What is this?

I saw this at Squires today. What sort of blade is this. How old and how much?

 

Evo blade, a good one roughly 15-20k and about 20 years old.
Blue printed engine magnesium wheels full race system,roughly 160 bhp

 

Thank you very much.Notice the weird grey things going into the petrol tank.

 

Straight into the air box I think? They made the evo to celebrate 100tt wins also in limited numbers lovely bike and haven’t seen many actually on the road

 

Thanks

 

Never ever seen one just heard about them , looks great
