MaxTorque 3/4" Drum & Sprocket

• These drum and sprocket sets are to replace the existing 10 tooth drum and sprocket with your choice below.

• If you want a little more speed for your 120, you can change the existing 10 tooth drum to a larger sprocket to increase top speed..  Each tooth change on the clutch increases the speed by approximately 2 to 3 mph.

• If you are disabling the governor you should strongly consider increasing the sprocket size.  If not, you may over-rev the engine.  A larger sprocket will cause the engine to work a little harder and keep the rpm down.

• Note: Although we work very hard to keep our prices low, MaxTorque has revised their pricing schedule and therefore we have been forced to make some pricing changes.  Although we have absorbed some of the cost, the prices still needed to be raised slightly.

• Note: MaxTorque discontinued the 11 and 12 tooth #420 sprockets and has no plan to make anymore..
