For racers seeking predictable drivetrain behaviour on their Inferno MP9, the Kyosho IF410-47B 47T spur gear is a reliable choice. Constructed from sturdy steel, it handles repeated use across practice and race sessions.
The 47T option is aimed at riders who want subtle changes to final drive to match track layout or traction levels without major setup overhauls.
To correctly install this spur on an MP9 you will need the IF466 Center Diff & Servo Mount Spacer set so the spur meshes cleanly and the drivetrain runs without binding.
