Hello, I'm just returning to owning a trials bike after a gap of 30 yrs or so! Yesterday I bought a Bultaco that has also been away from the sport for a similar amount of years. The bike has frame number B 9202989 and engine PM9101464. The frame has the aluminium bash plate instead of bottom tubes. The tank and seat/side panels are one piece molded with ribs on the side panels. I'm not too worried if the bike is a bitsa but would welcome any info on what I've bought.

The frame is from the M92, the first 325cc bike from 1972/s, the engine is from the M91, the 250 version.

The bashplate is a conversion as the M92 had a full cradle frame with tubes running under the engine

Tank/seat unit as per original.

Thanks for the info on the frame, I was a bit confused by the bash plate as it looks to be a very tidy conversion (just as well). What colour would the frame have been?

This frame mod was common copying the Miller hi boy frames some were well done others were bodged it gave more ground clearance The frame should be silver
