We will release in the next days a new ultra tuned version of 721 Superveloce. This monster tuned engine is a limited edition of only 300 pcs all around the world. This is the same engine used by our Factory Team at the Worlds together with 2113 X-one pipe (not included in this kit). Compared to the standard 721 Scuderia this new engine features a further modification to the crankshaft and sleeve by Mario Rossi.
