High-Precision Motor Mount for YZ-4S

The Yokomo S4-304 Motor Mount/Adapter is aimed at YZ-4S users who need a stronger motor attachment and flexible positioning. Made from aluminium, the part adds rigidity and keeps the motor stable under load. The sliding adapter enables straightforward motor alignment to achieve correct gear meshing.

Improved Stability and Heat Transfer

Matched to the YZ-4S chassis, this mount helps stabilise the drivetrain and the aluminium body assists in spreading heat away from the motor during prolonged runs. That supports reliability when you are running multiple heats or long practice sessions.

Straightforward Installation on B-YZ4SF

Fitting the Yokomo S4-304 Motor Mount is simple for racers and hobbyists. It is compatible with the B-YZ4SF chassis for an accurate fit, making upgrades or replacements tidy and effective. If you are swapping motors or refreshing worn parts, this mount is a practical choice.
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 this fit the stock chassis without mods?

The S4-304 is designed to fit the YZ-4S and B-YZ4SF layouts. In most cases it installs without chassis modification, but confirm alignment during trial fit.

Are there recommended fasteners or torque settings?

Use the manufacturer recommended screws and tighten to hobby-standard torque values to avoid stripping. Check mounting screws after first few runs.

Does the mount affect centre of gravity?

Any aluminium part adds a small amount of weight, but the main benefit is a firmer motor hold. Overall balance change is typically minimal.
