Just curios what you guys recomend for tight technical woods riding. I am thinking of changing sprockets all ready since I will never need 5th gear at my age. What about a trail tech heavier flywheel? That was a mod that made a big difference on the old CRF450R but this KXF seams like it will lug and chug around the tight single track switchbacks just fine. What have you guys found? Any other woods mods I should think about?
