In the UK I very much doubt I would ride an R3 - I find mine way too clumsy, anywhere but motorways or major A roads, when I am over.
On the lanes where I learned to ride and where I love riding still, something light with flat bars rules - The R3 torque is wasted on rural roads strewn with gravel, mud and cow-poo. There are a few where the
@idk curry burner would be overpowered. It is easy then to see why the Adventure category draws riders. The Adventure class grew due to a demand from Alpine riders too. Personally I find the seat height offputting.
I'd be riding something like a CCM Spitfire in the lanes I think.
