After a year of observation and testing we have finally approved the Avenger 85 engine that the YuanDong factory in China has been making for the past year. 

Regardless as to what some people may say YuanDong is the exclusive CHINESE manufacture of the Avenger 85 engine.  The same factory that has always made our SkyHawk line of 2 stroke engines for over 21 years.    Look for the YD logo on  the crankcase to ensure authenticity.   Other Chinese factories will soon learn to copy the YD Avenger 85 design so beware of fakes.

BECIDES BEING A STANDARD PEDAL START ENGINE All OF OUR AVANGER 85 ENGINES HAVE OUR EXCLUSIVE RIGHT SIDE FLIP WINDOW ENTRY FOR OCDT CORDLESS DRILL ELECTRIC ENGINE STARTING WHICH IS A GRU-BEE EXCLUSIVE FEATURE. 

NOTE: THE OCDT TOOL IS NOT INCLUDED IN THIS AD, SOLD SEPERATELY HERE-IN. 

The Avenger 85 52x40 is a true 85cc displacement HIGH PERFORMANCE 50 MPH Plus engine with a 52mm bore and 40mm stroke.    Yes, this engine competes directly with the Menace 85 and the Phantom 85 sold by our friendly competitors.

My Wife's retired brother inspects at the factory what you expect and yes that's not 100% perfect but it's a lot better than no inspection at all when you consider piece worker's pay is the same for making defects as it is for making zero defects.
