Got mine from gas bike.didn't know it was a knockoff. How can you tell. The price was good
I don't know how one can tell if its a knock off. Check the forum for info.
Anyhow I did order one of the authentic painted ones and it was very nice paint job ( I was surprised at the quality). and came bubble wrapped as I requested. Just note these have the double pull brake tabs for 28 and 26 inch tires plus are said to have longer chain stays. I can confirm the pedestal is drilled only to fit the genuine Grubee motor that has a wider case. as the holes are wider apart for the stud spacing. It Wont fit my PK80 motor without me drilling new holes. That said the paint and clear coat were blemish free, saving me 135 bucks at the powder coater on this build.
Also just remembered the cap is the tall black plastic type ( its a way better fit now) whereas the one I got previously (probably a knock off) had a steel cap that wouldn't close until I ground the seal down a ton on my bench grinder and took a jewelers file to the gas cap opening to smooth it out. I had a dickens of a time getting a petcock to fit also. Got one from Mz and it worked fine. I am going to use the extra brake bungs for a lay back seat supports...
