There has been some discussion on Facebook about swing arm flex on the RFN (also applies to the Beta Explorer). Quotes from Facebook are shown below.

Gene Carbonell:
Mrr Kushmann, somehow you got lucky, this bike we just received three weeks ago, before the 43 amp hour bikes. I took this photo before it got sold.

Gene Carbonell:
Mrr Kushmann, this is what the 43 amp power bikes look like now.

Mrr Kushmann:
Gene Carbonell wow it’s like they forgot to put it on. That’s so weird. I wonder why some of the new ones come with and some without? It totally looks as something is missing.

Gene Carbonell:
Mrr Kushmann, none of the bikes we received from August to November had that cross brace. It’s only been these new 43 amp hour bikes that have that brace.
The swinging arm is even notched to accommodate the plate. That means at a bare minimum, there are three completely different pieces between old model and new model.

and later...

Mrr Kushmann:
Once you get use to the flex I think you’ll actually like it. It makes the bike hook up a little different. I actually love the drifting feeling it gives you. I have come to love the Flex. I noticed more flex in the RFN than in my Surron and my mx4. But as I said I got to liking it.

Gene Carbonell:
Mrr Kushmann, agreed. The flex is by design. Maybe the larger fellows need some more reinforcement?

And we have what I can only describe is the ultimate solution for swingarm flex. Celeste Moody Halko (aka David) has posted on Facebook a description and pictures of a highly modified RFN. Besides the KTM forks and Arma EXT rear shock, the piece de resistance is the swingarm.

'Welded and boxed in rear swing arm using 6061 aluminum (keeps flex to a minimum and prevents the "rear steer" that you will get with the stock swingarm riding hard and fast over varied terrain).'

The RFN is for sale, and here are a few pictures:
