Agree with both Andrew and Alan. Add a few lines of text such as "Welcome to Motorcyle Center. We stock America's finest motorcycle gear, motorcyle parts, biker jackets, motocross helmets and more. We're experienced motorcyle enthusiasts with over xyz years in the industry..." etc etc. Just a basic introduction to your site, what you're about and why people should shop there. The why shop with us banner is just an image, so perhaps incorporate some of that in to your SEO text. "One stop motorcycle shop - largest selection of motorcyle gear, no risk shopping on your favorite motorcycle parts" etc etc.
Also, you're page title is way too long. Try to rank for 2-3 key terms on your homepage first, then go after your secondary terms next.
Your top level categories should have better URLs. "Shop-for-men" doesn't describe anything about "Mens Motorcycle Apparel"
Hope this helps,
