Styling patents have emerged that show Aprilia's finished RS660 for the first time. Initially unveiled as a concept at Eicma last year, the finished bike is a very faithful version of the radical machine we saw last time.
Powered by a 660cc parallel twin, that’s effectively the front bank of cylinders off the V4 powerhouse in the RSV4 1100 Factory, Aprilia are hoping this machine can help revitalise supersports bikes for a new generation of riders.
Aprilia claim they opted for a twin layout for its efficiency and compact nature, alongside the freedom that it left the designers to create a lightweight frame that uses the engine as a stressed member. The clever rear shock has remained, which is mounted between the swingarm and frame without a linkage to help shed a few extras pounds.
Despite its sporting credentials, the Italian firm also claim that the RS660 gives a comfortable riding experience, thanks to a large seat and sensibly-placed foot pegs, as well as handlebars placed above the top yoke to remove excess weight from your wrists.
Although we can’t see the specs of the finished unit the parts all look like the latest crop of sports bikes, so it ought to be a fine machine albeit perhaps with a hefty pricetag. With only the Kawasaki Ninja 650 as an obvious competitor, it could do rather well. We’re expecting Aprilia to unveil the finished bike at the EICMA show in November.
