Welcome to the forum.
Very very nice. 250 2C the best!
We have in our family a 250 2C since 1993, now its done 69K miles.
Metzeler ME22 front 2.75x18 rear 3.25x18It needs a set of tyres. A search here seems to suggest Avon RoadRiders, or Bridgestone BT45.
Please please don't go larger it wont help. 250 2C works best with narrow tyres.
Different size to 350 . Original covers are available from Mdina Italia, however I am sure that is not the original seat, or it has been modified.I was hoping to get a more original seat cover, which is why I was wondering if the 350 is the same size.
Original Grimeca master cylinder has mirror mount its M10x1.25
If you have the unbranded pattern black indicators (as sold by Gutsibits) then use a large o.d. washer (or mating nordlock/serrated style) to ensure its all clamped up or they rattle loose very quickly.
