In production, the machine had leading-link forks on a frame with major alterations. Triumph would not supply complete engines, so they were bought as sets of spares, before Meriden stopped this from happening.
By now, Roger Kyffin was using his own frame with Ceriani forks. He tried BSA who refused to supply engines and then turned to Villiers. Using one of their engines he produced a trials model in a smaller format, but when Villiers went down, production stopped.
