I run CRF450 it's 02 model . The engine oil is less than QT. Same for the trans It also has very small oil filter. For me I change oil very race. And do the trans and filter very other race. For a engine that carries less than 800mil's of oil. I like the piece of mind running clean oil. There a lot of demanded for the oil to cool/lube the engine for less than a QT.
