Cognito GSXR fork swap question
« on: June 09, 2014, 07:08:41 PM »
Looking for the OD of the 2006+ GSXR 600/750 forks ? I have read a few different #'s and not sure which is true ?? Wanting to sorce my headlight bucket / bracket and clip-ons but need the correct OD #.

Is it 50mm upper, tappers down to 48mm lower ???

43mm comes to mind. Have you emailed Devin at Cognito? He will know for certain.

The 500 build in my signature is incorporating the Cognito hub and GSXR front end. The 550 used the stock forks and a Joker triple. I'll be making huge progress on the 500 very shortly as the engine work is just about wrapped up.
