ColinPybus Posted May 11, 2022 Report Share Posted May 11, 2022 Hello everybody, just bought my first trials bike to refurbish, an Ossa 250 I think with engine no. M231638. I've looked online and all I've found are engine no's. beginning with B. I couldn't find a number on the frame. Any help much appreciated.

woody Posted May 11, 2022 Report Share Posted May 11, 2022 It's a 1975 250 MAR MK2, the engine and frame numbers are the same, just that the engine is prefixed M and the frame B. The frame number is on the headstock, maybe hidden by layers of paint as the original frame colour is silver/grey with white tank/sidepanels and green stripe. A previous owner has painted it all green and black engine/forks to look like the 1979 version Quote Link to comment Share on other sites More sharing options...
