We just got this new to us 2013 Yamaha WR250R with simple "dirt mods" with new tires and 13/50 gearing. The bike is a hoot to ride! The MT-43 rear added a bunch of rear height, ratio and traction off road from stock. The XCMH is a proven performer for dirt oriented DualSport. I was having some issue knowing what gear to be in and noticed a little "under-steer" if pushing on the pavement. The point is to get to the trails though. Tires and gearing seem good for the dirt and gravel. I preferred the stock gearing and tires for the road. We set up the stock suspension for sag and compensated for the ride height of the MT43. Everything else is stock. Suspension tweaks to come. The bike seemingly works well for me but once we ride some real dirt, we will learn more.
