Approximately 40 horsepower from the engine (roughly 29–31 kW). Rear-wheel output is typically lower and varies with exhaust, altitude, and tuning.
The Honda CBR300RR is a compact, high-revving sport bike that relies on a 286cc powerplant designed for strong high-end performance. Official figures can vary by market and year, and horsepower can refer to engine output or wheel output measured on a dyno. The following breakdown highlights typical numbers you might encounter across versions.
Power figures by market and year
Below is a concise breakdown of typical engine (crank) horsepower and a note about wheel horsepower for context.
- Engine horsepower (crank): typically around 39–42 hp (29–31 kW) at peak, depending on market and year (roughly 9,500–12,000 rpm).
- Rear-wheel horsepower (dyno): commonly about 33–38 hp, depending on exhaust setup, air intake, gearing, and altitude.
These figures illustrate the common range you might see published or measured; your actual bike may differ slightly due to tuning, emissions configurations, or model year.
Crank vs wheel horsepower explained
Crank horsepower is the engine output reported by spec sheets or dynos, while wheel horsepower is what the rear wheel delivers to the road after drivetrain losses. For a 300cc sport bike, wheel horsepower is typically 15–20% lower than crank horsepower.
What factors influence the ratings?
Exhaust design, intake configuration, altitude and temperature, and how the bike is dyno-tested all influence the published numbers. Always check the specific spec sheet for your market and year.
Summary
The CBR300RR typically delivers around 40 hp at the engine, with rear-wheel output in the low-to-mid 30s hp depending on configuration and conditions. For precise figures, consult the exact model-year specifications or a trusted dyno result for your market.
