[macscr125]

does anyone know if the 2002 cr125 exhaust flange and metal gasket will fit on the 2001 cr125? also, will it fit into my bill's pipe? i heard this increases bottome end a little bit. let me know. thanks

the 2002 flange is narrower and the cylinder will need to be welded up and reground to match the flange-eric gorr will do this kind of service for a good price.It will give more bottom but nothing like a KTM,RM,YZ has.
