The term "ATV Gear" to me usually means, stuff like gloves, goggles, ect.
As far as what your after, well not to be rude but your a little late to the party. This is a 2 year only quad over a decade old. A lot of the aftermarket parts are hard to find now. Even the Honda Racing skids, nerfs & bumpers have all but disappeared.
Keep a eye on eBay, I've seen some good deals on nerfs. Maybe you'll get lucky and find a bumper. I think Ricochet off road still makes skids?
Quick is right. I bought Ricochet skids brand new from Ricochet in 2018. Same for nerf bars from Alba racing. OMF still makes wheels. Everything else is hard to find. I did buy a dg rear rack on amazon. What you find on ebay for the 700xx is about all that's still out there.
