| Formula To Calculate MPH: |
RPM ÷ GR x SC ÷ 12 x 60 ÷ 5280 = MPH @ 1:1 Clutch RatioGR = Gear Ratio (divide top sprocket into bottom sprocket)
SC = Sprocket Circumference (number of teeth x track pitch) |
| 7T – 2.52″ Pitch |
= 17.64 SC |
| 8T – 2.52″ Pitch |
= 20.16 SC |
| 9T – 2.52″ Pitch |
= 22.68 SC |
| 10T – 2.52″ Pitch |
= 25.20 SC |
| 7T Convolute – 3.29″ Pitch |
= 23.03 SC |

= Pitch |
CD = Center Distance (Drive Shaft to Jackshaft Centers)
TS = Top Sprocket
BS = Bottom Sprocket
Round number up to even number for proper pitch |
