I have an 08 C14 and one of my buddies had an ST1300. Both great touring bikes, as long as you know what you're comfortable with. Even though they're outdated, they feel refined. HEAVY though. Yikes. The C14 is more aggressive, in seating position and attitude. To me, the ST feels like it's somewhere between the C14 and a Goldwing. Someone on this forum described the C14 as "riding a refrigerator." I love that.
