Went on a 4900 mile trip from Peoria IL to the west and back. In Afton WY, a friend on a Multistrada took a rock to several location on his radiator and developed a couple leaks. Believe it or not, StopLeak fixed it and he finished the trip and rode all the way home to Greenville SC. Their radiators are much more exposed than a C14 but it's still a big deal if you puncture a radiator, we thought it might end his trip.
A guard will be ordered post haste! I want one on before we go to Maine next month.
I lost an HID headlight on the road and was concerned about my Pirelli Angel GTs that were new when we started but they held up well and probably have a max of 1000 miles left. My other friend with a Multistrada (yes, there were 2, 2 C14s and a BMW RT1200 also) replaced a chain on the road, then that chain died and he got another one, then got a flat he could repair and had to put the bike in a rented truck the last 500 miles. And no, that wasn't cheap.
