Chassis Features

  • A tubular steel frame with aluminum beam swingarm provide 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
  • SHOWA 37 mm inverted front forks are completely adjustable for rider weight, style and ability. The forks feature 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 forks have 275 mm (10.8-inches) of travel
  • A SHOWA large diameter rear shock absorber is valved to produce a plush feel and resistance to bottoming. The shock provides 277 mm (10.9-inches) of wheel travel and features adjustable compression and rebound damping force adjustment
  • A twin-piston caliper front brake with 220 mm (8.7-inches) large-diameter disc and a rear brake with 200 mm (7.9-inches) disc to provide excellent braking performance
  • The light, narrow-diameter front and rear brake hoses improve feel and feedback to the rider. The font hose is routed behind the fork leg, eliminating the need for a brake hose cover
  • A rigid rear brake caliper provides reliable braking performance, 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
  • Each side of the new color seat has textured surface for better knee gripping
  • The RM85's wheel sizes meet AMA 85 cc class regulations (Front: 70/100-17; Rear: 90/100-14)
  • New competition inspired body panel colors, graphics and seat color

Engine Features

  • Digital CDI mapping helps create strong engine performance at high RPM.
  • The high-revving 84.7 cc, 2-stroke, liquid-cooled, reed-valve, single-cylinder engine has a bore and stroke of 48.0 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
  • 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 plus 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 driving off of 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
