I dont know much about them either really. I hear its a work around to programming Yes. MM = MagicMagnet The MM is not a workaround to reprogramming the controller. It will not make your GEM perform better. The only thing it will do is interrupt the motor rpm pulses so that the controller thinks you are going slower than you actually are. It will allow you to side step the maximum speed limit in the controller. That’s it. With a programmer, you can tweak things like the motor field parameters, regen, and raise the speed limit on some controllers etc. The motor parameters can actually get you more speed. Some controllers require both the MM and a programmer as the max speed is hardcoded. The T1 and T2 (used from 00-04), however, do not as they have an editable parameter called “Max overspeed” this is the speed governor, so the MM is not needed for them. ---

I just contacted D&D. Apparently they state they do not have any motor that will go or is rated over 25mph. I asked if the one that Ride 4 Fun sells is theirs, but they did not confirm. They stated if i wanted to go over 25 then i should contact them. So now i am confused. Is D&D not wanting to state their motors can go over 25 for liability reasons. But then why is R4F saying their motors have been upgraded and engineered for higher speeds and heat? Something is not making sense… ---

I service all GEM motors. contact me by Email, [rodneyadiehl@aol.com](mailto:rodneyadiehl@aol.com) We as, user of motors, exceed the manufactures 25MPH specifications. My cart does 40 MPH If the motor burns up it’s my problem. there is no warranty. ---

> [@jonbbrew](#): > > I just contacted D&D. Apparently they state they do not have any motor that will go or is rated over 25mph. their motors are rated for a certain power output and RPM so MPH has nothing to do with them. If you put enough gears behind the 5HP motor, streamline the crap out of the body and get onto the salt flats you can probably hit 100MPH and not exceed 5000 RPM. Now if you want to push this motor beyond its spec’s and for short bursts you likely can get away with it and still have a functioning motor on the way back down the hill. And what a vendor says to sell their product might or might not be connected to reality. ---

D&d got sued because a guy got killed in his golf cat that had been modified to go faster. They will not recommend anyone to go over 25mph. ---

I’d take that motor, if still available. If you can reprogram a T2 controller as well, I’m interested. ---

"It is available and I can reprogram your controller. Leaving for Europe Thursday so not enough time to get your controller to me and done. I can ship motor before I leave and do controller when I get back if that works. ---

Have an R4F blue motor in our 2001 and there’s some added pieces on upper shock mount (2 flat pieces of 1/4” aluminum plate) that push the shock out about an inch. Easy to fabricate, happy to send an image if of interest. ---

> [@Nato](#): > > Will the R4F 7.5 not fit? I’m thinking it might depend on the year the blue motor was built, or different model GEMs from the 00-04 range have different clearances. No shock tower mods needed on my 02 longback (truck model - eventually renamed the eL series) for a blue motor. plenty of cleararance. ---
