Thinking about a sprocket swap? See exactly what it does to your gearing, your rpm and your speed, before you spend a dollar. This is the first of the Motozmo rider tools, free like everything here.

One speed you know

What changes

3.00Current ratio (rear / front)
3.21New ratio
5,360RPM at 60 mph with the new setup
56.0MPH at 5,000 rpm with the new setup
+7.1% shorter gearing

How it works: gear ratio is rear teeth divided by front teeth. A bigger ratio means shorter gearing, a smaller ratio means taller gearing. The rpm and speed figures scale from the one reading you give it, so use a speed and rpm you have actually seen on your own bike, in the same gear, for both setups.

Keep the rhythm

Service Intervals

The maintenance rhythm every rider should keep.

  • Every ride

    Tire pressure & tread · lights · brake lever feel

  • Monthly

    Chain slack & lube · oil level · coolant level

  • Every 6 months

    Brake fluid · air filter check · battery terminals

  • Yearly

    Spark plugs · valve clearance · full fluid swap

From the workshop

Most “dead battery” no-starts are just corroded terminals. Clean them before you buy anything.
