Brake pads still look like new at 22,400 km, although I did have the rear master cylinder fail in Louisville in June while I was on the way to a rally in Minnesota. Kinda hairy to drive 2,700 miles with only one brake, but I made it without incident. It's now fixed.
I haven't kept close track of how many of what type miles I've ridden. Adding up the longer trips, I come up with about 4,000 miles of interstate driving. The rest was in suburbia, on back roads, or touring on the Blue Ridge Parkway/Skyline Drive, with occasional trips into town and short hops on I-20 to avoid going through the middle of Columbia.
My long term gas mileage prior to the Minnesota trip was 63. The 52 mpg average on that trip dropped my overall average down to 59, but it's creeping back up now that most of my riding is running around the immediate area. The best I got was a little under 78 on the 105 mile long Skyline Drive with a 35 speed limit, followed by several tanks at 70 or a little better on the Blue Ridge, speed limit 45. Running wide open on the slab yields only 48-52 mpg. The bigger bikes do better at interstate speeds, but I more than make up for it when we slow down.
