Greg Robertson, a Southern California Pro, started his career at age 10 when his father bought him and his older brother a Minarelli motorcycle.  His first race was at Bay Mare Cycle Park at the age of 13. He won the first moto but DNF’d the second.  Over time, Greg became a well know rider for Mid Valley Cycles in Van Nuys, CA. Campaigning a 125cc CZ with great success.  Greg was probably best know for his win at the Snake River MX in 1972.  Riding a custom 125cc CZ, Greg beat some of the best in the sport including Brad Lackey, Tom Rapp, Ken Zahrt, Bill Silverthorn and Tim Hart to name a few. Greg got a coveted Factory CZ ride in late 1972.  That Factory CZ is featured here.
