Does anyone have a 08 upwards ZX6R or ZX10R that would know, or could measure the front axle sleeve that the axle screws into as per the photo? (Shiny silver bit on the left)

Im looking for a 30mm sleeve that a 25mm axle screws into, ideally about 42+mm long, the longer the better as I can cut it down.

Cheers & thanks!
