Las Vegas, Nevada -- TomTom displayed its new Rider GPS navigation system for motorcyles at SEMA (slideshow of photos here on Technoride). It's water resistant, and can clamp on to your bike without bouncing off.

It sports the new SiRFStarIII technology so it'll work even when you're in a valley between huge skyscrapers in Manhattan. The Rider can also monitor traffic, with Clear Channel traffic reports, and suggest alternate routes, the trick is that you need to carry a BlueTooth-enabled cellphone with you that the Rider uses to acquire the traffic information (via GPRS).

It's available now and retails for $1199, but you'll have to pay for Clear Channel traffic reports on top of that.
