Roughly 25 feet after mashing the KTM's six-speed into low gear, the 950 becomes the most confidence-inspiring off-roader in this quartet. No surprise there. It's lighter, stronger and rides on real dirt-spec WP suspension. Arriving at the top of a mountain first, the KTM pilot's biggest challenge is finding something to do until the others show up. Still, discretion is valor on these things. It's best to take your time. Think observed trials, not motocross. Precision, not feckless bravado. At that rate, the BMW is a corner or three behind its Teutonic colleague. Despite its extra mass and a Telelever front end that isn't as compliant or communicative as the KTM's inverted WP fork, the 84-horse Boxer does a credible Panzer impersonation, laying down usable power from 2000 rpm and chugging through essentially anything the Michelins can get hold of. Switching off the ABS helps, but the GS's front brake is touchy; strictly a one-finger proposition in the dirt. The KTM's brakes are less powerful but more effective and much less scary. The 91-horsepower Suzuki suffers from cantankerous low-rpm throttle response, softish suspension and slippery-when-wet rubber-covered pegs. Some distance behind, the Tiger just suffers. With even softer suspension, slipperier-when-wet rubber-covered pegs and a peakier power delivery, it's an unhappy cat on the rough stuff.
