Just trying to date this - know it's tricky.

I'm thinking '81 or possibly '82? What do you think?

Chain tensioners, braced tubes behind BB, two plate brake bridge, Serial is 1890.

i'm no CBR expert but that is cool!

Thanks man. I'm stoked at the workmanship of these things - machined headtubes and BB, awesome welds... Quality USA workmanship.

CBR's were way ahead of their time. Very nice!

Sweet Cooks mate!!! One to build up & take to Knox...hehe

If that's a Cooks seat clamp be ready for your inbox to flood

Naah Cheez - a Helix.

Mick - yeah - my Knox build I reckon.

Props to Claude (Mastertint).

She's an '82.

Thanks mate.

if your gonna date it, are you gonna take it for dinner and drinks? hahaha, just kidding. nice looking bike, Kurt. that should be a sweet build.

COOK Bros.!!!!!!!!!!
