Unusual rotor drilling pattern
« on: February 14, 2013, 12:28:54 PM »
Check out this 750 for sale, in one pic you can make out that the front rotor is drilled in a repeating "CB" pattern.  Never seen that before, any comments?

If you had a 750F you could match the rear rotor with NICE ASS

that thing a taxi bike?

I was dealing w/ these Belgium car dealers a few years back and asked them if they'd be interested in a yellow vehicle I had. I'll never forget what they said and always think about it when I see something in yellow. "The only cars that should be yellow are taxi's and Ferrari's." Needless to say they didn't take the yellow one from me.

Thought I'd post the pic, so the thread would have it, after the ad goes dark.

It's been common on Hayabusa's since at least 2004, they were lazer cut though
 Guess he saw one somewhere?
 I think doing 'CB' would be easier to keep balanced? (still takes a bit of thought though)
