Ø40mm tapered cylinder head stud for 50cc BIDALOT Racing Replica kits on minarelli am6 and DERBI euro 3 & 4

Here is the spare Ø40mm cylinder head stud for the 50cc BIDALOT minarelli am6 and DERBI euro 3 and 4 kits (does not fit on DERBI euro 1 & 2). This model is the tapered one, it normally mounts on the 50cc replica version but it will also be able to mount on the racing pro version if desired. The finish, like all BIDALOT parts, is excellent, it is delivered bare without joints.
