Who Wants a 102 Horsepower 500cc Two-Stroke Kit Engine + Video


For all the die heard Honda fans who are still bitter that the OEM never put it’s potent CR500 two-stroke engine in an ATV chassis, your day of jubilee has come. Panthera Motorsports, a Canadian engineering and manufacturing firm, has developed an electric start, 500cc two stroke engine capable of producing 102 horsepower that will bolt directly into a Honda TRX450R chassis. The PM07-18 will set you back $6080 for a version with either electric start or a kick start or an option with both electric and a kickstart can be had for $6400.
Check out a promo video for the engine below as well as a clip of an ATV on the dyno.
