Tune the RB7/RB7SS Balance with Kyosho UMW751

The Kyosho UMW751 - 32g Battery Weight for RB7/RB7SS is a compact, purpose-made weight that fits beneath the battery to adjust the car's center of gravity. Placing it correctly helps stabilise the chassis for smoother control at speed without sacrificing responsiveness.

Benefits on Track

This 32g weight is calibrated to add just enough mass to improve traction and reduce body roll while keeping the car nimble. Drivers aiming for consistent lap times will notice firmer cornering and better mid-corner grip on tight circuits.

Quick Fit Guide

Fitting the Kyosho UMW751 is simple: slide it under the battery tray in your RB7 or RB7SS and secure it so it cannot shift during running. Verify clearance and seating before your first run to ensure safe operation and repeatable handling changes.
Remark :
Due to limited stock availability, please notice that some Kyosho 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 this weight fit other Kyosho cars?

The UMW751 is made for the Ultima RB7 and RB7SS mounting layout. It may fit other models, but form and performance gains are optimised for those two chassis.

How noticeably does 32g change handling?

Thirty two grams shifts the balance enough to tighten corner entry and reduce roll, especially on grip-limited surfaces. Expect subtler but useful changes rather than drastic handling overhauls.

Any tips to keep the weight secure?

Use double-sided tape or the factory battery straps to hold the weight in place. Check it between sessions and after hard impacts to avoid movement that could affect handling.
