Supersport R6

The fact that Yamaha again failed to wrest the Supersport World Championship title from Honda in 2008 was probably not due to the motorcycle. The factory R6 prepared in Germany drives like a Grand Prix racer for the Moto2 World Championship? which won’t come until 2011.

Six titles in a row ?? Honda’s dominance in the Supersport World Cup from 2002 to 2007 seemed set in stone. But at the start of the 2008 season, it looked as if Yamaha could break the series of successes with the new YZF-R6: Broc Parkes won the first race appearance of the new 600, previously teammate Fabien Foret had set the R6 training fastest time. But in the course of the year Parkes did not manage to confirm further training triumphs in the race. And Foret was so badly injured in a crash in Brno that he was out of four races. The end of the song: fourth and sixth place for Parkes and Foret ?? and another title for Honda.

The invitation to a test drive on Forets at Yamaha Germany in Neuss prepared factory R6 on the day after the season finale in Portimão, Portugal was exclusive ?? and especially attractive because Ronald ten Kate, head of the world championship winning team, generously allowed me to ride his glorious Honda CBR 600 RR in direct comparison. An informative comparison. Because the CBR clearly turned out to be a shrunken superbike, with strong torque-oriented power delivery and a lot of pressure in the middle speed range. The R6, on the other hand, looked like an anticipation of the successor class for the 250 cm? Two-stroke GP racers as we imagine it: small, compact, agile in steering maneuvers, hungry for revs and also with higher peak performance in the upper rev ranges. The weaknesses of an engine designed in this way at medium and low speeds compensate for the YCC-I intake system, which changes the length of the intake funnel? depending on the engine speed, the gear engaged and the position of the throttle grip.

The hilly nature of the Portimão circuit made the differences between the Honda and the Yamaha even more apparent. While the CBR 600 RR can be catapulted out of the curves from 9000 rpm, the YZF-R6 wants to be driven more like a two-stroke? usually a gear lower than the Honda, with 11000 rpm if possible at the apex of the curve, so that there is enough power at the exit. In the five-digit range, the R6 then turns up to the shift point at 15500 rpm much more quickly than the Honda and can thus exploit its performance advantage at high speeds on the straights. A number of technical refinements leave no doubt: The R6 brings MotoGP technology to the Supersport World Championship. And gives a foretaste of what the Grand Prix 600s, which will replace the 250 two-stroke engines from 2011, could look like.
