Kawi tapped Showa for "the first production use of their revolutionary Big Piston Fork (BPF)." According to Kawi, the larger-diameter piston allows lower damping pressure to get the same net result, allowing better feel and feedback under braking. It's also simpler than a cartridge design, which should allow more DIY fiddling. The main frame was stiffened, the engine rotated a bit to adjust both stress-mount points and the overall center of gravity, and additional stiffness was built into the swingarm mounting points. The swingarm itself is longer, lighter and more rigid than before.
