2021 Suzuki RM-Z250
The choice of wise professionals and privateers everywhere, the 2021 RM-Z250 is ready for battle. The agile RM-Z250 combines the sleek, race-ready appearance of the RM-Z450 with a versatile engine and responsive chassis to deliver superior performance. Using Suzuki’s “RUN, TURN and STOP” philosophy, factory engineers have made the RM-Z250 a formidable competitor.
The RM-Z250 has always set the standard as the best handling 250 on the track. Fed by a dual injector EFI system, a center-port cylinder head and an AMA-compliant exhaust, the RM-Z250’s engine delivers strong, usable power through the entire rev-range.
The twin-spar aluminum frame and hydro-formed swingarm carry a KYB-supplied suspension that includes a coil spring fork and a shock with four-way damping force adjustment. Strong brakes and ergonomically shaped bodywork that helps keep the rider in control as the RM-Z250 carves up the racetrack.
Tuning the fuel injection and ignition for maximum performance is easy thanks to Suzuki’s smartphone-based MX-Tuner 2.0 and proven fuel-coupler system. Suzuki’s Winning Balance is on display with the 2021 RM-Z250 as it maintains its own high standard for cornering performance.
Features may include:Superb Engine Performance
- Center-port cylinder head increases output and throttle response
- Dual fuel injector system boosts high rpm power
- Traction management system helps the bike hook up
- Suzuki Holeshot Assist Control (S-HAC) gets you out front
- ENGINE
Fitted with a center-port cylinder head, the fuel-injected, 249cc, liquid-cooled, four-stroke, four-valve, DOHC engine remains proven and reliable.
The engine delivers strong peak power and superb throttle response through the entire rev range.
The cylinder head features a refined intake port shape and finish that fine-tunes the fuel/air charge into the combustion chamber to increase engine output.
- TRANSMISSION & DRIVE
The five-speed transmission's second gear ratio and overall final ratio matches the engine’s stronger output for outstanding acceleration and top speed.
True to Suzuki transmission standards, the gear shift operation is smooth and precise. Carefully designed parts like the precisely machined shift cam and corresponding gears create a transmission a racer can rely on.
The multi-plate, wet-clutch uses a rack-and-pinion clutch release mechanism for precise feel of the engagement and disengagement points while riding.
- CHASSIS
The RM-Z250 features a frame and swingarm design that continues Suzuki’s reputation for creating the best-handling motocross motorcycles.
The aluminum alloy, twin-spar frame combines cast and extruded sections to achieve superior front-and-rear weight distribution, while balancing strength and weight.
The 2021 RM-Z250 frame is 370 grams (0.8 pounds) lighter but has a 10 percent increase in torsional rigidity as compared to the prior generation frame.
The engine's position in the frame is rotated up so the crankshaft sits higher in the chassis to further the bike’s nimble handling characteristics.
The rear, upper engine mounts are outboard of the cylinder head to increase rigidity and allow a direct intake path to the engine.
The engine mount material is changed to aluminum, rather than steel, for reduced weight.
The swingarm is shaped using an innovative hydroforming process that maintains strength but weighs 0.6 pounds (270 grams).
