Key Features:
The YZF-R1 garnered the prestigious award as the 2009 Motorcycle of the Year from Motorcyclist Magazine. The YZF-R1 was chosen for its MotoGP庐- inspired engine and chassis technology, and for its luxurious fit and finish.
Back for 2011, the YZF-R1 is the only production motorcycle with a crossplane crankshaft. Crossplane technology, first pioneered in MotoGP庐 racing with the M1, puts each piston 90掳 from the next, with an uneven firing interval of 270掳- 180掳- 90掳- 180掳. This uneven order does an amazing thing鈥?it actually lets power build more smoothly. That means smooth roll-on delivery out of the corners, with outstanding tractability, followed by very strong high rpm power. It鈥檚 a feeling that鈥檚 simply unmatched, like having two engines in one: the low-rpm torquey feel of a twin with the raw, high-rpm power of an inline four. This breakthrough technology on the YZF-R1 represents a paradigm shift in both technology and performance.
This R1 keeps all the technological superiorities developed for its predecessor: YCC-TTM (Yamaha Chip Controlled Throttle) is MotoGP庐 inspired fly-by-wire technology used to deliver instant throttle response. YCC-I庐 is Yamaha Chip Controlled Intake which is a variable intake system that broadens the spread of power. The fuel injection system provides optimum air/fuel mixtures for maximum power and smooth throttle response.
The R1 features Yamaha D-MODE (or drive mode) with rider-selectable throttle control maps to program YCC-T performance characteristics for riding conditions. The standard map is designed for optimum overall performance. The 鈥淎鈥?mode lets the rider enjoy sportier engine response in the low- to mid-speed range, and the 鈥淏鈥?mode offers response that is somewhat less sharp for riding situations that require especially sensitive throttle operation. Switching maps is as easy as pushing a button on the handlebar switch.
In keeping with this machine鈥檚 exceptional cornering ability and crisp handling, the aluminum frame has been designed to offer exceptional rigidity balance. The rear frame is lightweight Controlled-Fill die-cast magnesium
