Yeah, usually the 90 degree nerf bars started in 05. But that CRG-PTK with the Freeline bodywork was one of the first to use the 90 degree nerfs in 04. My PTK was an 04, but the homlogation tag didn’t say CRG. It also had a slightly different brake system with dual masters and dual calipers for the rear.
I put a clone motor on mine and then sold it right away. That was before 206 got big and I was mainly running tag.
I thought that chassis was always loose in the rear, so I think it would have been a good 206 kart to get freed up with the low horsepower.
