Interesting airflow discussion
Linda and I took an 80 mile or so ride yesterday on our KLR650 as I wanted to run last year’s gas out of it. It was a cool day in the mid-50s so I wasn’t sure how warm she would stay on what is basically a minimally faired bike with a pretty small windshield.
When we got home she said she was plenty warm as she gets less wind on the KLR than on the LT. I was pretty surprised by that, but she insists the LT is worse for her than the KLR, and I have the largest Vstream windshield on it now. Apparently, the fact that the KLR has a flat seat (well, it may rise slightly towards the rear) and she sits both at the same level as me and closer to both me and the windshield, causes her to have a better still air pocket than on the LT. I suspect it has to be that she sits higher than me on the LT due to the stepped seat, though much less stepped than the GTL, and she sits farther back which apparently lets the wind off the windshield come in between us. I guess this should not be surprising as I have always felt air pressure on my back when both the stock and Vstream shield when in the fully upright position. I think the air is coming over my head and shoulders and starting a vortex right behind my back. I would love to sit on my LT in a wind tunnel and see the airflow both solo and two-up.
Anyway, I realize this doesn’t add a lot of value as an LT discussion, but it was certainly a surprising finding to me anyway. I really need to try out an RT now as I think the RT puts the passenger a little closer to the rider than does the LT, but I am not sure. I thought this might make us a little more cramped, but it may actually be better from an airflow and turbulence perspective.
