When the Sur-Ron 60V “Mild Bee” electrical dust bike got here out in January of 2018, it was an instantaneous hit with excessive gross sales as a result of it was way more reasonably priced in comparison with the Alta and the Zero off-road bikes. Then, a brand new competitor confirmed up a short while later, the 60V MX-4 Talaria Sting (to see that article from April 2023, click on right here). I wrote about the advantages of the Talaria Sting which was primarily an improved trendy “IPM” model of motor that would deal with future efficiency upgrades, in comparison with the old-style SPM.
Electrical hot-rodders have usually taken considered one of two routes to enhancing efficiency, for riders who need that “little one thing further”. You possibly can swap-out the controller to enhance the amps, which helps acceleration. Nevertheless although this was the most cost effective method to get more durable acceleration, extra amps equals extra warmth, which leads us to the second means to enhance efficiency…
Bumping up the volts from 60V to 72V.
Doing this raises the facility with no important enhance in warmth. These motors can take fairly a bit of warmth, however the controllers and batteries might be delicate to warmth, if you happen to wish to run steep uphills for lengthy distances, with no cooling-off interval the place you re merely cruising alongside.
The one concern with upgrading to 72V is the price of swapping-out the controller and in addition the battery. Sufficient present riders may wish to have a spare 60V Sur-Ron or Talaria battery pack, that you need to have the ability to promote the inventory unit to defray among the swap-costs. Nevertheless, if you understand you already wish to have the final word electrical dust bike, essentially the most cost-effective possibility is to purchase a manufacturing unit 72V Talaria.
The inventory Talaria MX5 comes with a 48-Tooth rear sprocket, however one of the crucial fashionable upgrades for Sur-Rons and Talaria’s is to get a bigger rear sprocket. For those who swap to a sprocket with 10% extra enamel, it is going to decrease the top-speed 10% and it’ll bump-up the rear wheel torque 10% for improved hill-climbing.

Right here is Karls article on what you’ll be able to count on when swapping to a bigger rear sprocket.
From Greg M…
“…I’ve about 100 miles on the brand new MX-5. It simply does the whole lot very effectively. Off-road, it’s a pleasure to tear the paths with. I’ve performed on the streets some, and it has extra energy than you want proper out of the field. Vary appears according to most different bikes on this class, however will take the ever so barely much less run time for the trades in strong construct, braking, and energy output.
I swapped out the inventory tires for the Tusk Floor’s, added a direct-mount stem/lock, Luna bars, a couple of little customized gadgets. The value level is wonderful for what you get. It will value you many thousand {dollars} in upgrades on the sooner platforms to succeed in the out-of-box efficiency you get with the MX-5…”
