    I have used this drive system daily for 2 years under very severe conditions. I am heavy (280 lbs) and riding a 79cc in a hilly area. I ride all winter in snow on studded tires with low tire pressure. I tow a utility trailer to the store.
    It’s severe service, and it was smooth and thoughtlessly reliable. I’m just now replacing the clutch after possibly 10,000 miles of this harsh use. All the other components are doing great.
