Precision Performance for Competitive Racing

The Yokomo RPM-M4215A focuses on predictable power delivery and race-ready behaviour. It is engineered to help drivers extract consistent lap times through careful tuning and setup work.

Designed for Controlled Power Delivery

This motor's output profile has been refined to give accurate throttle response and stable torque. Those traits make it easier to balance the car and manage exits from slower corners.

Consistent Operation under Pressure

High attention to construction and component alignment helps the RPM-M4215A remain stable during repeated runs. Consistent operation reduces setup surprises and aids in making reliable race-day adjustments.

Practical Advice for Setups and Maintenance

Select an ESC that matches the motor's current demands and allows timing changes. Regular checks of bearings, mounts and electrical contacts will keep performance repeatable throughout a season.

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.

What are the first setup steps for a new motor?

Begin with standard gearing and conservative ESC timing, then run short sessions to observe temperature and throttle feel before making incremental changes.

Can this motor be used in touring car classes?

Yes, it is suited to competition classes where a 21.5T specification is permitted, provided you follow class rules on tuning and electronics.

How do I check for wear without dismantling the motor?

Listen for unusual noises, check shaft play, and monitor lap time consistency. If performance drifts, then inspect bearings and connections more closely.

What should I consider when switching tracks?

Adjust timing and gearing to suit grip level and layout length. Lower timing and shorter gearing help on low-grip or technical circuits, while more timing benefits higher grip, flowing tracks.
