To achieve this, Yamaha's engineers borrowed from Rossi's YZR-M1 MotoGP racer. The "crossplane" or 90-degree crankshaft has a staggered firing order—270, 180, 90 and 180 degrees—to smooth out the inertial energy pulses that make a liter-sized sportbike feel bigger and heavier than middleweight machines. Tech Editor Kevin Cameron notes that this crank is significant because it will improve grip accelerating off corners. A standard 180-degree crank stops and then accelerates all four pistons every 180 degrees, but the 90-degree crank will smooth out torque delivery, as the pistons are firing at different times. And although this trick doesn't actually increase torque, the better feel for traction could give this new R1 the edge in the Open-class wars.A counterbalancer smoothes things out even more, and Yamaha is jumping on the tri-mode bandwagon with D-MODE throttle control, which uses the YCC-I variable intake-tract system to offer the rider three different power-delivery characteristics. In addition to the standard mode, an "A" mode emphasizes low and midrange performance, and a "B" mode softens power delivery for more delicate situations, like rain riding.
