Checkout the new KN250GY & KN200GY-4 + parts diagram.
 

Never could tell for sure where Roketa DB-05 came from until now. The KN200GY-4 is completely identical except for the Engine, it's showing an OHC in the Kayak brand but the Roketa has been coming in with a Zongshen OHV. Probably a production run just for Roketa ?

The 250 looks like it may be a decent bike as they are saying it assembled with the Zongshen 250 Engine and meets DOT EPA regs.

The only ones I have seen for sale is on ebay and from reading the auction description and terms the seller sounds kinda flakey, not to mention they are based in Brooklyn Ny.

Checkout the swing arm for both bikes in the Parts PDF diagram.
