I was cookin' on that vid & I was probably going around 40 mph going down hill until the turn when I let up a little...:shock:
Going on the flat surface the 52cc engine can easily do 35 mph at a safe RPM level...
I have clocked myself with an accurate speedometer at 45 mph... NO JOKE... When I was doing this speed it was on a long and straight steep decline and I almost blew the cylinder but I didn't... I most definitely was at the 6000+ RPM level and this is NOT Recommended but it sure was exciting!!!:evil:
