Yamaha has FINALLY launched the R3 in India (once again) and we’re very excited for it. And that, combined with the recent launch of the Aprilia RS 457, means we just HAD to pit the four best bikes in this segment – the KTM RC 390, Kawasaki Ninja 400 and the aforementioned two – against each other to see which one comes out on top. Here’s how that went:

There is a very clear winner here (at least on paper), and it’s obviously the Aprilia RS 457. Its displacement advantage means it makes the most power and torque here. And even more importantly, it makes its peak torque at 6700rpm – the lowest of the lot – which should ideally ensure ample bottom-end grunt without compromising its top-end whack. That very characteristic can also be seen in the RS 457’s near square (almost identical bore and stroke figures) engine configuration, as that offers an ideal balance between high-end power and low-end torque.
Both the Japanese bikes are high-revving ones and you will need to rev them out to make them feel exciting. The RC 390 is rev-happy too, but with all the updates its engine got last year, its torque is much more spread out, so it now feels a lot more tractable and versatile. More about that in our real-world road test review.

While all the bikes are pretty closely stacked here, the RS 457’s preload adjustability for its fork should give it a slight edge over the other three. Riders of varying weight should be able to tune it to find the perfect setup for themselves. Interestingly, the R3 also packs the skinniest rear tyre and during our first ride last month, we found its tyres to be a bit lacking. So if you’re a serious rider, we recommend a tyre upgrade.

The Japanese bikes come out as the more practical ones of the lot with their low seat heights, manageable kerb weights, and big fuel tanks. Now, yes, the Ninja 400’s 140mm ground clearance might be a bit concerning but we found it to be ample for most situations when we tested it out last year.
The elephant in this room, then, is the RC 390’s 835mm seat height, which seems very daunting on paper, especially when you compare it to that of the other three. That said, every time we’ve ridden it, even the shorter boys have been comfortable enough, so it isn’t something worth worrying about.

Unsurprisingly, the Japanese bikes have turned out to be the most old-school of the lot. Both, the R3 and the Ninja 400, get none of the fancy electronics. The R3 doesn’t even have a slipper clutch, something that’s considered standard equipment in this segment. And it’s even funnier when you realise that the R15 V4 (a bike with half the R3’s displacement) offers a TFT console on its top-spec variant, an accessory quickshifter, and traction control, a slipper clutch, as well as VVA (Variable Valve Actuation) as standard fitment.

Here, surprisingly, the Japanese bikes are once again similar, but in an unpleasant way; Owing to them coming through the CBU (Completely Built Up) route, they’re the priciest of the lot. While the Ninja 400’s Rs 5.24 lakh price tag remains inexplicable, even the R3’s Rs 4.64,900 price is quite hard to justify. Yes, it’s coming through the CBU (Completely Built Up) route but the Aprilia RS 457 packs a lot more (on paper) at a much lower price, which is all down to the fact that it’s produced locally at the bikemaker’s facility at Baramati, Maharashtra.
And finally, if you’re on an even tighter budget, the RC 390 is not only arguably the best single-cylinder bike in its segment, but at Rs 3.18 lakh, is also pretty good value for money too (all prices ex-showroom).
