I've had a blackbird for a year now, and have to say, this is the bike I have been looking for, for a very long time. There is very little negative to say about it, and so much positive stuff. It's power and performance is sublime and effortless. it is creamy smooth, with no throttle snatch. It's comfy, resonable mpg,150 mile + range, fantastic build quality that makes even older ones look like new, it's reliable and you never ever doubt that, it screams like a CBR should when caned and is a very scary bike when the throttle is opened, but it will also trickle along at 30mph without a hitch.
On the down side, the handling is not up with todays sports scapels,it is a heavey bike, and is best left to the fast sweepers, the equipment is basic - what just what you need, and no more, and the mpg is too easy to get below 40mpg. Legs slightly cramped (i'm 6'1") and I need a solution to that.
Having said that, the only bike I would replace this with is another blackbird. why did I wait so long to try one.
