Jeeper, I almost forgot this one. Call Rocky Mountain ATV/MC at 1-800-336-5437 and get their Spring/Summer catalog. Makes for good wish-listing when you're not near your computer. They have a website too. Its.
www.rockymountainmc.com
And also,
www.whitebros.com. A friend of mine gave me his White Brothers catalog, but he said it costs like $15, this one's not free. Its got gear and parts, pretty extensive. I'm sure you'll get some other good advice from the people here in the forums.
I just got started too, but I had some really generous friends who GAVE me everything I needed apparel-wise til I started figuring out what I needed, including a new helmet, pants, gloves, goggles, knee guards, and lots and lots of patience and support!! Gosh I have great friends!! Think I'll go ride with them this weekend!!!!!
