Jeremy from MX tech , knows his stuff, he valved Eron Ezerins RM,s he always won 125,250 a class everywhere, Red Bud, Lake Geneva s. cross, nuclear series, RedBud national cleaned house on the night track, then qulified on the natl. track on a stock rm125. His suspension looked better than the factory riders, his bike sounded super weak compard to other riders. Setting the sag is the most important setup thing, I like alot of sag on a 125 for stability and to get the front wheel light to get on top of the dirt. My cr125 says 95-100 in the book, I run 108-110 of sag, factory connection says 110 mm sag.
