CB750F with GSXR750 Front End
« on: July 09, 2014, 01:49:26 PM »
Hey there!

Can anyone point me in the right direction for some information on this swap?  I saved a doomed 75 CB750F from certain death and have since been able to start piecing together parts for the build I hope to do. I have another 75 that I am restoring, but for this one I want to go wild.

I have acquired a '06 (I THINK) GSXR750 front end (minus wheel) and had been planning to mate this to my 750. I have seen this done a number of times but I am having the darndest time piecing together the steps to take for this (especially step 1 being what do I need the machine shop to make me).

Any input is valued!

Thanks!

Www.cognitomoto.com

Devin has custom hubs machined to swap into fit the stock dimensions from the GSXR but still run spokes. He also offers top clamps, or a new adjustable triple to allow you to select 1 of 3 different offsets.

He's got a number of ready-to-go parts to make this swap as bolt-on and bulletproof as possible. Even sells the tapered bearings and replacement stems.

If I weren't on the other side of the country, I would immediately buy you both a beer.  Thank you!
