Motorcycle specifications YamahaYZF-R1 1000 Factory SUPERBIKE 2011 The technological armada

the R1 will start the 2010 season proud of its 2009 SBK World Championship title. Unfortunately, it will no longer be piloted by the incredibly talented Ben Spies, who has left to conquer MotoGP. But the Sterilgarda team's 2 new riders are no slouches. The first is none other than Cal Crutchlow, 2009 World Supersport Champion. The second is James Toseland, fresh from Tech3 and 2004 World Superbike champion. Quite a line-up on the Yamaha.

as far as the R1 Factory is concerned, there are few cosmetic changes, apart from a new fairing. Most of the fairing is in honor of sponsor Sterilgarda. On the technical side, the hypersport gains 8 hp and loses 3 kilos, while retaining its electric starter. The fuel tank is now made entirely of carbon and has a slightly larger capacity. The lower fairing has been redesigned to reduce drag and improve heat dissipation. Cooling capacity is also enhanced by the different shape of the radiator. Finally, the new exhaust system provides better mid-range filling. Before becoming the superb tool that Tom Sykes and Ben Spies had in their hands, the R1 underwent a number of modifications. From the sports bike available from your dealer to the Factory version, the difference is considerable. And even though the regulations stipulate that Superbike machines must come from the series, the 2009 missiles have never come so close to being protos. Let's take a look:

let's start with what's most obvious - the R1's fairing is entirelycarbon, as are the mudguards, air intake tubes, casing protectors, self-supporting seat and airbox. The airbox has not only been modified in terms of material, but also in terms of volume. Larger, it allows the 4-cylinder to breathe more easily. The fuel tank above the airbox is really just a cover; the real one has been moved under the seat to optimize weight distribution. As permitted by regulations, it holds more fuel than the original model, over 23 liters (the FIM allows up to 24 liters). Yamaha Racing took advantage of the space freed up to fit the extra electronics on this Factory. You can't imagine the host of instructions that flow from the multitude of sensors and the ECU control unit. Fork depression, rear shock absorber work, tire temperature, exhaust gas richness, wheel rotation for traction control, intake air quantity, clutch position, etc....
On the left-hand commodo, the classic turn signal and headlight call controls have been replaced by a panoply of control buttons. These are used to engage launch control, the pit lane speed limiter, and to modify traction control and fuel injection mapping to suit the circuit, the weather, the tires and their wear. The system goes so far that parameters can be modified by the rider, or by a GPS signal depending on the machine's position on the circuit. The era of electronics has well and truly taken hold of the racetrack.

is adding endless horsepower out of fashion? Not really. But engine management and efficiency are assets that no team can afford to ignore. It's no longer just up to the drivers to harness the fire of their engines, even if they still need a very big pair of .... to set the fastest lap times. The blast from the Akrapovic titanium/carbon exhausts leaves no doubt as to the vitality of the Yam block From 182 in the standard version, the R1 boasts over 220 horsepower at 14,000 rpm. Maximum revs are raised to 15,000 rpm. Magnetti Marelli fuel injection and extensive work on camshafts, combustion chambers and intake ducts enable the YZF Factory to announce this very big powerplant, which is nonetheless inferior to the surprising RSV4 or the discreet (this year) CBR 1000. The extra 30 or so (official) horsepower required the addition of a high-capacity radiator, the price of which alone would buy you a used 600.

the chassis retains only the original frame, the only element that cannot be modified. The swingarm is a 15% stiffer model. The all-Ohlins damping comes from the best school of all: MotoGP. Both forks and shock absorbers come from Doctor Rossi's 2008 M1. The Brembo monoblocs are of course radial-mounted, anchored to solid mounts. Staübli-type quick-release couplings allow them to be replaced in seconds. Finally, 16?" magnesium wheels (which can be lifted with a fingertip) transform the R1 into a Superbike champion weighing less than 160 kg. The hunt for weight in SBK is merciless; but despite this, and thanks to its super-light weight, the Yam allows itself to be the only machine on the grid to be equipped with... a starter, just like any other bike on the planet.
