Fully agreed... I like 2 strokers and I run a built up China Girl engine, but there's no substitute for the torque a 212 can put out, and the engines I was refering to were the KTM and Morini type that make good top end power but they only make about 2 ft/lb torque... Yes, they are strong when in their powerband, but a big 4 stroke with less horsepower will win just about every time because of the wide powerband and fat torque curve. Now a 200cc 2 stroke with 40 horsepower will beat a 212cc Pred, but not a 50cc 2 stroke with 9 horsepower...
