What it does

Edit bike holds the numbers the quick calculators use. Bikes added from the database come pre-filled from the gearing bench library. A hand-entered bike starts from the example bike’s numbers until you change them.

1. Open it

• From the Garage, tap Edit on a bike, or + Enter a bike by hand for a new one.
• The Edit bike card on the hub opens the active bike.

2. Fields

• Profile name, year, make and model.
• Horsepower and torque (lb-ft), bike wet weight (lb), redline rpm and primary ratio.
• Front and rear sprocket now, plus stock front and rear (the calculators compare against stock).
• Chain size (420, 428, 520, 525, 530 or 630) and stock chain links (the Chain length tool needs this).
• Rear tire width, aspect and rim.
• Gear ratios from 1st to top, separated by commas (at least 3).

3. Save

• Tap Save bike. The app checks horsepower, weight, redline, primary ratio, sprockets and the gear ratios, and tells you if one is missing.
• Saving makes the bike active and takes you back to the Garage.

Tips

Use your owner’s manual or a factory spec sheet for the primary and gear ratios. Count the links on your current chain if you’re not sure of the stock number.
