M2R RS-R 300: A Hard-Hitting, Race-Ready Trail Weapon
M2R has officially launched the RS-R 300, a trail machine aimed squarely at riders who want big-bike performance without big-bike size. Far from an “entry-level” option, the new RS-R 300 arrives loaded with race-grade hardware, serious suspension, and a water-cooled 300-class engine that promises to out-muscle the competition.
Powertrain: Strong, Smooth, and Built for Real Riding
At the heart of the RS-R 300 is the proven Zongshen NB300 engine — a 4-valve, SOHC, balance-shaft-equipped single delivering:
- 25.5 bhp @ 8,500 rpm
- 24 N·m of torque @ 7,500 rpm
A Nibbi PWK34 Sports carburetor provides crisp throttle response, while electric start and a lightweight lithium battery ensure dependable instant ignition. Power reaches the rear wheel through a #520 chain and 13/52 gearing, optimized to keep riders firmly in the torque curve.
A Chassis Designed for Control
The RS-R 300’s structure centers on a high-strength cradle frame paired with an integrated alloy swingarm. Suspension comes via a 54/60 mm fully adjustable USD fork offering 310 mm of stroke, matched with a tuned rear shock for stable traction across aggressive terrain.
Rolling on lightweight 7116-alloy 21/18 rims and M2R soft-compound tyres, the bike is engineered for grip and precision. Braking power is delivered through a 260 mm front wave disc with a dual-piston caliper and a 220 mm rear disc, giving riders full confidence during high-speed trail attacks.
Pro-Grade Components That Raise the Bar
M2R has equipped the RS-R 300 with an extensive list of premium components typically seen on higher-tier machines:
