Here's a great article about a tricked out a Hyper put together by Brian Catterson over at Motorcyclist mag. He put on a set of D616 tires which, in my opinion, look REALLY COOL and, apparently, work great as well!
AVON Pro-Xtreme - Rain - I am about to give these a try. Have read only good things about them. Sticky on asphalt, grippy on dirt, and hell they actually come in the right size for our HM's. Anybody else have any experience?
