Chain slack checks with less guesswork
The BPA Racing Slack Setter uses clear Too Loose / OK / Too Tight indicators to help you check your chain slack against a calibrated reference for your motorcycle.
Calibrate first. Then check.
- Set your chain slack according to your motorcycle manufacturer’s recommended measurement and procedure.
- Calibrate the Slack Setter to that setting, following the supplied instructions.
- Check the indicators during subsequent checks and adjust your chain according to your motorcycle manual when needed.
Use your motorcycle’s specified chain slack and checking procedure instead of relying on a general “three-finger” estimate.

Built for regular chain maintenance
The BPA Racing Slack Setter combines a stainless-steel body with a spring-loaded mechanism and clear visual indicators. It is designed to be reused as part of your motorcycle's chain maintenance routine.
For chain-driven motorcycles
Designed for motorcycles with chain drive, including road, touring, adventure, enduro and motocross models.
Keep up with regular maintenance
