| Despite SOS (Sound of the Singles) racing virtually disapearing here,its still very big on the continent.Basically the rules are,the bike has to be a four stroke single and thats it.Anything else goes.I think they have recently separated the water cooled bikes from the air cooled.It opens up the doors for all sorts of wacky ideas,ie fuel injection on old trailie engines and carbon fibre frames.I saw a lovely Husaberg MX engine in a 125 Aprillia GP frame.Just heavier than the average pushbike!The UK series had several differant frame builders and 'works' teams,Tigcraft,Hejira and Harris to name a few.Of course Ducati got into the act by making the fabulous Supermono.
I guess these Dutch "supermono's" could be fun on the right (twisty) road and track days.(Ask Monty about his Gilera)The frames seem to be made of thinner tubing and would be very light weight.Hence the single disc brake.
Not much fun on the motorway tho! |
