|June 1967 Cycle magazine|
Basically a modification of a Villiers 250 engine, the Cycle article states that this engine design by kart engine expert Chris Merlin utilized a new right side engine case casting, incorporating a disc valve, carb mount and ignition. A modified Greeves Silverstone cylinder topped the cases and the crankshaft was a modified Alpha unit. The bike also used a custom spine frame by Frank Higley, presumably the FH in the name.There does not appear to be any info on this bike online, despite mention in the article of units being offered for sale. Were any actually sold?
