I've been puting more time on my XR600 since I finished restoring it. I have about 100 miles total on it now. I have been on the freeway a couple of times, and it was a pretty bad experience. I could barely keep up with traffic. It sounded like the motor was peaking out and I had no more power. Don't know how fast I was going since I don't have a speedo, but it felt like maybe 50-55mph max. Anyway, after searching around, I noticed that almost all the XR600's have 14/48 gearing stock. But my 89 came stock with 14/50 gearing. This is exactly what I am running now. Does anyone know why Honda put this gearing on the 89? It has tons of low end power. I can do any reasonable hill climb in the dirt from alomst a dead stop in 3rd gear. 1st gear us pretty much useless since it winds out so quickly. For example, riding on the street in a 45mph area, I am always in 5th gear if I don't want the bike to be winding out. Just wondering if I should change the gearing, or if their was a special reason on this year bike they had the 50 tooth rear sprocket. Could the transmission be different than the other XR's? Thanks for any info.
