Holy Heimlich Maneuver! Rubén Xaus' factory BMW S1000RR took my breath away. In race trim, this fuel-injected inline-Four makes more than 200 horsepower and has none of the road-going niceties—heated handgrips, anti-lock brakes or hard saddlebags—I associate with the Bavarian bike maker. Luckily for me, Xaus doesn't wear a flip-up helmet, either. After my Arai (and Alpinestars leathers, gloves and boots) got held up in customs, I had to borrow his custom-painted full-face Premier for my five-lap stint on his bike at the fantastic Algarvé circuit in Portimão, Portugal.
