Patent photos have surfaced supposedly showing Kawasaki’s upcoming supercharged 600 cc four-cylinder, dubbed within the Akashi City, Japan, company as the “R2”. With the current model Ninja ZX-6R due for an update, could this force-fed four be its replacement?

What can be seen from the patent drawings from website morebikes is that the R2 draws a lot from the current Kawasaki hyperbikes, the H2 and H2R. A trellis frame can be seen in the top-down drawing, with the inlet for the fuel tank perched above the airbox, and extending downwards under the rider seat.

A flow chart shows the process flow of the intake and exhaust, with the fuel pump feeding what looks to be a multi-point injection system, with an exhaust valve indicated which might function in a similar manner to Yamaha’s EXUP exhaust system.

Exhaust position has changed, going from the side-mounted can on the current model ZX-6R to an underseat unit. The swing-arm, assuming this makes it into production, seems to be a welded aluminium alloy affair, unlike the massive forged unit on Kawasaki’s current model 600.

The fairing on the R2 also looks to be a development of the current unit found on the Kawasaki ZX-10R, with a large nostril inlet cutout and rounded headlights, as opposed to the angular half-fairing found on the H2. Brembo brake calipers also look to be present at the front end, based on the side-view illustration

Certainly the patent drawings look interesting, and might lead to the R2 being the “baby” H2, albeit with significantly more power output than the current model ZX-6R. With Euro 4 looming in January, it comes as no surprise that more manufacturers will be looking to forced induction to conform to emissions testing.

What do you think? Is the supercharged R2 the way foward for Kawasaki’s inline-four 600 cc supersports bike? Or might this be a “baby” hyperbike, designed to enter the line-up alongside the 400 km/h H2R?
