Hey Kevin, how's the summer treating you and Kathy? We just spent three weeks up in central Michigan seeing friends and family while looking for property.
To answer your question about the H63 and the H68, H is the speed rating for the tire, 130 mph for H. 63 and 68 are load ratings, 600# and 694# respectively. On her bike either would be fine.
Linda's been saying that riding hurts her hip and she's getting a bit reluctant to ride on the Harley with me as much. We took both the '09 SERG and the Honda Helix 250cc scooter to MI on this trip. We rode the Harley once and I put almost 300 miles on the Honda. She says the Honda is a softer ride and easier to get on/off too. Actually that damn Honda will haul our asses around at 65 mph without much trouble and it's a hoot to ride.
So the '09 SERG Orange/Black with only 23,600 miles may be up for sale in the not to distant future...

Although I will still have a "Harley", albeit in a car project coming up. It's a CVO too, so I can keep my "membership" here!

Take care and tell Kathy Linda and I said HEY!
