Chassis Features

• A tubular steel frame with aluminum beam swingarm provides class-leading performance on the track, especially in the corners. Designed for rigidity, durability, and straight-line performance, the frame features large diameter tubing in key areas and a large front reinforcement plate.
• The Showa 37 mm inverted-style front fork is completely adjustable for rider weight, style, and ability. The fork features a cartridge system with fully adjustable rebound damping and 20-way adjustable compression damping (also included are guards to protect the inner fork tubes). The fork legs have 275 mm (10.8 inch) of travel.
• The Showa large diameter rear shock absorber is valved to produce a plush feel and is resistant to bottoming. The shock provides 277 mm (10.9 inch) of wheel travel and features adjustable compression and rebound damping force adjustment.
• A twin-piston caliper front brake with 220 mm (8.7 inch) large-diameter disc and a rear brake with 200mm (7.9 inch) disc to provide excellent braking performance.
• The light, narrow-diameter front and rear brake hoses improve feel and feedback to the rider. The front hose is routed behind the fork leg, eliminating the need for a brake hose cover.
• A rigid rear brake caliper provides reliable braking performance and long pad life, and is easy to maintain. The caliper’s plastic guard reduces the possibility of damage and saves weight.
• The forged aluminum alloy rear brake pedal is light and strong, while providing the rider accurate braking feel.
• High-quality footpegs are made of cast chrome-molybdenum steel, instead of stamped steel, which makes them more durable with better grip.
• Champion Yellow bodywork with graphics design, yellow rear fender, plus black fork protectors and guards provide a professional race look.
• Each side of the color seat has textured surface for better knee gripping.
• The RM85's wheel sizes meet AMA 85cc class regulations (Front: 70/100-17; Rear: 90/100-14).

Engine Features

• The high-revving 84.7cc, two-stroke, liquid-cooled, reed-valve, single cylinder engine has a bore and stroke of 48.0 mm x 46.8 mm.
• The cylinder features Suzuki Composite Electrochemical Material (SCEM) for durability, low weight, and effective heat transfer for superior class performance.
• The exhaust valves are made of aluminum to best match the expansion rate of the cylinder, improving sealing for better engine performance.
• The exhaust valve governor and actuator help provide good throttle response and overall tractability.
• Precise Keihin PE28 carburetor provides smooth throttle response and is designed for simplified maintenance and tuning.
• Digital CDI mapping helps create strong engine performance at high rpm.
• The large-capacity radiator provides efficient engine cooling at all engine speeds.

Transmission Features

• The RM85 is equipped with a smooth-shifting, six-speed transmission and a precise rack-and-pinion activated clutch.
• The long clutch lever makes it easy to accurately locate and work the engagement point during starts and when driving off corners.
• This durable transmission features a refined shift mechanism with a strong detent spring and needle bearing on the left side of the shift drum.
• A knurled shift-pedal tip delivers excellent grip and shift feel for precise gear selection.
