So, I'm looking at an '09 CRF450X for trail riding. I'm familiar with older bikes, XR's, CR's and the like but don't have any experience with these CRF's. Besides the usual stuff, worn suspension, chain, sprockets, fluid leaks etc, is there anything in particular I should be looking at? Common failures? The bike is supposed to have a Hinson clutch. I imagine the only way to confirm that would be to pull the clutch cover? Any help or advice is greatly appreciated.
