I have news from Richard Oakes at Blackjack that an exciting new derivation of the Blackjack Zero has been introduced for 2008 using the Moto Guzzi 1100 V Twin engine.
Richard explains that:
... As before, and unusual for Guzzi engined trikes, the Blackjack is front wheel drive maintaining all the handling, ride and safety benefits. We think that this alternative package will be of particular interest to traditionalists and V Twin petrol-heads.
More information will soon be posted on the Blackjack web site at http://www.blackjackzero.com/mainindex.htm
