RTR Revolver Alpha Motor & 420 Chain Conversion Kit

The RTR Revolver Alpha Motor & 420 Chain Conversion Kit is listed with two rear-wheel-size options. Selecting the correct version matters because the source specifies a different rear sprocket for each wheel size.

Supplier specifications

• 12-inch rear-wheel option: 8-tooth front and 55-tooth rear gearing
• 14-inch rear-wheel option: 8-tooth front and 63-tooth rear gearing
• Conversion identified by the supplier as a Revolver Alpha motor and 420-chain kit

Confirm the bike model, rear-wheel size and complete kit contents before choosing a version. The supplied record does not establish fitment across all RTR models.
