Here is a nice option for our Z125s. I picked up a 28t to hopefully get me some better top end at lower rpm. Two teeth down as opposed to the 3 or 4 when going up or down on the front. Hopefully the hindle, pcv and cam will provide the power to pull the gearing.

We can make just about any size you want from 26t up(may be possible to go to 24 or 25, depending on clearances), in aerospace grade American milled 7075 aluminum, 100% handmade in the USA, can anodize in several colors, tightest tolerances for the least slop and wiggle, and we've probably got the price beat for the quality of our products. We can do extra light and custom design CNC cuts. The standard lightening hole pattern makes the sprocket weigh just under 1 pound. Up to 39t for under $50. Next time you want to change, give us a call. 931-788-1617
