Yamaha YZF-R1 (Catch this eye)

YZF-R1 - genius engineering

The YZF-R1 has been astonishing supersport riders since 1998 and is now well established as the legendary performer of the supersport world. The R1 is for riders who really know where they're at, whether they're on road or track, riders who know that supersport performance means more than just an extreme spec sheet.


The Art of Engineering concept we use to keep ahead of the opposition is about much more than mere numbers, because Yamaha engineers understand that riding well is about feel, feedback and confidence, so we create machines that can get the best out of you on every ride, always challenging you to go to the next level.

Our engineers and designers work ceaselessly to improve the R1, refining its DNA, using MotoGP input and utilising new technologies that allow you to fully exploit its astonishing performance.

The awesome 2007 R1 is the embodiment of that philosophy, utilising state-of-the-art electronics - YCC-T (Yamaha Chip Controlled - Throttle) and YCC-I (Yamaha Chip Controlled - Intake) air funnels - to increase performance and enhance man-machine interaction with a never-before-possible quality of feedback and performance.

Combine these cutting-edge technologies with a new 16-valve engine, a brand-new Deltabox frame and stunning new bodywork and you'll understand why our engineers believe that 2007 is a landmark year in one-litre supersport performance.

Engine

The 2007 R1 uses a new 16-valve engine, utilising know-how from Valentino Rossi's mighty M1 MotoGP bike for more performance throughout the rev range. The engine is Yamaha's jewel in the crown, with titanium intake valves and high-precision fracture-splitting con rods. The result is our best-ever engine performance, 180 horsepower at 12,500 rpm, and that's before the forced air intake system kicks in.

But the fact that the new R1 has more horsepower right across the rev range is only half the story, even more important is how that power feels. That's why this R1 uses YCC-I (Yamaha Chip Controlled - Intake) and YCC-T (Yamaha Chip Controlled - Throttle). YCC-I, the biking world's first electronics-controlled motor-driven variable intake funnel system, ensures ideal power and torque at all rpm by adjusting funnel length to perfectly suit throttle opening and rpm. YCC-T outperforms conventional carburettor/injection systems by allowing an excellent torque curve and, because it always delivers the optimum fuel/air mix, you get perfect acceleration whatever revs and throttle opening you're at.

Chassis

Riding fast, riding well is all about man-machine interaction, so the 2007 YZF-R1, like every R1 before it, has been carefully honed for breathtaking performance on racetrack and twisty roads.

The latest and greatest R1 features an all-new Deltabox frame and upside-down truss-style swingarm which respond exactly to rider input on corner entry and improve rear-wheel force for extra corner-exit traction. And the new R1's superbly damped forks and rear shock feature two-way compression damping for wonderfully accurate high-speed control. The R1 also has a slipper clutch for smoother corner entries and awesome six-pot, radial-mount front brakes too. R1 - it's all about man-machine interaction.
