chain sprocket engine Sprocket
We have several rear sprocket possibilities for our clients to “good tune” their gas operated bicycle to accomplish their desired optimal swiftness/power gear ratio.
A note to keep in mind: The larger the rear sprocket, the slower the bike will proceed, but will have capacity to climb hills. Small the rear sprocket, the quicker the bike will go, but will climb hills less successfully. You are trading power for rate or vice versa.
You can expect sizes of 36 tooth, 44 tooth, 48 tooth, and 56 tooth sprockets in the Large 9-hole gear. The inner diameter is definitely 1.4″, hole spacing is 1″. Discover table below for specs. Commonly, the large 9-hole sprocket with 48 tooth configuration should come with the 4G T-Belt Drive 4-stroke engine kit.

ENGINE SPROCKET, 13T
