Yamaha YZF-R 6 model 2006 (RJ11)

The YZF-R 6 is a super sports motorcycle from the Japanese manufacturer Yamaha and is the 600 cm³ model in the Yamaha R series . It was launched in 1999 under the type designation RJ031 as the successor to the YZF600R Thundercat . The R6 was optically a copy of the R 1 presented a year earlier .

Model history and maintenance

The engine of the R6 was a completely new design. The innovations included, for example, forged and low-friction pistons, tempered connecting rods , the crankshaft with five bearings, the spark plug caps with integrated ignition coils, spark plugs with double electrodes and the downdraft carburetors with 37 mm openings, flat slides and throttle valve sensors. As with the R1 , the gear shafts were stacked, which resulted in a shorter engine. The high-performance engine with a compression ratio of 12.4: 1 developed 120 hp at 13,000 rpm. With a dry weight of 169 kg, the R6 allowed up to 56 degrees of lean angle in the race trim without touching down.

For the model year 2000, the oil scraper and the shift linkage were modified.

For the 2001 model year, the engine was revised (changes to pistons, connecting rods, manifold pipes, ignition and battery) as well as changes to the steering, equipment and optics. The dry weight fell to 167.5 kilograms thanks to the lighter starter battery.

In 2003 the R6 was completely redesigned. More than 90% of the engine parts have been changed. The most important modification is the 38 mm multi-point manifold injection , which replaces the carburetor technology. The new engine continued to deliver a nominal 120 hp at 13,000 rpm. What was new, however, was that there was noticeably more power available from 4000 rpm. On the chassis side, the R6 received a new die-cast aluminum frame and lighter 5-spoke rims. In addition, 4.5 kg could be saved compared to the predecessor. The new R6 weighed only 189 kg with a full tank.

For the 2005 model year, the R6, type RJ 095, received a final revision. The most noticeable change in addition to the redesigned, sharper rear section was the use of a 41 mm upside-down fork , on whose fork feet the brake calipers were now bolted radially. The operation of the front brake, which has been enlarged in diameter, has also been switched to a radial brake pump . The front tire now had the usual size 120 / 70-17 (instead of 120 / 60-17), the rear suspension strut linkage was modified. On the engine side, the update included suction pipes enlarged to 40 mm in diameter and redesigned intake ducts.

In 2006 the R6 was completely redesigned again. The revised engine now had a nominal output of 127 hp (133 hp with ram-air effect) and a maximum speed of 17,500 rpm. In real terms, however, these values ​​are somewhat lower (approx. 122 hp at 16,200 rpm). However, the disadvantage of this short-stroke, speed-oriented design is that the new engine generates less power and torque in the lower and middle speed range, which is of secondary importance on the racetrack, but noticeable in a negative sense when driving on country roads. A special feature of the new motor is that the throttle valve is operated by an electronic servomotor ( drive-by-wire ). However, the throttle valves are still closed with a cable.

Further features of the new model series are the titanium valves , two injection nozzles per cylinder, forged pistons , lighter flywheels, titanium rear silencers with EXUP exhaust control and an anti-hopping clutch . The chassis is designed to be front-heavy; 52.5 percent are carried by the front wheel. It is noteworthy that the type RJ095 in the 2005 configuration was continued to be sold by Yamaha under the designation YZF-R 6 S until 2009.

The 2010 model has been revised and optimized in some points: There is a newly programmed engine management system and a modified rear silencer.

With the 2017 model, the R6 was adapted to the design of the new R1. Furthermore, the traction control in 6 stages and the automatic gearshift were introduced. Due to the Euro 4 emissions standard, there are losses in horsepower and torque.
