I don't see that arm squeezing down enough to make the studs work. If you could change them out then you could use heavy spacers to take up the gap - it wouldn't be pretty bit I expect it would serve well enough and I expect you'll need to do something to that effect in any case to maintain cable clearance.

To do it right though you're looking a refabrication IMO. Retain the pivot and have some new box section with the right dimensions welded up with some appropriate relief for the cables.
There's not actually a lot of gap. It's about the width of the torque arm on either side.
I ended up modeling an adapter that I plan to slide over the axle on either side and then into the swingarm.
I plan to make it out of 6061 T6 aluminum, so I left a pocket for the hardened steel torque arms it came with.

Here is an image generated from the mechanical drawing. Hope that is what you were asking for?

It should. The partnership has a 10-year expiration date and I am sure everyone at Zero knows the Polaris/Brammo story and doesn't want to see that repeated. No doubt they will keep their company at arms length from Polaris.

I just saw a post in the Electric Motorcycle Forum that mentioned that a Cycle World article in the past discussed that Polaris sold their Brammo tech to Cummings a couple of years ago. I guess that partnering with Zero to develop EV products is likely less expensive than trying to build up EV tech from scratch. And this partnership should help to insure Zero's financial future. "

" It looks like Zero will be providing the power trains and battery packs for Polaris off-road products, while Polaris provides the chassis design, manufacturing, marketing, retail dealers and distribution network for a new line of battery-powered commercial and recreational vehicles, perhaps including snowmobiles and watercraft.

Our shop runs on <700 watts most of the time even with all of our computers going.

also the standard wall outlet will only do 1100 to 1500 watts. So blenders do not take 2kW to run unless it is an industrial 240vac blender. Even most space heaters are about 1500 watts. Also, there is a difference between Peak spikes and continuous. The average house only has spikes of 6-7kW for very short periods, and only when we are being particularly first world.

Most of our country is also pretty wasteful, check out the data from the Energy Information Administration.
