Yamaha YZF-R6
The YZF -R6 is a supersport motorcycle category of the Japanese manufacturer Yamaha and is the 600 cc model in the Yamaha R- series. She came in 1999 under the designation RJ031 as successor to the YZF600R Thundercat on the market. The R6 was a visual likeness of a year earlier featured R1.
Care and model history
The engine of the R6 was a complete redesign. Among the new features included, for example, forged, low-friction pistons, coated rods, the five -bearing crankshaft, the spark plug with integrated ignition coils, spark plugs with double electrodes and the downdraft carburetor with 37 mm apertures, flat shifters and throttle position sensor. As with the R1, the gear shafts were above each other, which resulted in a shorter engine. The compacted to 12,4:1 high-performance engine produced 120 hp at 13.000/min. The lightweight 169 kg dry weight R6 left in race trim to up to 56 degree lean angle without touching down.
For model year 2000, the oil scraper and the shift linkage have been modified.
For the 2001 model year, the engine was revised ( changes to pistons, connecting rods, exhaust manifolds, ignition and battery), as well as changes to the steering wheel and equipment and optics made. The dry weight decreased among others thanks to lighter starter battery 167.5 kilograms.
2003 R6 has been completely redesigned. More than 90 % of the engine parts were changed, most important modification is the 38 mm Multipoint fuel injection that replaces the carburetor technology. The new engine continued to make nominally 120 hp 13.000/min in now. What was new, however, that as early as 4000 rpm noticeably more power was available. The suspension side received the R6 is a new aluminum frame made of die -cast and lighter 5-spoke rims. In addition, 4.5 kilograms compared to its predecessor could be saved, and so the new R6 weighed only 189 kg fully fueled.
For the 2005 model year received the R6 -type RJ095 a final revision. Most remarkable change in addition to the newly designed, her tail part was the use of a 41 mm upside - down fork at the fork feet, the calipers were now bolted radially. The operation of the enlarged diameter front brake has been converted to a radial brake pump. The front tire was now the common dimension 120/70-17 ( 120/60-17 instead ), the rear shock linkage has been modified. On the engine side contained the update on 40 mm diameter larger intake manifolds and redesigned air induction.
2006 R6 has been completely redesigned again. The revised engine now made nominally 127 hp ( 133 hp with ram air effect) and a maximum speed of 17.500/min. Real these values are somewhat lower ( about 122 hp at 16.200/min ). Disadvantage of this short-stroke, speed- oriented interpretation, however, is that the new engine generates less power and torque at low and medium engine speed range, which, but is on the track of secondary importance when driving on the highway in a negative sense perceptible. A special feature of the new engine is operating the throttle by an electronic servo motor (drive- by-wire ). The throttles are closed, however, continue with a cable.
Other features of the new model are also the titanium valves, two injectors per cylinder, forged pistons, lighter flywheels, titanium muffler with EXUP exhaust control and a slipper clutch. The chassis is designed front-loaded; 52.5 percent are carried by the front wheel. It is noteworthy that the type RJ095 was sold in the 2005 configuration under the name YZF- R6S to 2009 Yamaha.
The Model 2010 has been revised in some points and optimized: So there is a newly programmed engine management and a modified muffler.
