Pointy speedo drive,
 

Help, just removed front wheel for new tyre and found that the knuckle dragger who last fitted the front wheel didn't bother engaging/lining up the drive before tightening spindel, broken bits must have jammed up inside coz speedo was still working, can pay Paypal, cheque, postal order, whatever, thanks, Fraser

Bike is naked 2003 Pointy.

UPDATE, OK, I got one !! I just used the sticky links and bought a new rotor from Robinsons Foundry, £ 24 delivered, well pleased,
