Finally found a 13t front sprocket
Going from the stock 15t down to the 14t made a noticeable difference in the performance of my 500. So, if a little is good then a lot must be better. I finally found a 13t and got it on today. And it is the one that will stay. Not surprisingly, the change in gearing has made my 500 a different animal entirely. The reduction in gearing is certainly not for everyone, but I came to the Rebel from having big bore dirt bikes forever. The Rebel's snappier throttle response is on par with some of the dirt bikes I have had. No more chugging when idling along in traffic, no more chugging if I short shift a gear, it will pull the front tire up when hitting second, and I don't keep checking if I'm in sixth.
It does wind more on the open road, but I rarely run much over 60, so no big deal. I had flirted with the idea of making some performance upgrades to the engine, but the gearing change has had enough of an impact, that I think that I will leave it alone. It really is that much snappier. All in all, for $20 or so, I couldn't be happier with the results. Maybe even better than I had hoped.
