As much as I hope nobody on my team hears me say this... From my point
of view, Yamaha race engines are more durable than Honda, Kawasaki, KTM
and even our beloved Suzuki, IN MY OPINION in the last few years. Some
other manufacturers such as Gas Gas, a Spanish motorcycle, are now using
Yamaha engines...

Back in the '70s, if you wanted to have fun you rode a Yamaha dirt bike. If you wanted a better handling, faster bike and didn't mind working on it some (and had the cash), you rode a KTM/Penton. One of the best handling enduro bikes I ever rode was a Maco 250. A bit heavy, but a great bike. The guy also had a Maco 400. It was a beast.
