I am going to go down to try my luck at Baja 500, and see if I can finish. I know it is not the ideal bike for that...but he's all I got. So, I am wondering if anyone can give me a heads up on the best gearing. I am going 15 up front, and something really small in back. Maybe a 40? I am going to need the bike to be able to comfortably run at high speed (100mph), so I don't just run it at super high revs and blow. Can anyone give me some ideas on the best gearing for a ride like that? This is my first time down there, and could use some advice. Thanks.
