I'm 6'4" 35" inseam w/boots riding a 2014 DL1000A. Most of the things mentioned I've added including a Suzuki tall seat. The standard seat pushed the family jewels into the tank, with the tall seat I can almost flat foot stopped. Have the peg lowering set from Adv Tech but don't have them on yet, based on the mentions/reviews here will be first thing. I also added the Givi Aeroflow. I think it's really ugly but it's also really really effective.
The 2012-2014 DL650 Adventure came with aluminum side cases and around 40 lb lower weight and better gas mileage than the DL1000.
DL1000 got a pretty much complete rebuild in 2014 and mobetter electronic suspension in 2018.
In the early 2010's, before I got serious about buying an Adv bike, sitting on Suzuki's at the bike shows, the DL650's were always much more comfortable ergonomically.
Check out Motorstorm.it for anything Givi, great prices and I usually get delivery to Minn. from Italy within a week of ordering, often before the US vendors have started to ship.
