You demand the best, so does Rotor Ron! This is one of the best 25.5 motors I offer.

“The Full Monty” is British slang for “the works”. In other words, this motor has every option available on it. By using aluminum screws and timing ring, I am eliminating magnetic drag and interference that is caused by normal magnetic metals. Then I take it a step further and install ceramic bearings lubricated with SHAG Oil and use Teflon shimming for even less drag. All these upgrades help unleash each motor’s true potential. The result is around an average of 300 more rpm on the dyno (under load) and improved efficiency. Also saves about 2g of weight. This is for a racer wanting the best possible edge.

This motor is professionally built and tuned to Rotor Ron’s strict parameters. What does that mean you ask? It includes the rotor properly shimmed, complete evaluation of stator poles, rotor strength & asymmetry and sensor board deviation. This motor has an aligned sensor board that is within my personal strict standards. Bottom line, you will get an awesome motor!

Includes Rotor Ron Dyno Service and instructions that will get you up to speed, fast! (A $34.99 Value!)  No need to ever touch the timing again! Motor specs and dyno sheet included along with stickers for your vehicle. Sensor wire sold separately (I have 4 different lengths to choose from on the website)


The Technology:
-Proprietary R1 Stator Laminate Material
-R1 V21 Stators are designed using computer simulation technology
-Epoxy bonded end wind
-Ultra low resistance collector ring
-All of above results in lower resistance compared to V16
-Improved punch and top end
-Aluminum timing ring included

The Application:
Perfect for any 25.5 class.





If you are unsure this is right for you, please reach out to me first before purchasing.

Rotor Ron always recommends SHAG Oil to keep your bearings running smooth.

*R1 Motors do not come with sensor wires, I have 3 sizes to choose from in the “Add On” section.
