Estimates, not advice
RideCalc outputs are estimates based on nominal data, simplified formulas and the inputs you enter. They are for general information and comparison, and are not mechanical, safety, legal or financial advice.
Real-world results vary
Sprocket calculations describe theoretical gearing changes, not actual acceleration or top speed. Tyre calculations use nominal dimensions; actual rolling circumference depends on the tyre model, load, pressure and wear. Speed estimates assume a baseline and are not precise speedometer calibration.
Check before changing your setup
Verify fitment, specifications, tolerances and relevant limits with the vehicle and part manufacturers or a qualified professional. Check matters such as tyre compatibility, clearances, chain length and adjustment range before buying or fitting parts. A calculator result does not establish that a modification is safe, road legal or approved for your vehicle.
