The electronics revolution is well under way. No longer can a company grab the most current mechanical technology, throw it on its latest repli-racer and wheelie off into the sunset. These days, designing a high-performance motorcycle is just as much about software as hardware.Yamaha’s newest middleweight, the 2008 YZF-R6, is a showcase of such electronic wizardry. The R6 is the bike that in 2007 introduced YCC-T (Yamaha Chip Controlled Throttle), the industry’s first ride-by-wire throttle; and it now incorporates the same YCC-I (Yamaha Chip Controlled Intake) system, the variable-length velocity stacks that debuted on the YZF-R1 last year. The engine also uses two nozzles per cylinder in its closed-loop fuel-injection system, which includes an O2 sensor on the triple-catalyzed, EXUP-equipped exhaust. All these computer-controlled systems have become necessary for the R6 to overcome the performance lost through meeting ever-tightening emissions regulations.
