Cooling notice: Lower cruising RPM also means the OEM engine cooling fan rotates more slowly. Depending on engine specification, vehicle load and how the vehicle is used, additional oil cooling may be required.
Calculation note: Results are intended as a gearing comparison guide. Actual road speed and RPM can vary slightly with tyre manufacturer, tread depth, tyre pressure, load and drivetrain tolerances.
