Improve Throttle Control with Yokomo B11-OP1A Aluminium Parts

The Yokomo B11-OP1A Option Parts Set replaces heavier steel drive cups with machined aluminium units at the front and rear to reduce rotating weight and sharpen throttle response. The lightweight aluminium shock end balls support smoother damper action, which helps maintain consistent performance in stock class cars.

Compatible Yokomo Chassis List

The upgrade set is compatible with several Yokomo chassis models including MRTC-BD11-1, MSR-BD11, MRTC-BD11A-1, MRTC-BD11FA, MRTC-BD11US, MSR-010FE, and MSR-010FEA. These parts are useful for drivers seeking reduced drivetrain inertia and more immediate acceleration feedback.

Specifications

  • Material: Aluminum
  • Compatibility: MRTC-BD11 series, MSR-010FE series
Remark :
Due to limited stock availability, please notice that some Yokomo items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Will fitting aluminium cups void warranty?

Aftermarket upgrades can affect warranty terms depending on the distributor. Check warranty conditions before fitting, but mechanically the swap is a common and reversible modification.

What tools are needed for installation?

Basic hobby tools such as hex drivers, pliers and a small gear puller or pin punch are useful. A torque driver for hub hardware helps ensure consistent assembly without over tightening.

Do these parts suit both on-road and off-road use?

They are primarily aimed at on-road and race setups where reduced rotating mass and precise throttle control matter most, though they can be used off-road if geometry and durability meet your needs.
