The lucky bastards at Motociclismo.it have spotted the Aprilia Tuono V4 testing at a track day at Mugello, and were fortunate enough to have their photo and video cameras at the ready. At an event that feels more like a setup press leak, than a true spy capture, we still get some of our clearest views of the 2011 Aprilia Tuono V4 yet. The street-naked draws heavily from the RSV4, and has the usual differences where we’d expect to find them on these two bikes. Perhaps the most exciting is what appears to be an ABS and/or traction control system pick up on the front and rear wheels, which might be a hint of things to come in the Aprilia sport line. Check after the jump for a video of the Aprilia Tuono V4 going around the track, and more photos.
