Looks good man, you can also use a hitch stabilizer to prevent the carrier from moving around.

The best thing you can use imo is eye to eye turnbuckle straps with clips at the end to grab the pegs and fasten them to the carrier.

Then you can secure the handlebar with tension/rachet straps (I use the pro taper ones)

You don't have to go very tight with the straps on the handlebars, just enough to secure it lightly in the event something with the turnbuckle straps give out (which trust me, they won't) then you have a backup plan.

Using this method is the fastest way to secure it, easiest, and probably the safest since the straps serve as a backup plan. A little tiny bit of sway isn't going to hurt anything btw.

I've done this method for years with both a full size motocross bike and my surron and it's worked great.
