Dirt Bike Horsepower Calculator

Convert crank torque and RPM into horsepower and kilowatts. Use a dyno torque reading or a manufacturer peak-torque figure.

Inputs

Peak or measured engine torque

Live

  • Horsepower

    61.5hp

  • Kilowatts

    45.86kW

  • Metric horsepower

    62.35PS

  • Torque

    51.52N·m

Formula

HP = (torque × RPM) / 5252 · kW = (N·m × RPM) / 9549

5252 is the imperial conversion constant. Peak horsepower almost never occurs at the same RPM as peak torque.

Torque
Back-solve torque from horsepower and RPM. Useful when a spec sheet lists peak HP but not the matching torque figure.
Power-to-Weight
Compare bikes the way they actually feel: horsepower against wet bike weight plus rider. Higher hp/lb (and W/kg) means a snappier chassis.
Top Speed
Estimate gearing-limited top speed in high gear at a given RPM. This is the speed the sprockets and tire will allow — not a drag-strip prediction.
0–60 Acceleration
A power-limited estimate of 0–60 mph time from horsepower, ready-to-ride weight, and drivetrain loss. Ignores wheelie, traction, and aero.
