When the Sur-Ron 60V “Light Bee” electric dirt bike came out in January of 2018, it was an instant hit with high sales because it was much more affordable compared to the Alta and the Zero off-road motorcycles. Then, a new competitor showed up a short time later, the 60V MX-4 Talaria Sting (to see that article from April 2023, click here). I wrote about the benefits of the Talaria Sting which was mainly an improved modern “IPM” style of motor that could handle future performance upgrades, compared to the old-style SPM.
Electric hot-rodders have typically taken one of two routes to improving performance, for riders who want that “little something extra”. You can swap-out the controller to improve the amps, which helps acceleration. However even though this was the cheapest way to get harder acceleration, more amps equals more heat, which leads us to the second way to improve performance…
Bumping up the volts from 60V to 72V.
Doing this raises the power without a significant increase in heat. These motors can take quite a bit of heat, but the controllers and batteries can be sensitive to heat, if you like to run steep uphills for long distances, with no cooling-off period where you re simply cruising along.
The only issue with upgrading to 72V is the cost of swapping-out the controller and also the battery. Enough existing riders might like to have a spare 60V Sur-Ron or Talaria battery pack, that you should be able to sell the stock unit to defray some of the swap-costs. However, if you know you already want to have the ultimate electric dirt bike, the most cost-effective option is to buy a factory 72V Talaria.
