Having grown up in that area, I understand your reasoning for the K1600 as a commuter on I-95 as long as you dont have too much "in-town" riding between the house and the interstate, and between the interstate and work. I-95 between Stafford and DC is a bitch at the best of times, HOV makes it bearable at least.For me, right now, the K1600 is best for what I need a highway bike to do.
if I had your commute, I suspect I'd do the same as you. The Multi is capable but a little noisy and "nervous" on the highway (it's light weight, high profile, and wide bars that make it so responsive in the twisties work against it when droning on the slab).
Maybe a second, weekend playbike (Street Triple, Hypermotard) is in your future:think:
So you didnt love the triple? I did ride one recently and that motor is insane. Not sure I would to many miles on it but for an hour or two of canyon carving seems like it would be a blast. ( But them again so is the Multi). I have come to believe that motorcycles are like women. You might have your hands on a total babe but you always want something new..Dave,
I did not mind the noise and and found my Multi very controlled at speed on the highway. Even with the risers i could take one hand off the bars and just do lean turns.
My previous bike was a Truimph Street Triple R, and found it too low and forward. The BMW doesn't have the same punch as the Duc. It does have a very smooth ride though. For my commuting that is important.
I love my S3 (all the things you said above are true) but honestly I'd take the MTS1200 all day over it for both commuting and the canyons. It is twice the cost though!^ not many out there that don't like the Speed Triple. Smooth motor, ,good handling, great value are words often used to describe them.
