TIt was on this day that Bri­tish mo­tor­cy­cle man­u­fac­turer AJS an­nounced it was to add the Vil­liers pow­ered tri­als ma­chine to its model range. With the Span­ish Ar­mada of ma­chines from Bul­taco, Mon­tesa and Ossa chang­ing the buy­ing trend of the gen­eral pub­lic, the com­pany de­cided the time was right to fight this with its new model. o de­velop a new ma­chine you ob­vi­ously need good rid­ers to as­sist and for AJS this was no prob­lem as they had the tal­ented Davies broth­ers from Glouces­ter, Tony and Mal­colm. Mal­colm was con­tracted to the com­pany for his mo­tocross ca­reer but was also a very com­pe­tent tri­als rider. The new ma­chine was pre­sented to the press who had known of the ma­chine’s ex­is­tence but never ac­tu­ally wit­nessed it in ac­tion. The mo­tor would be the tried and tested 246cc Vil­liers sin­gle cylin­der air-cooled Mk 37A unit. AJS had mod­i­fied the cylin­der bar­rel port sizes and shapes dur­ing man­u­fac­ture of the ma­chine. The frame con­cept was sim­i­lar to the ‘Works’ mo­tocross ma­chines which fea­tured a ta­pered large di­am­e­ter top tube with rear wheel ad­just­ment car­ried out at the swing­ing arm pivot point, which also em­ployed sealed for life polyuretha­ne bear­ings. Though based on the mo­tocross frame the tri­als one was scaled down in many ar­eas which in­cluded a sin­gle front down tube and a shorter swing­ing arm giv­ing it an over­all wheel­base of fifty one inches with nine and half inch­esof ground clear­ance. Other ma­jor com­po­nents in­cluded metal pro­file front forks with forged light alu­minium yokes and Bri­tish man­u­fac­tured wheel hubs. Pressed alu­minium mud­guards were fit­ted and a large ca­pac­ity Puro­la­tor paper el­e­ment air fil­ter sys­tem. The colour scheme was quite im­pres­sive with an or­ange glass-fi­bre fuel tank com­pli­mented by a sil­ver grey fin­ish frame. It was an­nounced that the ma­chine would go on sale through selected sport­ing deal­ers in kit form priced at £228.10. Its first com­pe­ti­tion ap­pear­ance would be at the end of Au­gust in the Manx Two Day trial with Mal­colm Davies on board. What’s in­ter­est­ing is that on the same day the Vil­liers Com­pany an­nounced it would trans­fer the man­u­fac­ture of cur­rent and other de­signs un­der de­vel­op­ment to AJS Mo­tor Cy­cles di­vi­sion. The Mk 37A mo­tor would be ex­clu­sively for AJS ma­chines start­ing with the new tri­als model.
