## What is Moto Gear Ratio Calculator RPM?

The ultimate motorcycle gearing analyzer for riders, mechanics, and tuning enthusiasts. Calculate exact speed at any RPM, visualize shift points, and compare sprocket combinations — all in one powerful tool.

DIAL IN YOUR GEARING

Enter your gear ratios, primary drive ratio, sprocket sizes, and tire dimensions. Drag the RPM slider and instantly see your speed in any gear on beautifully animated gauges. Switch between km/h and mph with a single tap.

INTERACTIVE GAUGES & GRAPHS

Live RPM tachometer and speedometer with real-time needle animation
Gear Ratio / Shift Point graph showing RPM drop and speed at each shift
Sprocket Spread graph to discover equivalent ratio combinations
Compare Sprockets chart for side-by-side visual analysis
SHIFT & TRACE

Set your shift RPM, hit Trace, and watch the app animate through every gear — recording shift points, RPM drops, and speeds. Choose Shift At or Shift To modes. Adjust animation speed from slow-motion to lightning fast. Enable repeat to loop continuously.

COMPARE EVERYTHING

Toggle Compare Sprockets to add a second front/rear sprocket set. The speedometer shows two needles simultaneously so you can see exactly how a sprocket swap changes your speed in every gear. Compare tire sizes too — see the effect of a different tire diameter on your final drive.
