2018 Honda CBR300RAJ
Stock Image: Non-ABS, Prior Year Model Shown
- High performance: The 286 cc single-cylinder engine boasts dual overhead camshafts driven by a Hy-Vo-type silent chain, forked roller rocker arms, a compact four-valve cylinder head, a counterbalance shaft for smoothness, and liquid cooling for optimum performance and durability.
- Easy inspection & maintenance: Shim-style valve adjustment allows easy inspection and maintenance, although with a recommended inspection interval of 48,000 km, you'll ride a long, long time between any needed adjustments.
- Light & compact: The light and compact engine contributes to the CBR300R's impressive power-to-weight ratio, allowing it to compete with twin-cylinder bikes of similar displacement.
- Stacked design: The engine countershaft sits lower than the mainshaft in a “stacked" formation to reduce the engine's front-to-rear dimensions.
- Easy city or highway ride: The engine produces a remarkably broad torque curve for strong low-rpm performance, and peak horsepower kicks in at 8,500 rpm - well below redline. This wide spread of power makes the CBR300R easy and confidence-inspiring to ride, in both stop-and-go situations and on the highway, while also returning impressive fuel economy.
- High-performance engine: The crankshaft runs in plain bearings for quieter operation and the big end of the connecting rod spins in a needle bearing, both contributing to the engine's high-performance credentials.
- Enhanced rider comfort: A gear-driven counterbalance shaft helps quell engine vibration for enhanced rider comfort. It's located so close to the crankshaft that the balancer weight passes between the two crank weights to keep the engine as compact as possible while improving mass centralization.
- Quick acceleration for an edge: The six-speed transmission works in concert with the engine's broad power delivery to produce quick acceleration plus excellent fuel economy during highway cruising. Final drive gearing is also taller than the previous model (CBR250R) to further improve efficiency at highway speeds.
- Optimal performance in any weather: Honda's Programmed Fuel Injection (PGM-FI) continuously monitors several variables to ensure the correct fuel mixture for the current riding and atmospheric conditions. The system delivers optimal performance and remarkably crisp throttle response over a wide range of operating conditions, plus improved fuel economy. The PGM-FI system also incorporates an Idle Air Control Valve (IACV) to smooth responses to small changes in throttle position.
- Impressive handling & comfort: Diamond-shaped twin-spar steel frame plus a 37 mm front fork and Pro-Link single-shock rear suspension provide sporty, confident handling and a comfortable ride.
- Maneuver with confidence: Curb weight of only 161.9 kg (357 lbs.) gives the CBR300R outstanding maneuverability and helps instill rider confidence.
- Long-distance comfort: Sporty ergonomics create a balanced seating position for optimum control without compromising long-distance comfort.
- Handles like a bigger bike: Full-sized 17-inch cast wheels with a 110/70 - 17 front tire and a 140/70 - 17 rear tire provide big-bike feel, grip and handling traits.
- Aggressive Look: The CBR1000RR inspired bodywork features dual headlights and colour-matched undercowl. The unmistakable CBR fuel tank and steeply raked tail complete the aggressive look.
- Information at a glance: Multi-function digital instrument panel includes speedometer, tachometer, engine temperature display, fuel gauge, clock, odometer and trip meter.
- Easy balance at stops: A narrower, reshaped seat makes it easier to reach the ground.
- Passenger confidence: Grab rails on the tail section are designed to fit gloved hands, giving passengers a dedicated handhold while riding two-up.
