I`m a biker and your site is already better than 95% of motorcycle gear sites I have seen. Nice work.
I did notice some field layout issues on the my account page on both FF2 and IE7. It looks like some of the fields are too long, which makes them wrap to the next line. It looks a little confusing.
I would widen the site as CraidgL suggested.
Also, I would make make the categories much more visually noticeable. It gets lost in the other links. It should certainly be more important (higher on the page) then Reviews. I actually think the green my Account, etc. bar should be removed, and the links moved elsewhere. This is tertiary information, and selling should be the top focus. Maybe put categories there.
Hover and selected states would be nice for the main navigation as well.
Keep up the good work, and good luck with sales.
