The Blackbird is a great bike. My mate had one when we worked in Dubai. i had taken my 3 bikes out there as I did not want to sell them at the time. 900 Superlight Ducati; 900 Speed Triple Triumph (1995) and a Z1 with Moto Martin frame. sold the Duke and bought a Honda CBR 400RR for track days. That was super! only 55HP and 14500 RPM. So much fun with the risk of chucking yourself off when you pin the throttle!
Still have a few bike now, but no time to ride them.
The Moto Martin went to pay for the Lee Enfields (good move). Still have the Triumph; an XT500 and a 73 Z1 in bit's.
