Let us draw a rough estimate on the performance front of the two motorcycles.

The 0-100 acceleration figures of the KTM Duke 390 have been estimated at close to the 6 seconds mark- thanks to the following video posted by Austrian Online Motorcycle Magazine 1000 ps. Top speed has already been estimated in the region of 160 kph by journalists.

Though the acceleration and top figures of the Honda CBR400R aren’t out yet, one could roughly estimate by taking the CBR500R as a reference which cranks out 46.9 bhp (47.6 ps) vis-a-vis the CBR400R which pumps 46ps (45.4 bhp). Surprisingly the difference in cubic capacity hasn’t spelt any difference in weight. A closer comparison between the two indicate differences in stroke i.e. 66.8mm (CBR500R) and 56.6mm (CBR400R) and compression ratio at 10.7:1 and 11.0:1 respectively. And though the gear ratios of the CBR400R have been revealed by Honda, the figures of the CBR500R are nowhere to be seen. But still going ahead for the sake of estimation of the performance the CBR400R would pack in, here are a couple of video that indicate the 0-100 kph and top speeds of the Honda CBR500R.

In case it hasn’t been easy for you to calculate, here are the snapshots and you may draw your performance calculations:

Won’t be out of place to state that numbers ticking on the dyno change dramatically in real world conditions- the bike isn’t facing any wind drag in the video 😉

In conclusion, the performance graph of the CBR400R is still a secret and though many would put the Honda down, more particularly on the power-to-weight ratio- but looking at the CBR500R references, the Honda with its quick spinning parallel twin might manage to put up a good fight against the Orange Mantis.

Pricing is going to play an extremely crucial role. Assuming that if  the performances of both the motorcycles are on par with each other, what premium would you pay for the CBR over the Duke if you’d wish to go for the Honda? Or it’s just the Duke for you, and the CBR400R just doesn’t matter?

    you didn't happen to check the number of teeth in the front and rear sprockets in both the bikes mentioned above. duke 200 is extremely short-geared and that limits its top speed and also necessitates an extra gear shift,hence the difference in 0-100 time. just plonk in a 40-tooth rear sprocket on the duke and drag again, you'll know what duke is made of:)

    This looks more like a touring bike and by just putting a “cbr” prefix or “r” suffix on touring bike will not make it a “sports” bike.

    KTM doesn’t have any Service Station, though Bajaj is still doing the Servicing of those Bikes.

    Its all about what you want. If you want to do long trips, Honda 400 will be the best option among the two because you never feel any wind blast. The super comfort handling and sitting portion will give you ultimate pleasure.

    If its locally with high crowded areas, then DUKE will be the best. Due to the Naked version it will be easy to do Cornering and the short pickup will help you to go ahead of HONDA.

    CBR250R is faster than the Duke 200 because of the better torque numbers.. CBR – 23Nm Duke – 19Nm The 50cc advantage does make a difference.

    However, Duke 200 ( 3.3s ) is faster than the CBR250R ( 3.6s) from 0-60

    Maybe the same will repeat in the case of Duke 390 and CBR400 too.. Im guessing the Duke 390 will be quicker to 100 but after that the CBR will have the better top speed. As the speeds cross 150, Aerodynamics play their part.

    I would rather wait for the KTM RC390. I’m sure it will be launched around the same time as the Honda CBR400R. Both will be faired offerings and will most likely be priced closer to each other, so let us compare both when the time comes.
