The Valiant was a sportier overhead-valve development of the air-cooled LE flat twin, with higher compression, two carburettors, a four-speed foot-change gearbox and a modern telescopic fork and swingarm chassis. Power rose to about 12 hp from the LE's 8. It cost more than rival 250 singles and sold poorly, with only about 1,600 built.
