I ride it today and damn what i like this bike, it fits me like a glove. I got a oil filter and new oil for it so i will open it up again and take better pics and see how the oil looks. im a bit worried so i didn't overtight the cct. But the bike sounded good and was going good. I was about to sell this bike when i got my kawasaki ninja h2 but now i think i will see my r1 and keep this and the h2 :wink2:
I recently changed mine (front was gouged on the old one) and compared the old and new.
The part is made of a piece of metal over-molded with some type of rubber or maybe Delrin which is nice slippery plastic.
What you see are the knit lines of the over-molded material as it flowed around the back of the injection mold.
