My son has out grown his crf80 and wants a cr85. I ride a kdx200 and he thinks the 2stroke sound and power delivery is great. The problem is we trail ride and hill climb, while the kdx is great for this, I'm not so sure about the cr85. I told him I thought this is more of a race bike and he might be disappointed with it. I guess my question is can a cr85 be tuned to trail ride and give good low end grunt and not foul plugs if lugged up a hill or two.
