M2R RS-R 300 — Built to Hit Harder
Forget “entry-level.” The RS-R 300 is a full-fat, water-cooled weapon that out-punches typical 300-class trail bikes with real race hardware and big-bike ride feel.
Smooth, torquey power. The Zongshen NB300 single (4-valve, SOHC, balance shaft) is fed by a Nibbi PWK34 Sports carb for instant snap. Hit the button—electric start with lithium battery—and go. Final drive is tough #520 chain with 13/52 gearing to keep you in the meat of the torque.
Chassis you can trust. A high-strength cradle frame and alloy integrated swingarm carry a 54/60 mm adjustable USD fork (310 mm stroke) and a tuned rear shock for planted traction. 7116-alloy 21/18 rims wearing M2R soft-compound tyres plus serious stopping from a 260 mm wave front disc with dual-piston caliper and a 220 mm rear, keep the pace hot and controlled.
