The friends at MCN got their hands on the spy shots of the new Aprilia Tuono V4 and RSV4 R models and it looks like the bikes are very close to being launched. Both have been spotted during tests undergone on the Mugello track in Italy.

Although none of the two bikes is revolutionary, both being based on the Aprilia RSV 4 Factory, these photos reveal a few essential details.

The RSV 4 R model will follow his RSV 1000 R sibling, meaning that it will have cheaper parts than on the Factory. Affordability was a priority and, given the fact that the RSV 4 Factory now costs around $18,000, we can expect the R model to compete with the 2010 BMW S1000RR.

In order to reduce costs, Aprilia goes for Showa suspension instead of Ohlins, less exotic rims and gives up to different carbon fiber bits and pieces, but do manage to retain the Brembo monoblock calipers.

The Aprilia Tuono V4 carries on the tradition of the naked models built at the Noale factory, meaning that it features stripped bodywork, straight handlebar and a strange looking headlight.

Given the fact that this year’s Paris Moto Show was canceled and the next Intermot edition in Germany is scheduled to take place in 2010, the Italians are left with an only option to launch the new models: EICMA 2009.
