Refine Acceleration with Yokomo B11-OP1A Aluminium Upgrades

The Yokomo B11-OP1A Option Parts Set swaps heavier steel drive cups for machined aluminium versions, cutting rotating mass and improving throttle response. The kit also includes lightweight aluminium shock end balls to promote smoother damper action, which helps with consistent setup in stock classes.

Chassis Compatibility Details

These components are compatible with a range of Yokomo frames including MRTC-BD11-1, MSR-BD11, MRTC-BD11A-1, MRTC-BD11FA, MRTC-BD11US, MSR-010FE, and MSR-010FEA. Use them when you need reduced drivetrain inertia and crisper response for technical courses.

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.

Do aluminium drive cups affect gear mesh?

If fitted properly they should not. Verify pinion and spur engagement after installation and recheck under load to ensure the mesh remains correct.

Can I use the kit on a car for carpet racing?

Yes, reduced rotating mass benefits traction and response on low-friction surfaces like carpet, helping with quicker throttle transitions and precise corner exits.

Are spare parts available for the shock ends?

Shock end balls are a common replacement item; check parts listings for the B11-OP1A set and match ball size when ordering spares to keep damper geometry unchanged.
