The real goodies are hidden inside the engine, while plenty of bolt-on suspension and protective parts round out the build. Inside are Type R cams and a thin head gasket to bump compression. Helping the bike breathe deeply is a BMC race air filter and 8.7-pound Yoshimura R-77 titanium race exhaust system. With an EM Pro engine-management computer controlling everything ignition and fuel, the bike gained 17 horsepower on the Cycle World dyno (176 hp and 78 foot-pounds of torque). Total bill for performance mods: $4605.The chassis received a 17mm-longer shock linkage, Showa kit shock, fork-cap extenders, swingarm-pivot inserts, braided brake lines, Galfer pads, fully adjustable rearsets and Yosh's line of crash protectors. Chassis upgrades tag on another $3900.
