I agree Yamaha and Honda are about the same for reliability and our 1999 Griz has over 4500 kms and not one thing has been changed on broke on it and while I was riding in some Bush his quad was the only one that broke because his stock front shock busted guess what he was riding a Honda 1999 300 4x4 and I sure haven't heard any more annoying "Honda's are better ride red" chants from him anymore but on the other hand my 1995 Warrior has been a piece of junk and has broke A-arms, front shock, rear disc. so I guess I would have to say that all companies quads are about the same for durability except Polaris.

It was A JOKE PEOPLE, But I did check it does have a 72x72 Bore And Stroke. Maybe next time ill just say it has Square Sprockets or wheels. So Its obvious. By the way the oval piston 2 stroke bikes where the most powerful engines of their time. just look them up.

 

A 400ex just feels like a Warrior on steroids with kick-a$$ suspension.
