You’re asking if it’s possible to install rear disc brakes on your Suzuki Gixxer SF. Well, technically it is possible but we would advice against it for three reasons:
- Third party installed disc brakes don’t offer the same effectiveness as the manufacturer installed ones.
- Cost involved is very high
- Suzuki is on the verge of launching a dic brake variant of the Gixxer SF.
Given the above reasons, the entire procedure of installing disc brakes on your bike is just not worth it.
