They’ve gone away from the postie engine ???
and the return of the 350 4T… 1991 was their second ever model….. for as ong as i cold remember it was 450, 550, 650 before the 70ยบ engines. all 100mm bore with a different stroke.
anyway enough of the past.
350 only 1kg heavier than the 250. 501 only .5kg heavier than the 450. both same 95mm bore….
2T: 250 and 300 share the same stroke… each 2T is either under square or a square engine… being 125 and 250 has a longer stoke than bore and the 300 is 72mm bore/72mm stroke.
shame on you STM.. bringing us a link only. …… making us do all our own work on a Saturday and all!
:whistle: :pinch:
