Yamaha Offers to Buy Back New R6
By MCUSA Staff
The motorcycle world was awed when Yamaha announced that its radical
new YZF-R6 sportbike had a 17,500-rpm redline, getting near to the
lofty rev limits of Formula 1 high technology.
Well, it turns out that a streetbike engine revving to 17.5K is still
nothing more than a dream. Independent dyno testing has revealed the
R6's rev limiter kicks in shortly after hitting 16,000 rpm.
In response, Yamaha has announced its error in that its tachometer
reads about 9% too high, showing 17,500 on the tach but not in
The following is a release on Yamaha's website:
"Yamaha introduced and marketed the new 2006 YZF-R6 motorcycle with a
red line limit of 17,500 rpm, as indicated on the tachometer. After
testing production units, we have determined that the actual red line
limit is approximately 16,000 rpm, resulting in a tachometer error of
roughly 9%. This has no affect whatsoever on the performance of the
While the R6's performance remains, there may be some buyers who
bought an R6 in part because of its racy redline. For those people,
Yamaha has sent out letters to all R6 purchasers offering to buy back
their bikes (plus interest) if they are dissatisfied.
"We decided we'd better do the right thing and step up and put our
money where our mouth is," explained Yamaha Motor Corp's press
relations manager Brad Banister.
The R6 buy-back follows a similar precedent set in the car world when
Mazda offered to buy 2004 RX-8s from owners once the claimed 247 hp
of the manual transmission version was found to actually measure at
238 ponies. Automatics were downgraded 10 hp to 197. The difference
here is that Mazda was forced to make this offer, while Yamaha is
doing it voluntarily.
"It's an unprecedented thing in the industry," Banister added, "and
it shows how committed Yamaha is to customer satisfaction."
In fact, this over-clocking of factory tachometers has been going on
for some time. Yamaha's previous R6 was claimed to rev until 15,500
rpm, but our dyno testing proved that it hits its redline prior to
And this isn't uncommon in the world of sportbikes. Last year's
Kawasaki ZX-6RR claimed a 16,500-rpm redline but revved to less than
16K when we put it on the dyno.
Yamaha hasn't publicly announced the reason behind the tachometer
discrepancy, with Banister explaining that the cause is yet to be
determined. He added that Yamaha doesn't expect to be flooded with R6
buyers trading in their new bikes.
"The R6 is exactly what we said it was - the most awesome, the most
technologically advanced 600 ever built."
