Arter Match­less G50 Mark 4

Old Bike Australasia - - ARTER G50 MATCHLESS -

Wil­liams set­tled on a Nor­ton Road­holder front end, with twin Koni shocks at the rear, how­ever, he re­designed the left leg of this fork to in­cor­po­rate a new slider which al­lowed the AP-Lock­heed twin­pis­ton brake caliper that gripped the 10-inch (254mm) Gir­ling cast iron disc to be mounted on it, with an iden­ti­cal brake combo at the rear. The front caliper was mounted be­hind the fork leg to im­prove steer­ing by bring­ing the cen­tre of mass closer to the steer­ing axis. Over time, the space be­tween the fork legs was nar­rowed via spe­cial triple clamps, to al­low the han­dle­bars to be mounted closer to­gether to re­duce wind re­sis­tance, while dis­tinc­tive slots were cut in the flanks of the fair­ing to al­low it to be wrapped around the rider’s up­per body while still giv­ing space for the ‘bar ends to ro­tate. The chance to try that out for my­self came at tight, twisty Mal­lory Park – a han­dling cir­cuit par ex­cel­lence, if far re­moved from the fast open spa­ces of tracks like Monza, Spa and the TT Course at which the bike had ex­celled. But it was also ag­ile and nim­ble enough for Peter Wil­liams to catch and pass Ago’s MV triple in the 1972 Hutchin­son 100 run in the re­verse di­rec­tion at Brands Hatch, leav­ing the Ital­ian mae­stro to fall off in vain pur­suit of the fly­ing sin­gle. Af­ter spend­ing its re­tire­ment years tucked up in Tom Arter’s work­shop af­ter he passed away in Novem­ber 2005 the Arter Spe­cial Mk.3 was ac­quired by Team Ob­so­lete’s Rob Ian­nucci, who al­ready pos­sessed four other Arter bikes in his Brook­lyn, New York ware­house. So you might say it went to a good home – but be­fore cross­ing the At­lantic

Alan re­ceives his brief­ing from Peter be­fore tack­ling the tight Mal­lory Park lay­out. Pri­mary chain needs to be lu­bri­cated – hence the sponge.
