Looking at asking prices for the 23 bike, it seems they are ?4-6k more than I paid for my new 22 bike 6 months ago. Aside from the wings and electronic updates, I can't see where the extra money was spent. As it happens I don't like the look of the wings anyway, and I'm wondering if in time BMW will offer a traction control update on earlier Gen4's. I know Ducati did that on my old 1299S.
