• New piston oil control rings featuring chrome-nitride coating for improved sealing and reduced friction
• Revised ignition mapping for increased power output especially at low-to-midrange rpm
• Higher final drive ratio, (49/14 to 48/14), for easier power delivery control at all rpm
• Reshaped shift fork guide pins for more positive feeling gear shifts
• Relocated hot-start lever for easier access

NEW CHASSIS

• Modified steering head pipe for improved frame rigidity
• New swingarm with increased main beam diameter for improved traction and straight line stability
• New front fork and rear shock settings for improved cornering and straight line performance
• New rear brake caliper with higher rigidity for increased stopping power and better brake feel

ENGINE FEATURES

• 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
• Lightweight hollow-type camshafts with carburized surface treatment for durability and high lubrication qualities
• 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
• Keihin TM FCR40 carburetor with hot start system and throttle-position sensor
• Lightweight exhaust system with titanium head pipe with large-capacity stainless-steel secondary pipe and aluminum muffler
• Automatic decompression system for easy kick starting
• Suzuki Advanced Sump System permits low crankshaft placement for reduced engine height and low center-of-gravity
• Suzuki Active Vent System - reduces crank chamber pressure and enhances piston ring seal performance
• Four-speed transmission for weight reduction and compact engine size
• Counterbalancer shaft gear-driven off the magneto rotor to reduce engine vibration without adding to engine size or weight

CHASSIS FEATURES

• 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 - allows smooth movement of the rear shock and linkage for improved rear wheel traction
• 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
• 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
• Compact 240mm rear disc brake with lightweight caliper body similar to RM-Z250
• 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
