Hey if quality machine work and material procedures are followed there's no reason Chinese scooters can't perform,,, it's the unscrupulous manufacturers and dealer/ vendors that perpetuate this nonsense,,, it's getting better by leaps and bounds,,, I'd have a zongshen rx3 in my garage as I type if they made a 450
It's a multiple part problem, Pete. The director of Qiang Jing, owners of Benelli, explained that the the new BN-302 motorcycle was overbuilt because high quality metal isn't readily available in China. Also in the early part of this Century importers of Chinese scooters were people like Pep Boys and Costco and only interested in a profit. They speced cheap over quality. Things are different now but the public long remembers the bad over the good.
Even at that the GY6 engine in a 150cc was originally designed as a 125cc to meet the laws of other nations so it's stressed already out of the box. The 50cc engine was designed as a 72cc and debored to meet the "No License Required" for a 50cc in most places. Some people sneak out a Secret 62cc version but at that the 50cc GY6 is the stronger motor.
Ridden carefully they will all last, even the Costco Specials. Sadly there are too many people who don't and blame the scooter.
