These cylinder heads were actually made for Lambro 175cc 3 wheelers and have a 62mm internal combustion chamber BUT have 200 STUD SPACING ( as 175cc Lambro’s had 200cc cylinder stud spacing as standard ). Apart from being ideal for tuning purposes, the real beauty of these heads is that any capable engineering / scooter shop can open out the inner diameter to the required size ( i.e. 66mm for 200’s, 67mm for 205’s, 70mm for 225’s / TS1’s etc. etc. ) for a minimal fee.
