Features

Chassis/Suspension

Attractive aluminum twin-spar frame designed for optimum strength, rigidity and weight

Aluminum swingarm with tapered beam design similar to RM250 - features cast-aluminum cross beam to improve straight-line performance

RM250-type rear suspension linkage - suspension load placed on the swingarm instead of the frame to reduce weight, and allows smoother movement of the rear shock and linkage for improved rear wheel traction

New lightweight chain guide design similar to RM125/250 - cutaway design reduces weight

Showa-brand cartridge-style front fork with 47mm inner tube, plus 22-way compression damping, 20-way rebound damping and 12.2 inches. of wheel travel - internal structure similar to RM250

Showa-brand rear shock absorber with large 50mm piston and 18mm inner rod for increased oil flow and stable damping performance

Large 250mm front disc brake designed for reduced weight and high durability - includes Kevlar brake hose for low expansion rate and improved brake lever feel - rotor is mounted at four points instead of six with new-type shouldered bolts for a secure fit and minimal weight

Compact 240mm rear disc brake with lightweight caliper body similar to RM-Z250 - rotor is mounted at four points instead of six with new-type shouldered bolts for a secure fit and minimal weight

New-style wheels, spokes and spoke nipples designed for the best balance of weight, rigidity and overall wheel strength

New-style front and rear wheel hubs designed for reduced weight and added strength - provides more rigid assembly when combined with larger axle, new spoke design and wide wheel bearing pitch

Specially-designed Bridgestone tires with large contact patch for improved traction and acceleration - 90/100-21 front, 120/90-19 rear - wider than competing models without weight increase

Renthal tapered aluminum handlebars with Renthal-labeled handlebar pad - lighter than standard bars - rubber-mounted to reduce vibration

Titanium footpegs designed for high grip and minimal weight

Slim fuel tank shape designed to blend with the seat and radiator shrouds for easy rider movement and weight transition

New-design rear fender and frame covers with fresh air vents for increased air flow to the carburetor airbox

Shouldered aluminum spacers for quick and secure mounting of body work

Engine

Compact 450cc, 4-stroke, liquid-cooled, DOHC, 4-valve engine - lightweight design with emphasis on broad power delivery

Narrow cylinder head design featuring shim-under-bucket valve train with titanium valves for reduced reciprocating mass and more stable high-rpm performance

Lightweight hollow-type camshafts with carburized surface treatment for durability and high lubrication qualities - hollow design further contributes to precise valve operation at all engine rpm

Durable forged-aluminum piston with tin plating and oil retaining grooves to reduce friction and wear

Electro-plated aluminum cylinder bore for increased durability and heat transfer

KeihinTM FCR40 carburetor with hot start system and a throttle-position sensor linked to digital CDI ignition

Lightweight exhaust system with titanium head pipe with large-capacity stainless-steel secondary pipe and aluminum muffler

Automatic decompression system similar to RM-Z250 - simple lightweight system designed for easy kick starting and durable operation

Suzuki Advanced Sump System - semi-dry-sump lubrication system featuring separate crankshaft and transmission oil chambers - permits low crankshaft placement for reduced engine height and low center-of-gravity

Suzuki Active Vent System - one-way reed valve system between crankshaft and transmission to reduce crank chamber pressure and enhance piston ring seal performance and overall engine power

Four-speed transmission for weight reduction and compact engine size - allows clutch to be placed closer to engine centerline to concentrate engine mass and reduces crankcase area required for transmission

Counterbalancer shaft gear-driven off the magneto rotor to reduce engine vibration without adding to engine size or weight
