2012 Husqvarna (Husky) wr125. About 10 rides total, still on original piston so it's pretty new. RM needle upgrade (search for this if you're not familiar) and it's jetted well, crisp and good power through the rpm range. I put Race Tech "Gold Valves" in the forks which are very nice. Otherwise it's stock. I just don't ride the bike enough.
