My über-bike agenda does have an Achilles' heel, however, and that's tires. For the past 4,000 miles I've been running the Heidenau K60 Scout dual-sport tires (see Heidenau K60 MC Tested HERE), which offer an acceptable combination of off-road ability and highway civility (at least after 750-odd miles, when the edges wear off the front knobs—they really sing before that). The only problem is outright grip, which is significantly reduced compared to a dedicated street tire. This is a problem because with strong brakes, the dead-confident Telelever front end, and Dynamic ESA suspension, the GS begs to be ridden hard in corners, and I'm tired of tiptoeing around to avoid tucking the front. I'm loath to change tires every time I want to go off road (always swapping between street and track rubber is what soured me on my last sportbike experience), but it looks like I'm back in the same boat here. Time to ask BMW for a second set of wheels, which will at least save time compared to swapping tires.
