Yamaha R6



This is the bike that revolutionized the 600cc supersport bike segment. Twice. When it was launched in 1998, it was the first ever bike in its segment to have a power output higher than a 100 bhp. It sold like hotcakes and left the competition eat its dust. Yamaha had somehow brought back the feel of the screaming two-strokers of yore. It even had the characteristic thirst for fuel like a 2-stroke rocket.




Then, in 2006, when the original R6 had been left behind by the ever aggressive competition, Yamaha gave it a new lease of life. Overnight, the R6 transformed into a track demon, slashing lap times and winning the hearts of enthusiasts and journos alike. Like its bigger brother, the Yamaha R1, it has inline four cylinder engine, tuned for a massive thirst for revs and peaky power delivery.



It competes with other 600 cc super sport machines such as the Triumph Daytona 675, the Ducati 848, Kawasaki ZX-6R, Suzuki GSX-R600/750, and the Honda CBR600RR.




History

The Yamaha YZF-R6 was introduced in 1999 as the super sport version of Yamaha's Yamaha YZF-R1 super bike, and as a companion to the more street-oriented Yamaha YZF600R sport bike which continued to be sold alongside the R6. The motorcycle featured Yamaha's completely new engine design capable of producing over 108 hp (81 kW) while stationary. The R6 was the world's first 600cc production four-stroke motorcycle producing over 100 hp (75 kW) in stock form.



The YZF-R6 has been revised several times since its introduction. Starting with the 2003 model, the R6 became fuel-injected. The 2006 model year was a significant upgrade with a new engine management system featuring the YCC-T ride by wire throttle and a multi-plate slipper clutch. The 2008 model incorporated the YCC-I variable-length intake system to optimize power at high engine rpm and an improved Deltabox frame design.

Controversy


2006 R6
In 2006, Yamaha advertised that the R6 had a redline of 17,500 rpm. This is 2,000 rpm higher than the previous R6 model and was the highest tachometer redline of any 2006 production four-stroke motorcycle engine. It was widely reported that the 2006 YZF-R6's motor did not actually have this engine rpm redline level and was closer to around 16,200 rpm, but because of a deliberate tachometer error of about 8%, it read 17,500 rpm on the tachometer. In February 2006, Yamaha admitted the bike's true engine redline was more than 1,000 rpm lower than what was indicated on the tachometer and had been advertised, and offered to buy back any R6 if the customer was unhappy.
