Ooh Supermono's!Proper racing bikes,I love 'em.
Raced two of 'em in the early '90's.First one had a 500cc Rotax motor.Great bike to get me started,..untill a big 'ol hiside at Mallory broke it in half!

Rebuilt the bike,then the gearbox fell to bits at Snetterton and wrecked the engine.Sold the rolling chassis and bought a 640 Rotax from Gary Cotterell(GRC).Had a good season on it,then a crash at Cadwell ruined it.

(Bit of a pattern forming here!

)
Eventually rebuilt the bike and loaned it to Sandra Barnett who finished 10th at the TT in 1995.
Still hang my nose over them when I see them.
twpd is right,..those MuZ Skorpions are not to be sniffed at.The racing version was a lovely bike.(I think Tigcraft designed the chassis.)I seem to remember the German girl Katia Poensengen doing very well on them.
