What Is Motorcycle Power-to-Weight Ratio?
The motorcycle power-to-weight ratio expresses how much power a bike produces relative to its mass — calculated by dividing engine output (hp or kW) by the bike's wet weight (kg). A higher ratio means quicker acceleration and better overall performance.
Wet Weight vs Dry Weight
Always use wet weight (with all fluids including fuel) for accurate comparisons. Manufacturers sometimes list dry weight which excludes fuel and oil — this flatters the ratio on paper but doesn't reflect real-world performance. When in doubt, add 15–20 kg to the dry weight figure.
