Aprilia is adding a new middleweight contender to its lineup with the RS 660. The company released a concept version of the motorcycle at the EICMA in 2018. The company has been working on its bike ever since. There have been one or two sightings of this particular motorcycle testing, but Aprilia has been pretty tight-lipped on the specifics. Now some design drawings have come to light.
These official design drawings show a bike that looks a lot like the concept at EICMA. However, they are not exactly the same. As RideApart points out, the front forks and brakes on the concept were Öhlins Brembo Stylema calipers. The ones on these drawings look to be Sachs and Brembo Monobloc calipers. That’s not a bad thing. These components might not be quite as high class as the concept bike’s kit, but they’re still quality parts. There are also other small variations in the headlight and bodywork, but those are only slight.
With these design drawings come the official patent for the bike, which means Aprilia is serious about this motorcycle. According to MoreBikes, the RS 660 gets a new twin-cylinder engine that will make around 95 hp. It’s a far cry from the RSV4 1100 Factory more than 200 hp, but that’s the point of a bike like this. Aprilia is entering a new area of the market. I’m pretty pleased with what they appear to have.
