In the winter of 2001 M3 Racing factory in Hawley, Minnesota hand built 4 replica Honda CR750 racers. Each of the Hondas featured upgraded engine bits and suspension tweaks similar to their game changing CR750 M3 Racing “works” machine that Adam Popp rode to 6 Daytona wins and two AHRMA National Championships.
All of the bikes have been sold off ($22,000USD each) including the works race version which now lives in a private collection somewhere in the UAE. The video below was shot by motor sport film company Clash Productions as a “behind the scenes” doco of a shoot done by Crank & Piston.
