About the MR-04


Advanced MR-04 Chassis for Improved Handling

The MR-04 chassis introduces multiple upgrades over its MR-03 predecessor, including a lower center of gravity and improved steering geometry. These enhancements provide sharper, more predictable handling and better cornering stability, essential for on-road racing. The W-MM (wide, mid-motor) configuration also gives users greater tuning potential, making it easier to optimize performance for different track layouts.

Ready for Customization

Ideal for drivers who want to create a one-of-a-kind Mini-Z, this set is fully compatible with Kyosho’s extensive range of Auto Scale Collection bodies and unpainted white kits. You can paint your body to match a real car or your own racing colors. This level of customization makes it perfect for both casual racers and competitive drivers who demand a personalized RC experience.

Reliable KT-531P Transmitter and Balanced Motor Power

Included in the set is the KT-531P pistol-grip transmitter, a user-friendly and reliable controller that makes the Mini-Z feel like a full-sized race car. The 130-class MZ9PB motor delivers balanced power suitable for both beginners and experienced racers.

Works great!
Style: with Pre-Filter
I bought this set to put on my original euphy robot vacuum. It works perfect! All pieces fit perfectly and were so easy to change out. I’ve had the new parts installed for a few weeks and it works so much better now. I recommend them for sure if you need any new parts for yours!

Very good Value for replacement part and reliable
Style: with Pre-Filter
Very good product for the price - the front brushes wear fast compared to the original Eufy’s but for the value you do get a lot of product. So only 4 stars but just for the brushes “appearing to not last as long and bend but the buy is worth the extras. The filters look and work identical to the OEM. Good stuff - thanks!
