- Cluster - loose gear (same ratio as) % rise
- 1st Gear = 11-50 (same as LI 150)
- 2nd Gear = 14-41(same as LI 150) 55% rise from 1st
- 3rd Gear = 16-39 (same as LI 125) 20% rise from 2nd
- 4th Gear = 18-36 (same as GP 200) 22% rise from 3rd
- Advantages of this Casa close-ratio gearbox are :
- Close, even ratio jumps of around 20% from 2nd to 3rd and from 3rd to 4th
- The same final drive ratio in 4th gear as a GP200 gearbox.
- Top gear will give approx. 9.43 mph per 1,000rpm with 18×47 sprockets.
The last point is important because it means that you’ll need to run a big front sprocket (18T or more) with most tuned engine conversions.
