Different front disc style on 749

[900MAN]

Friend picked his 06 749 yesterday but has different front discs to my same year and spec bike.
Mine has a flat surface to the width profile whilst his has a ridge channel?

Yours is clearly a fake. I'll give you a tenner for it and that's cuttin' me own throat...

[900MAN]

That's bloody helpful ;o)

Ps shall I bring the £20 for the clutch spring set?
