Product Description
Make your CSC TT250 more relaxed at sustained road speeds. The CSC-1114 45-tooth rear sprocket replaces the original 50-tooth sprocket with substantially taller final-drive gearing for riders who prioritize lower cruising RPM.
With the stock 17-tooth front sprocket, changing from the original 50T rear sprocket to this 45T sprocket makes the final-drive gearing approximately 10% taller. At the same road speed, engine RPM is approximately 10% lower than with the stock 50T sprocket.
- 45-tooth rear sprocket for the CSC TT250
- Designed for the TT250's 428 drive chain
- Dished construction provides the required sprocket offset without separate loose spacer washers
- Works with the stock-length TT250 chain
- Approximately 10% lower cruising RPM compared with the stock 50T rear sprocket
- About 4.3% lower cruising RPM than the 47T option at the same road speed
Which TT250 Rear Sprocket Should I Choose?
| Rear Sprocket | Best For | Gearing Change |
|---|---|---|
| Stock 50T | Low-speed riding and original gearing | Stock |
| 47T CSC-1113 | Balanced street and cruising use | About 6% lower RPM |
| 45T CSC-1114 | Lower cruising RPM and sustained road speeds | About 10% lower RPM |
Want the greatest cruising-RPM reduction? Choose the 45T. It is the more street-oriented option of the two and gives the TT250 noticeably taller gearing than either the stock 50T or 47T sprocket.
If you want a more balanced compromise between stock gearing and lower cruising RPM, consider the CSC-1113 47-tooth rear sprocket instead.
The 45T sprocket provides less rear-wheel torque multiplication than the stock 50T or 47T setup. Actual maximum speed depends on engine output, rider/load, terrain, wind and other conditions; this sprocket does not guarantee a specific top speed.
