Rare ‘big banger’ re­stored

The Witness - Wheels - - MOTORING - IAN GROAT

LO­CAL mo­tor cycling leg­end Dave Peter­son rode a for­got­ten era Moto GP two-stroke ma­chine at the Zwartkops Day of Cham­pi­ons last week­end.

The Pro­ton KR3 was part of a grand prix at­tack with these big-bang, three­cylin­der, two-stroke ma­chines back in the 2002 ti­tle chase.

KZN’s Rory Nes­bitt worked for over a year to get the fac­tory bike which was rid­den by Nobu­atsu Aoki. The bike is among a hand­ful of Pro­tons, all with a top speed recorded in Aus­tralia’s GP at 320 km/h and weigh­ing just 110 kg.

The fea­tured three-cylinder, two stroke mo­tor works on the big bang prin­ci­ple of all three cylin­ders fir­ing be­fore 180 de­grees.

Kenny Roberts spared no ex­pense on mak­ing the ma­chin­ery with over 50 per­son­nel work­ing on ev­ery sin­gle area of the unique GP racer.

Nes­bitt, who has pi­o­neered the bike re­build, says that it was a day to re­mem­ber when for­mer Moto GP rider Dave Peter­son took the bike on pa­rade with other “Team In­com­plete” leg­ends.


Dave Peter­son gets his 180 horse­power Pro­ton KR3 to per­form in track test­ing. The price­less bike raced Mo­tor GP in 2002 with Kenny Roberts junior on board.
