Hello chaps, I was just going to order an oil filter from wemoto when they present me with a choice of two! One is long.
I am at work at the moment so can't rip it out, does anyone know owt about it?
edit: it's ok I found it all out with a simple search "rsv mille long oil filter"

I think the description "sits flush" is maybe a little misleading.
This picture should help - the standard filter housing is on the bike and the one for the longer filter is being held in front:

The longer filter was an "upgrade" Aprilia "recommended".
Perceived wisdom is that it doesn't really give any appreciable benefit but was a convenient change when Aprilia changed suppliers.
Both filters are still available so just choose the right one for the cover you have.
