Banjo bolt pressure switch. Size is 10mm x 1.25 pitch. This is ideal for our disc brake conversion rear hubs. This is the size of the GSX-R rear master we use.
These are the best sets out there. Perfect fitment. I am always completely satisfied with parts I receive from Cognito. Customer Service is outstanding.
The Quality and finish of Cognito Moto are second to none. I ordered rearsets and rear foot pegs from them and they are far better than anything else I could find.
