Nice one, here is the Original Lisa Jones 200, Danilo liked it. Tell tale sign on the "PECO" bikes was the handle of various styles on the top of the rear silencer.
Most bikes went to Local Surrey Schoolboy riders back in the day, the last bike I took to the 4-jours in Limoges back in the early 80's.
This bike built and developed by her father Mr Derek Jones, a mechanical wizard on the side.
Started life as a 125cc and was converted to a 200cc by removing the cylinder sleeve, and boring out the barrel to accept a larger sleeve and piston.
All parts used were Rotax.
Additional changes included a 900 gramme ( 2 lb ) additional press on flywheel weight, the carb' internals changed, timing cover spaced out , custom spacer for internal electrics and 320 SWM bash plate.
A whole flywheel cover had to be sacrificed by cutting the end section off to make the casing spacer..!
All original SWM no pattern parts fitted.
Forks changed to Betor.
Other mod's that some of you will recognise including a grab handle on the rear silencer( pretty essential ) and Fantic foot rests.
"PECO" is short for Performance Equipment Company in buisiness during late 70s and early 80s with an SWM and Fantic dealership. Happy Days!
This bike was tested by SWM works rider Danilo Galeazzi and modifications approved by SWM bosses who were at the 1981 SSDT.
No idea why the front wheel is on Bultaco style the wrong way round on the newer pics...!
Crazy, 38 years ago now....!
