Honda only offers the front and rear sprockets in one size each - 18 tooth front, 40 tooth rear. SunStar offers several options: 16, 17, and 18 tooth front, and 39, 41, 43, and 45 tooth for the rear. So you have several options if you want a little quicker acceleration. You can go smaller on the front sprocket, or larger on the rear sprocket. I don't know if you can change your sprocket size on this bike without affecting the length of the chain or not, but going one tooth shouldn't be a problem. There may be other options (vendors) out there for non-standard size sprockets. I am sure other members will respond who have actually installed non-standard size sprockets on their bikes.
