Unlike Max, I DO have a trunk, and I ride a ton of miles. Sometimes at high speed.
GPS top speed reading was XXX on the ride from Bellingham, WA to Boulder, CO in June.
Ahem. Speed deleted on a public forum and all that, but it was well over the posted limit.
But a bit below 140. In the North of Wyoming, it is posted 80 everywhere. And nobody is going that slow anyway.
I am at about 150,000 miles on three C14s at this point. All with trunks, even though I do not always have it on the bike. Usually I do. At least once or twice a week, I have a biggish saxophone lashed across the pillion. Several different windshields, using the height adjustment often, sometimes a passenger instead of the horn, etc. Sometimes the bags are crammed with stuff.
NO PROBLEM to run a trunk. Or a passenger. Or a bigger windshield. Or a saxophone.
Advice about "stuff that might possibly go wrong" with no evidence one way or the other is hilarious. My actual experience says that there is no stability problem.
37-38 MPG cumulative on the 2008 with a pipe and a PCV. GIVI 45 Litre case. Pretty wide.
Currently running 44-45 MPG usually running the ECO mode on the 2010 I got June 21.
Stock pipe and tune. 8500 miles so far. I do not run them without the trunk often enough to have a with/without comparison.
Taillight visibility is SERIOUSLY compromised with the trunk on. I have extra lights on all of the C14s. Just got them on the 2010. A pair of 4" long LED bars on each side of the license plate frame. One pair set up as running lights, one as brake lights. Integral trunk lights are worth it. That one taillight is just not enough anyway, and the trunk makes it harder to see.
