Motorcycle specifications YamahaYZF-R6 600 2014 Give it some gas!

still no changes for the R6, which is entering its 6th season in Supersport (the 2010 evo marked too few changes to be significant). Aged in the calendar, it has lost none of its charisma. A pistard to the end of its connecting rods, the R6's magic is as strong as ever, and even more so after the 2010 update. Don't look at the design, you won't see anything - it's all in the mechanics. The muffler is ten centimetres longer than before, bringing it up to speed in terms of emission control and improving the flow of exhaust gases. Yam has also worked hard on air intake and electronic engine management. A larger airbox ate 1/3 liter from the fuel tank. But these modifications give 10% more torque and better mid-range availability. On the scales, the R6 gains 4 kilos.

Being the most extreme 600 sports bike doesn't exempt you from a thankless but indispensable law: evolution. And even when your name is R6, you can't escape it. But miss pistarde isn't worried. With Yamaha engineers at the helm, and an incredibly formidable potential on the track, the 2010 - 2014 version of this furious 600, like the 2008, will continue to delight many.

let's look back at its genesis, which basically dates back to 2008. Technology enthusiasts will appreciate. After adopting the YCC-T ( drive by wire ) throttle control system, in 2008 the R6 borrowed the YCC-I (Yamaha Chip-Controlled Intake) variable intake system from its R1 sibling. A unit in the airbox that allows you to modify the length of the intake cones.
The intake manifold is divided into 2 sections, the upper one being movable, activated by an electronically-controlled servo-motor. At low revs, to improve torque, the horns are uncoupled and air flows through the lower section, resulting in short intake manifolds. This improves engine response to acceleration.
Higher up the rev range, at a certain rpm, the upper section lowers and covers the base horns. As a result, the intake manifolds are longer, providing more gniak at higher revs. A modification to the airbox was essential, and its orifice was also improved to reduce air resistance.
To better manage this cocktail of electronics and intake, Yamaha took the opportunity to review the YCC-T and injection settings. All the more so as the engine-makers have added patator to the boiler.

13.1 to 1, sound familiar? That's the compression ratio in the R6's cylinders. Quite simply, the highest compression ratio ever adopted on a production Yam. With 12.8 to 1 on the old model, it was already compressing quite well. But now, it's really strong. This was made possible by the new high-compression pistons. Distinctive feature: their slightly convex caps allow a "sloping roof" combustion chamber.
The internal modifications don't stop there: the cylinder head recesses have been hollowed out to accommodate the four ultra-light titanium valves. To cope with the increased loads created by these new pistons, the connecting rod bearings have been enlarged, and the main bearing lubrication port has been redesigned. In addition, the intake and exhaust valve springs are now made from a more durable alloy, guaranteeing consistent, efficient valve work under extreme driving conditions on the racetrack. The timing chain tensioner benefits from a palladium carbide treatment designed to harden its surface and guarantee consistent chain running quality.

On the exhaust side, the intermediate silencer at the outlet of the 2nd and 3rd cylinder pipes has been enlarged by 30%, again with a view to improving low-end torque.

that was the technical side. In terms of pure power, the R6 lost a few horsepower in 2010 (who knows why?) and has since developed some 124 hp. An already muscular hara, hysterical at the revs, but losing some of its nobility in the face of the ex-motorcycle's trailer and its 135 hp obtained at 14,500 rpm (129 without forced air intake). The same power output as a 750 not so long ago. Except that today, around this power, there's an EXUP, titanium valves, anti-dribble, a Drive by wire YCC-I throttle, a variable YCC-T intake, and a chassis that has also evolved.

thanks to its mastery of die-casting technology, Yamaha redefinedfinished the frame's rigidity distribution by modifying the wall thickness of the two side beams, particularly at the rider's knees. At the same time, the wall of the steering column has been thickened to increase rigidity, while the crossmember that connected the left and right sides of the Deltabox frame has disappeared on the 2008 model, as it did on the 2007 R1.
These changes are almost impossible to see with the naked eye, but are intended to improve handling and increase the R6's cornering precision. Nothing is left to chance in this respect: the new fork stanchions also benefit from differently distributed rigidity, a new lower triple clamp and a longer triple clamp offset. Braking on this formidable front end remains the excellent double 310 mm disc with 4-piston radial calipers; the only change is in disc thickness, which has been increased from 4.5 to 5 mm.

you know magnesium as the material used for crankcases and certain frame components. On the R6, it's also used for the rear cadre. That's 450 grams more weight than before. Underneath, aluminum is not extruded but forged in certain sections of the swingarm. A few centimetres away, the rear suspension has been lightened via a new compression adjuster bracket, as on the 2007-2008 R1. And yet, the R6 has put on weight. 5 kgs in 2 years, for a 2008 dry weight of 166 kgs. - and another 4 kg in the hips for 2010. For some time now, the mad hunt for weight no longer seems to be a priority for manufacturers (except Honda and Ducati).

aesthetics before and after 2010 are subtle, yet the R6 has become even more dynamic (just a little). But you'll have to pay close attention to see that the upper edges of the sides have been redesigned, the mounting point for the mirrors has been tweaked, the new bubble is topped by an even sharper beak, and the top of the fuel tank has been redesigned. Flickers, but the design is still incredibly aggressive and resolutely irresistible: as if adrenalin had guided the designer's pencil.

the YZF-R6's overwhelming efficiency on the track will keep it at the forefront for a long time to come. A little cosmetic retouching, even more electronics and technological aids, more watts, a further optimized chassis... Even with its age, miss R6 continues to express its exceptional efficiency on many circuits and competitions.
