      Custom cut thumpstar sprocket.

      Wish it was available in steel. Not sure how durable the aluminum will be. But it does what it's supposed to went to a 17t front and 39 rear. (15/43 was stock) On my thumpstar 212 .Really gave it the top end speed it needed. *** Thank you. We use the same sprocket material on our custom race hillclimbs dirt bikes too ***
