Hope this helps you with your search. With what I understand the rod is same as
ROD KIT FOR GASGAS EC,XC,DE,MC,SM 250/300 .ALSO FITS 84-01 CR250 ,85-86 ATC250R,86 TRX250R.
that certain bigbore pistons for the oem 250r will fit. now 72mm stock gas gas bore is a pretty big piston making the 250r also like a 300. I have not seen any bigger but there are allot of 250r parts out there. |
