There’s a reason middleweight four-cylinder sportbikes simply refuse to die. They hit that sweet spot where performance feels exciting without being overwhelming. Plus, the sound a four-banger makes is simply iconic, and most middleweight sportbikes are sensible enough to be ridden on the street.
For decades, this space was ruled by Japanese brands, with models like the Honda CBR600RR and Kawasaki ZX-6R proving that you don’t need superbike numbers to have a great time. Riders love them because they’re fast enough, smooth everywhere, and a lot less intimidating than full-on liter bikes. But recent years have shown that Japan's big four have been shifting their focus onto more compact machines. Particularly, bikes with twin-cylinder engines.
But here’s where things get interesting. Chinese manufacturers like Kove and QJ Motor have been launching four-cylinder sportbikes left and right. And no, these aren’t budget commuters pretending to be sporty. We’re talking proper inline-four engines, aggressive styling, modern electronics, and price tags that usually undercut the established players. A lot of Chinese manufacturers are already in the mix, and they’re forcing everyone to pay attention.
