Recently picked up 2003 CR125 with FMF SST and Shorty silencer. Currently has stock gearing 13/52. I ride almost 100% trail/woods with a lot of hills and tighter terrain. I know I will never get a lot of low end , and am fine with that, just wondering if anyone has had a similar setup and moved up to a 53t or 54t rear sprocket? I have searched and searched, and have seen the golden rule seems to be the 13/53, just wondering if I will feel the difference or if I should skip right to 54t for my riding. Any input appreciated.
