QJ Motor SRK 421 RR supersport launched in Europe with 78 bhp inline-four engine

QJ Motor has taken the wraps off a new inline-four supersport motorcycle for the European market, with the Chinese motorcycle giant looking to strengthen its presence in the region. Called the QJ Motor SRK 421 RR, the new model enters the middleweight supersport segment and is positioned as a more accessible alternative to established Japanese rivals such as the Kawasaki Ninja ZX-4RR.

The motorcycle brings a radical look with its heavily forward-biased stance. The front fascia carries dual-LED headlamps up front, with a central intake and a windscreen. The cowl blends into the layered side fairings before leading to a sculpted fuel tank and an upswept tail-end with a split-seat configuration.
