2014 YZF-R1

The YZF-R1 benefits from MotoGP® technology – a seven-level Traction Control system. The system has been developed so the rider does not feel any unnatural or harsh intervention from the system. In addition, traction control can aid in reducing tire wear due to less wheel spin. Coupled with the three level D-Mode electronic throttle response control, riders have 21 different choices available to tailor the YZF-R1 to their riding preference.

This R1 keeps all the technological superiorities developed for its predecessor: YCC-T® (Yamaha Chip Controlled Throttle) is a MotoGP® inspired fly-by- wire technology used to deliver instant throttle response. YCC-I® 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 repsonse.

In keeping with this machines exceptional cornering ability and crisp handling, the aluminum frame has been designed to offer exceptional rigidity balance.The rear frame is lightweigt Controlled-Fill die-cast magnesium, contributing the optimum mass centralization. Suspension includes YHSJ (Yamaha Hydraluic System Japan) front forks which use one of the tricks developed for our winning MotoGP® bikes: independent damping. The left fork handles compression damping and the right side handles rebound damping. And the rear shock adopts bottom linkage for optimum suspension characteristics.

The sound on the YZF-R1 is unlike any other inline-four cylinder production supersport. The precise and throaty pulse of the exhaust note will have riders enthused every time the thottle is opened.

Compact, lightweight 67mm x 42.5mm, 599cc DOHC 16-valve, liquid-cooled titanium-valved four-cylinder has a compression ratio of 13.1:1, for great response. Domed pistons with valve cutouts produce a compact combustion chamber.
Fuel injection mapping for the YCC-T—Yamaha Chip Controlled Throttle dual-injector system complements the high compression ratio for great throttle response and reduced engine braking.

YCC-I—Yamaha Chip Controlled Intake electronically varies intake tract length for a broader powerband.

YCC-T—Yamaha Chip Controlled Throttle uses a powerful ECU and multiple sensors to provide perfect, smooth engine response and optimal power whenever the throttle is twisted under all conditions.

Twin-injector fuel injection: shower-type injectors above each intake funnel help achieve optimum fuel atomization at high rpm.
Slipper-type back torque-limiting clutch greatly facilitates braking and downshifting from high speed. Close-ratio six-speed transmission delivers seamless power and maximum acceleration.

GP-style titanium muffler contributes to mass centralization and contains EXUP® for a broad powerband, and 02 sensor for spot-on injection and emissions compliance.

Linerless, direct-plated ceramic-composite cylinder bores mean greater heat dissipation for consistent power delivery and reduced friction.

Cool magnesium valve and engine covers are light and stylish.

Direct-ignition coils, dual-electrode spark plugs and high-output magneto deliver extremely accurate, reliable firing.
