Hey, some time ago I purchased one of the aftermarket kits from China off Ebay. I was amazed with the fit and quality to be fair, it went straight on and the only thing I had to do was add some self adhesive heat shielding near the exhaust. I wouldn't hesitate to buy one again. They do OEM colours etc and I think for the money it is spot on. I didn't go OEM colours and instead went with the current year WSBK paint scheme on my K1 which turned out..... well a lot of people hated it but I loved it
