This is the Vincati that Sid Biberman and his son Mathew built together. A truly amazing accomplishment that married a Ducati GT chassis to a Vincent Rapide full race spec engine. There has been much written about this bike and you may want to pick up a copy of Mathew Biberman's book "Big Sid's Vincati". Jay leno also did a show with an interview of both Big Sid and Mathew which is worth watching.
