Another Quick Tip on front sprockets
This tip brought to you from the forum... If you decide you need to change the gearing to fit your track, and the front sprocket is the way you want to go, you'll need a few pieces in addition to the gear. While these KAYO MR125 use TTR specs. on most things, the front sprocket is not one of them. Yes the spline shaft is the same, and it uses the same 428 chain, the gear retainer is not the same. When changing to a TTR spec. gear, you'll need the TTR spec. retainer and new bolts as well. If you look at the picture, I have the TTR retainer on the KAYO gear, and the KAYO retainer on the TTR gear. Bolts on the TTR are m5x10mm or maybe 12mm long.
