Fully agree there Erno, Motor makes a lot of errors with these test-data (another Dutchy here).
Not only that but they gather their data via a datalogging system with wheel speed sensor on the front wheel for which they input the front tire's circumference (they "measure" it themselves, my guess would be that probably using the numbers for same sized Metzeler from their tyre-bible would be even more accurate?) and then they use a guessed percentage of tire-growth at high speed for the top speed measurement.
Contrary to some trustworthy German and English mags they don't use timing-lights or radar-guns or whatever.
And then they also complained a lot that it was close to impossible to keep the front wheel on the ground, so what does that do for dependable data from the sensor on the front wheel.
I'm subscribed to this mag for over 20 years and by now I know the value of their data far too well.
BTW, couldn't care less if ZX-12 was quicker/faster/whatever more but these guys are incredible in the negative sense with posting 0-100 km/h in 1.9 second.
Anyone can see that this is nonsense!
(that's 0-62 mph or something to most of you)
