(Kevin Wing/)Normally a longer stroke might mean a lower rev limit and less outright power, but the type-approval document for the new QJMotor shows it puts out 76.5 hp, which is only a fraction behind the 500cc CFMoto’s 78 hp despite a 79cc capacity deficit. It also means the QJMotor beats the full-power version of Kawasaki’s ZX-4RR, which manages 74 hp in some markets (but is limited to 56 hp in the US). What’s more, the QJMotor SRK400RR promises to be lighter than its rivals. The type approval shows a ready-to-run curb weight of 388 pounds, which compares well against the 415 pounds of Kawasaki’s ZX-4RR.When it comes to other information, the type approval reveals that the bike’s wheelbase is a tight 54.1 inches, with an outright length of 79.5 inches and width of just 28.3 inches, and puts the top speed at 137 mph. It looks like the chassis is a steel tube frame, with an aluminum swingarm and upside-down fork—probably from Marzocchi, since QJMotor’s parent company has a deal to manufacture suspension on Marzocchi’s behalf via a joint venture with the Italian brand. Like other QJMotor models, the brakes are branded with the company’s own name but they’re radial-mount four-piston calipers with dual front discs and ABS.The SRK400RR takes styling cues from the Ten78 concept. (QJMotor/)The bike’s styling is a shift from the designs we’ve seen on QJMotor’s current sportbike models, including the existing range-topper, the SRK921RR that’s made using an MV Agusta four-cylinder engine. For the new SRK400RR, the design takes its cues from the QJMotor Ten78 concept that was shown at last year’s EICMA event in Milan. Designed by former MV and Benelli design boss Adrian Morton, the Ten78 used another MV Agusta engine, the 1,078cc four-cylinder previously used in the F4 superbike, and featured a distinctive intake slot framed by the LED running lights lining the leading edge of the nose. The new SRK400RR adopts much the same style at the front, but replaces the all-transparent upper front bodywork with a more conventional screen.At the sides, the fairing is again like the Ten78, with smooth panels that lead back over the frame and merge into the fuel tank and tail. The seat is also straight from the Ten78, featuring the same longitudinally split pillion pad. A couple of anomalies suggest, despite the type approval for road use, that the bike seen in the paperwork isn’t quite finished. The mirrors, for instance, appear to be designed to house turn signals (like the Ten78 concept) but instead only have silver sections where those lights would go. The real turn signals are simple, off-the-shelf LEDs bolted to the fairing sides. That might well change for the full production version of the bike. With an official launch unlikely until toward the end of this year, there’s certainly time for some tweaks, but the SRK400RR already looks like it could be another intriguing machine to keep an eye on.
