The STIHL 045 AVE Super is the big-bore version of the STIHL 045 AV.
All the 045 SUPERs have electronic ignitions, unlike the earlier 045 versions, the first of which was non-electronic.

These fantastic images of the 045 AV Super come from ArboristSite, submitted by user ‘blsnelling.’
I believe this following image from chainsawcollectors.se is one… it has the additional SUPER tag between the choke and on-off switches.
What’s the difference between the SUPER and SUPER II?
Nothing significant. It’s thought the SUPER IIs are simply later versions with minor performance or feature tweaks. The only differences on Acre’s Internet listings are that the SUPER has a chain brake and weighs 9.1 kgs (20 lbs) and the SUPER II has no chain brake and weighs 7.9 kgs (17.4 lbs).
It’s hard to say whether this is accurate or not, so for the time, it’s a bit of a mystery!
