The bikes have barely made it in to owners hands and rumors are flooding the web that Aprilia is recalling many RSV4s and RS4V-Rs to address "a potential engine failure due to the identification of a batch of components that do not meet quality standards."
I guess the engine failures experienced at the moto journo testing at Mugello late last year were not a fluke and it's got Aprilia scared.
The reported remedy? Replace the entire engine. Ouch.
Stay tuned for more info.
