Just an FYI for other Baja owners reading this thread. The death wobble that occurs from 65-85mph is gone now that I put a Michelin T63 on the front. My bike currently has 110 miles on it. I bought it two days ago. I can now go up over 100mph smoothly. Grooved pavement also didn't upset the bike. I still plan on a steering damper for riding in sand and better control in rock gardens. I had a Scott's on my 640 Adventure and I loved it.
