2017 Suzuki RM-Z450

The 2017 Suzuki RM-Z450 returns with the technology, features and proven performance heritage that make it the choice of champions. A robust yet compact 449cc liquid-cooled four-stroke engine features Suzuki fuel-injection designed especially for motocross use. Racers can choose from different fuel couplers included with the bike to easily tune the system’s fuel mapping trackside, no tools needed. The RM-Z’s Suzuki Holeshot Assist Control system (S-HAC) lets the rider choose one of three modes for the best launch from the starting gate, helping any rider earn the holeshot. Derived from the factory race bikes, the system’s unique modes deliver specific performance depending on the rider’s skill and the gate conditions. The RM-Z450 uses the Showa SFF-Air suspension to deliver reduced weight, increased inner tube diameter, and increased damper rod/piston size. The SFF-Air is made of three chambers, and riders easily change the spring rate with an air pump instead of changing out the coil springs. 2017 Suzuki RM-Z450 Specifications MSRP: $8,749 Engine Engine: 449cc, 4-stroke, liquid-cooled, single cylinder, DOHC Bore x Stroke: 96.0 x 62.1 mm (3.78 x 2.4 in) Compression Ratio: 12.5:1 Fuel System: Fuel Injection Starter: Primary kick Lubrication: Semi-dry sump Drive Train Transmission: 5-speed constant mesh Clutch: Wet multi-plate type, manual release Final Drive: Chain, DID520MXV4, 114 links Chassis Suspension Front: Inverted telescopic, air spring, oil damped Suspension Rear: Link type, coil spring, oil damped Brakes Front: Disc brake, single rotor Brakes Rear: Disc brake, single rotor Tires Front: 80/100-21 51M, tube type Tires Rear: 110/90-19 62M, tube type Fuel Tank Capacity: 6.2 L (1.6 US gallons) Color: Champion Yellow No.2/Solid Black Electrical Ignition: Electronic Ignition (CDI) Dimensions Overall Length: 2190 mm (86.2 in) Overall Width: 830 mm (32.7 in) Overall Height: 1270 mm (50.0 in) Wheelbase: 1495 mm (58.9 in) Ground Clearance: 325 mm (12.8 in) Seat Height: 955 mm (37.6 in) Curb Weight: 112 kg (247 lbs) Warranty: No Warranty
