Around 1991, I campained a Honda NS50 in the CMRRA(Calif. Mini Road Racing Accosc.)and since they placed it in the modified class when it was stock(it was one of the first, big wheel, liquid-cooled minis), so I procceded to modify it. During the course of that season and the next I added a KX 60 piston(bringing displacemnet out to 58cc), CR80 ign., trans, clutch and intake. The pipe was custom hydra-formed and the chasiss was much modified and resembled the early Aprilla RS50. Tires were used Michelins off the frt. of Honda RS 125 racer(given to me by Rodney Fee).
It was clocked w/radar at Streets of Willow(up the long start straight)@ 71 M.P.H. The Honda Optional analog(cable-driven)tach burried @ 15,000 r.p.m.
I was racing w/ a then 11 year old Johnny Hopkins and we thought about regearing it for him and giving some speed records a shot, but we were having too much fun going around in circles.
I often read about top speed numbers for minis that make me groan, but the content of this article nicely shows what it takes to get into the 70′s m.p.h. w/50cc’s and beyond. Well beyond
