Here's my bike as it was set up the day of the challenge.
I had a slightly compromised Givi rack at the time (insurance replaced this rack with a new one on my 2013DS when a car knocked it over pretty hard) and I'd quickly mounted it on the DSR the night before with my Bags-Connection Aero cases, which I like quite a bit and are reasonably aerodynamic. I bought those originally for my V-Strom after noticing the mileage penalty I was paying for the stock TraX case kit Suzuki was selling (TraX reduced 58mpg to 48mpg in headwinds at 65mph, Aero brought it back up to 55mpg).
I've since installed a wider sturdy Happy Trails rack to support a tail or something, but it'd be nice if there were really slim aerodynamic side cases to bolt on, or even slimmer cases to bolt to the inside of the rack and have the outside frame a tail.
Come to think of it, it was seeing Vic's bike in detail that day that inspired me to start with the wheel covers.
