Not sure about that 900 ACE either. Cost just $500 less than the 600 E-Tec and puts out just 90 HP.
E-Tech 2 stroke technology is truly amazing. The amount of oil it burns is very small compared to yesterdays 2 strokes.
In a comparison, I don't really know how many actual miles we went, but over 2 days of riding I filled up my gas tank 4 times and the oil once (Almost a full gallon of oil burned.) compared to my buddy running an e-tec that decided to top off his gas tank because he wasn't sure he'd make it back and his oil reservoir was darn near in-measureable. Maybe 1/2" down from when we started, which would be about 2 ounces. I was riding a 1995 Summit 583 and he was running a 600 e-tec in a MXz.
