Feast Your Eyes On This Carbon-Fibre Goodness From Kawasaki

Long before the Kawasaki Ninja ZX-25R was unveiled at the 2019 Tokyo Motor Show, there were already rumours floating around about the bike’s power output. Estimates ranged from 40PS to a scarcely believable 60PS. Now, we’ve come across some images that could give us a more realistic idea of the bike’s performance figures.
Pictures of the 25R’s instrument cluster show a stratospheric 17,000rpm redline! Implementing an inline-four configuration at this displacement range means tiny cylinder bores, pistons, con rods and so on, which means very low rotational inertia. Each piston’s stroke length will also be similarly miniscule, and these factors combine together to make this astronomical redline possible.
So now that we know how high the 250cc motor can rev, we’re in a slightly better position to estimate the power output. Looking at dyno charts for larger capacity inline-4s, it’s reasonable to assume that peak power will arrive around 1000rpm before the redline, at roughly 16,000rpm. Considering the motor’s displacement and configuration, we think peak torque will be in the range of around 24-25Nm, but this will be produced earlier in the rev range. At 16,000rpm, torque will have trailed off a little and we can presume that the motor is producing about 20-22Nm.

While all this sounds very exciting, we must remind ourselves that it is speculative, and we can’t be sure of anything until Kawasaki releases official figures and even more so once the bike is put on a dyno. Until then, we just have to keep our fingers crossed and wait.
