Cut Rotating Mass with Yokomo B11-OP1A Aluminum Components

The Yokomo B11-OP1A Option Parts Set upgrades standard steel parts to aluminum drive cups at both front and rear, lowering rotational weight to deliver quicker throttle response. The included light aluminum shock end balls aid freer damper movement, useful for stock-spec tuning and consistent responses lap after lap.

Which Chassis Work with This Kit

This kit fits multiple Yokomo chassis models such as MRTC-BD11-1, MSR-BD11, MRTC-BD11A-1, MRTC-BD11FA, MRTC-BD11US, MSR-010FE, and MSR-010FEA. These parts are aimed at pilots who want noticeable drivetrain responsiveness without altering core geometry.

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 aluminum drive cups improve acceleration?

Yes, by lowering rotating mass the drivetrain can accelerate more quickly, which produces a sharper throttle response especially noticeable when exiting corners.

Do these parts require different maintenance?

Routine checks of spline fit and bearings remain important. Aluminum parts should be inspected for play and cleaned to avoid grit accelerating wear on mating steel components.

Can I pair these with ball-race shock ends?

Yes, many tuners swap to ball-race or adjustable shock ends for extra precision. The B11-OP1A shock end balls are a lightweight baseline that pair well with other upgraded links.

Will this affect handling balance?

Reducing mass at the wheels can change transient response but it does not alter suspension geometry. Expect crisper acceleration and slightly quicker turn-in without major balance shifts.
