Not much is available that is made specific to your bike. The bike did come with a skid plate and there is a rear rack that I think was either an option or was an aftermarket part. If you do a google image search you'll see a couple of bikes with the same rear rack. I have one of these and it looks better in picks than in real life. It also weighs a ton.
I'm leaning towards fabing up something custom and selling the one I have but I want to hang onto it for a couple of months untill I get a chance to weld something up. If you are interested I'll let you know when I sell it.
As for side bags or crash bars it will have to be custom.
