuki RM-Z450 is loaded with advanced technology including the Suzuki Advanced Sump System, the Suzuki Active Vent System, lightweight and durable titanium valves, hollow billet camshafts and much more.

The updated 450cc, 4-stroke, liquid-cooled, DOHC, 4-valve engine features a lightweight design with the emphasis on broad power delivery.

Re-shaped intake ports for optimal efficiency offer increased engine performance at low-to-mid rpm.

A durable forged-aluminium piston with oil-retaining grooves reduces friction and wear, while the aluminium cylinder bore and oil control rings are electro-plated for increased durability and heat transfer.

Equipped with an NGK iridium spark plug for better combustion, the RM-Z450's combustion chamber has been re-designed to provide increased engine output.

The Suzuki Active Vent System reduces crank chamber pressure and enhances piston ring seal performance, while the Suzuki Advanced Sump System permits low crankshaft placement for reduced engine height and low centre of gravity.

The RM-Z450's new scavenging pump provides increased lubrication and improved durability, combined with reduced mechanical losses at the crankshaft.

For easy maintenance, the RM-Z450's oil strainer is now easily overhauled without separating the crankcases.

Featuring a Keihin FCR40 carburetor with hot start system and throttle-position sensor, the RM-Z450 incorporates an automatic decompression system for easy kick starting.

Updated carburetor settings and a lightweight exhaust system with titanium head pipe, large-capacity stainless-steel secondary pipe and aluminium muffler also enhance the power of the new RM-Z450.

Retaining the four-speed transmission for weight reduction and compact engine size.

Re-designed radiator shrouds offer the RM-Z450 improved cooling efficiency and an aggressive new look, while the sidecovers are now vented for maximum airflow.

Designed for optimum strength, rigidity and weight the updated aluminium-alloy, twin-spar frame features thicker lower tubes and thinner tank rails for unmatched cornering performance.

Featuring a re-shaped pivot section and shorter main section, the new aluminium swingarm with tapered beam incorporates a cast-aluminium cross beam to improve straight-line performance.

Suspension settings have also been updated to match the all-new frame including Showa cartridge-style front forks with 47mm inner tube, offering 22-way compression damping, 20-way rebound damping and 310mm of wheel travel.

The Showa rear shock absorber with its large 50mm piston and 18mm inner rod provide increased oil flow and stable damping performance, while the RM-Z450 rear suspension linkage allows smooth movement for improved rear wheel traction.

Front and rear brake discs now feature a round-hole design for reduced weight, with the compact 240mm rear disc brake sporting a lightweight caliper body.

Specially-designed Bridgestone tyres with a large contact patch offer improved traction and acceleration while aluminium wheels, spokes and spoke nipples are designed for the best balance of weight, rigidity and overall wheel strength.

Renthal tapered aluminium handlebars with Renthal-labelled handlebar pad are included as standard.

An all-new seat with new textured side panels offers increased knee grip, plus lightweight titanium serrated footpegs are included for maximum strength and improved grip in all riding conditions.

Expected to arrive in Australia in September, the RM-Z450 will be available in Suzuki's Champion Yellow sporting updated aggressive graphics. The suggested retail price is to be announced.
