F800 vs 990
I tested these two back to back a couple of weekends ago, on road and off road. My last bike was an XRV Africa Twin (Brits for you) so both bikes were going to be more powerful and better handling. The KTM feels like an overweight 'crosser offroad and a supermoto on road. The BMW feels very firm on road, like a normal roadbike with extra ground clearance, and still like a roadbike offroad. Even on road tyres, the KTM felt ready for dirt, the BMW just didn't. Both have razor sharp throttle response but the BMW was worse, especially the engine braking. They were both comfortable and the finish better on the BMW.
I liked both but I'm now in the market for a KTM 990S (no ABS please)
