So what are the downsides to it? They are mostly obvious. First, there's the need to remember that not all bikes can be converted to reverse shift, unless you only ride your own bike and don't ride dirt bikes (which due to their lack of a shift linkage, among other reasons, don't run reverse shift patterns). If you're fortunate enough to ride a lot of bikes, like magazine road testers and track-school instructors, you need to always be careful to remember which way the bike under you shifts or risk making The Big Mistake. Take it from me, this is not something you want to learn from firsthand experience. I've made The Big Mistake not once, but twice. (I can be a slow, painful learner at times.) Both crashes were, of course, highsides, and both occurred on the track (thankfully with an ambulance nearby at the ready). Both times I allowed myself to be distracted (once by a new onboard radio system and another time by a fellow SR staffer who was running counter-course direction doing photos while I was performing the test's official timed laps-I know; don't ask what we were thinking), let my brain slip into racetrack mode and executed an unintentional clutchless downshift while exiting a corner hard on the throttle. The results were both predictable and spectacular. The first situation ended with me in the ER for X-rays and a STAR School Suzuki TLR1000 being totaled; the second resulted in the launching of myself and an older Suzuki GSX-R1100 off the crest of Willow Springs' turn 6 hill. Amazingly, we both got back up, brushed ourselves off and carried on-the damaged-on-one-side Suzuki even making the cover minus one mirror.
