There is no side rack for the FX, the top rack cannot bear that kind of load, and the stock charger is half the size of the S platform stock charger and has no pan.

The best arrangement for an FX is probably a tank pannier style side mount. Probably using bent aluminum around the frame itself and not around the plastics.

Crash bars are available, so wouldn't boxer-style be doable?

I suppose so, yes. Depends on whether there are more attachment points for a mounting plate above and behind the bars. I can look at the Cafe Primo soon to see.

Hi there,
Couple things I want to go over. Yes, mounting SuperChargers on an FX is a potentially tricky ordeal. We want to keep them near the tank area instead of the rear/tail for obvious reasons assuming you're riding in the dirt. Therefore it would seem like a better idea if the tank plastics and stock chargers get removed and sort of A-frame is fashioned to let 2 units mount there assuming they're completely out of the way of handlebars and legs/knees.

The next is that while 2 units is over the 1C limit, it's just barely. Because there is a limiter on the packs it's not like our units will go beyond 1C and void your warranty.*

*unless you want us to do that for you. 3C charging awaits the brave...

Anyway if you have 2 units at 6.6kW and you have a 6.4 pack you'll be missing only 0.2kW and you'll be comfortably riding that 1C threshold. My brother currently has over 20,000 miles on his 2014FX and will not, under any circumstances, go back to anything less than 2 SuperChargers.

These are the likely areas for mounting. There aren’t many fastener anchors, but a bent aluminum sheet that straddled over the battery compartment would probably anchor fine with a few bolts here and there against the frame.

The drop bars are helpful but insufficient without a frame side fastening.

Hm?  I'd assume if they can take the full weight of the bike and the rider, they should be able to take the weight of a 3.3kw charger.

They're not meant to take that kind of dynamic loading.

Let's say you go over a bump with chargers only resting on the bars. The chargers will tend to push the bars down and as a lever against the center.

It would be better to attach them to a sheet of metal against the frame so that the chargers pull on that in addition to pushing on the bars.

This is just my thinking right now. I just think the best place for the chargers is by bending aluminum plate around the top of the battery compartment and fastening chargers to that. The bars help; I just wouldn't personally feel good only using bars.

An aluminum *plate*, trimmed of corners, mounted to the frame, would be good, in addition to the drop bars, yes.  Would also help with heat dissipation.  That would be really solid, and help with any dynamic loading concerns.
