The 2015 Yamaha YZF-R1 is ready to beat Kawasaki’s latest 998cc-superbike H2 and Honda’s RC213V-S, which is still a prototype. Unveiled at the 2014 EICMA show in Italy, the 2015 Yamaha YZF-R1 a new powertrain, electronics, chassis as well as a revamped look.

The 2015 Yamaha YZF-R1 is powered by the same crossplane-crank, inline 4-cylinder engine as the predecessors, but with a larger bore and shorter stroke (79mm and 50.9mm vs 78mm and 52.2mm), plus larger intake and exhaust valves. Intake and exhaust ports have been reworked and the valve angle has been updated also. Yamaha hasn’t revealed power figures at the moment, but rumors say it will put out 200hp without ram-air and 82.9 ft-lbs of torque.

According to Yamaha, the 2015 Yamaha YZF-R1 has new fuel injection system and features “two-directional 12-hole main injectors which direct their high pressure spray at the back of the two new large diameter intake valves.”

Overall, the new engine which dubbed as the CP4 engine is 9 pounds lighter than the previous model, and the crank is an inch and a half narrower than the old one.

The 2015 Yamaha YZF-R1 features a six-axis inertial measurement unit (IMU) that utilizes gyros and accelerometers. The IMU is able to establish R1’s lean angle, slide speed and pitching rate, and then communicates with the ECU to provide data and instantly adjusts the R1’s Yamaha’s powerful electronics package including a rear wheel Slide Control System (SCS), Front Lift Control system (LIF), Launch Control System (LQS), Traction Control System (TCS), Quick Shift System (QSS), and Yamaha Ride Control system (YRC) in order to achieve optimum performance with high levels of controllability. ABS system now comes with a Unified Braking System (UBS).

Other features include LED headlights, a TFT display, cast magnesium wheels, a new subframe made of magnesium, KYB fully-adjustable suspension front and rear, lightweight engine internals, large-capacity force-fed airbox, titanium 4-2-1 exhaust system, compact new LED headlights and an optional communication control unit (CCU).
