By that I mean a 25mm cartridge fork kit from Race Tech ($1999; www.racetech.com). The Ninja's Showa Big Piston Fork offers a wide range of adjustments, but upgrading to the Race Tech kit makes those adjustments much more effective and precise. This setup greatly improved front-end feedback, which is the key to cornering confidence, paying dividends on the street and track. After dialing-in our 2012 ZX-10R testbike during our "Class of 2012" superbike comparison ("Shogun Showdown," MC, July), I applied the same changes to my long-termer. That involved shimming the shock to raise the rear end 8mm and sliding the forks down so they're flush with the top triple clamp, raising the front end 4mm.
