Suzuki 2022 RM85 Dirt Motorcycle – Features and Specs

Key Features

At any RPM, an 84.7cc, 2-stroke liquid-cooled engine generates steady power. Riders can accelerate out of every turn with a six-speed transmission’s precision shifting and clutch action—the lightest weight in its class and agile handling. Fully scalable Showa piggyback reservoir rear shock and inverted fork. Includes the potential to get track-side assistance and Suzuki contingency.

Engine Features

The size and stroke of the 84.7cc, two-stroke, liquid-cooled, reed-valve engine are 48.0 mm and 46.8 mm, respectively. Suzuki Composite Electrochemical Material (SCEM) is used in the cylinder for its durability, low weight, and efficient heat transmission for best-in-class performance. To better match the cylinder expansion rate and improve sealing for improved engine performance, the exhaust valves are constructed of aluminum. The governor and actuator for the exhaust valve contribute to the smooth throttle response and overall tractability. Smooth throttle response is provided by the precise Keihin PE28 carburetor, which is built with easy maintenance and tune in mind. Strong engine performance is facilitated by digital CDI mapping at high rpm. At all engine speeds, the large-capacity radiator effectively cools the engine.


The RM85 has a precision rack-and-pinion operated clutch and a six-speed gearbox with seamless shifting. It is simple to precisely identify and manage the engagement point during starts and while accelerating out of bounds, thanks to the long clutch lever. With a powerful detent spring and needle bearing on the left side of the shift drum, this dependable transmission has a well-designed shift mechanism. For proper gear selection, a knurled shift pedal tip provides a superb grip and shift feel.

Chassis Features

Class-leading track performance is provided by a tubular steel frame with an aluminum beam swing arm, particularly in the bends. The frame has oversized diameter tubing in strategic locations and a sizable front reinforcing plate since it was built to be sturdy, durable, and operate well in straight lines. The Showa 37mm inverted front fork has a wide range of adjustments for rider ability, weight, and style. The fork has a cartridge system with 20-way programmable compression damping and fully adjustable rebound damping. The travel distance of the fork legs is 275 mm (10.8 inches). The Showa big diameter rear shock absorber is bottoming-resistant and has valves that give a velvety feeling. The shock has adjustable compression and rebound damping forces and offers 277 mm (10.9 inches) of wheel travel.

A rear brake provides excellent stopping performance with a 200mm (7.9-inch) disc, and a twin-piston caliper front brake with a 220mm (8.7-inch) large-diameter disc. The front and rear brake hoses’ low weight and small diameter enhance the rider’s sense of touch and feedback. There is no need for a brake hose cover since the front hose is run beneath the fork leg. A stiff rear brake caliper offers dependable stopping power, extended pad life, and ease of maintenance. The plastic protection on the caliper lessens the risk of injury and sheds weight. The rear brake pedal is made of forged aluminum alloy, which is light and sturdy yet gives the rider a unique braking sensation. Instead of being stamped, high-quality foot pegs are constructed of cast chrome-molybdenum steel, which provides them with superior grip and increased durability.

A professional racing appearance is provided by the Champion Yellow bodywork, RM-Z style graphics design, and black fork covers and guards. The new color seat includes a textured surface on either side for a more excellent knee grip. The RM85’s wheels (front: 70/100-17; rear: 90/100-14) comply with AMA 85cc class requirements.
