it IS a easy question - but the terminology can cause trouble - so a simple and direct answer to the question i *think* you are asking.
a stock 110 engine - has stock rockers, lifters, pump, pump plate, stock crank - stock cases bored for the large cylinders,
a 110 has 110 heads and 255 cams, and is a stock 96" engine other than that. - 103 engines are stone stock engines with big bore cylinders and big bore pistons - no other se parts in there at all. so to be precise a se 103 engine is exactly the same as 96 with big cylinders and pistons - a se 110 has heads, cams and big cylinders and pistons - nothing at all else.
se cranks are better than stock cranks - well they claim they are better i really don't know. some of the se cranks are forged and machined rather than cast - a 110 engine has a cast crank. but se cranks do NOT come in se engines - except:
the ONLY se engine that has most of the se parts in it is the 120 - it has the billet pump plate and big pump and a forged crank and se lifters and se bearings mva heads, machined rocker boxes, .. all the rest of the "se" engines are 96" engines with bigger bores, the 110's have completely different heads..
this IS oversimplified because there are a few se engines on a few cvo bikes of a few years that have a few cool parts...
