I've taken an interest in these crfs. The reason I like them is cause they still have the light and electric start and such that I use. I primarily ride open fields and sometimes trails or on the road as I live on a farm. I never race on tracks. Will the crf require a lot more maintenance than the drz? I know the engine is identical to the crfr counterpart so I'm wondering if I should hold off for a while. I really don't want an mx kind of maintenance after being used to my drz. In the 10 years I've owned it I've only had to change the oil and clean the air filter. Also, in terms of performance. Would the crf have a lot more balls than the drz?
