Just leaving this here in case someone else runs into the same issue and needs a solution.
I ordered a bike directly from Stark in December 2024, and once I received it, I started having throttle issues. After just a few minutes of riding, the throttle would cut out, a solid red light would appear, and I couldn’t switch into any power modes—it was stuck in neutral. If I let the bike sit for a few minutes, it would start up again like normal, but the problem would return.
I reached out to Stark for help, but we weren’t able to find a solution. I turned to the forums and found a temporary fix by disconnecting and reconnecting the battery to the VCU. After that, the bike ran fine for long rides without issues.
However, when I updated the firmware from 1.0.159 to 1.0.218, the problem came back—this time with a new warning that the inverter was overheating. Oddly enough, when I checked, the inverter wasn’t even warm to the touch.
I contacted Stark again, explaining the issue and suggesting there might be a problem with the inverter or VCU. They got back to me within a day, checked my bike’s data, and confirmed that the powertrain needed to be replaced due to a faulty temperature sensor in the inverter. Here’s the response I received from them:
Thank you for contacting Stark. we are looking at the data of VIN XXXX and the powertrain needs to be replaced as the inverter has a faulty temperature sensor on it.
There are two alternatives on how to proceed. One is to send the powertrain directly to you for you to replace it. Here are some guidelines on how to do it: How to remove and install powertrain unit
The other alternative is for you to drop your bike into one of our dealers for them to replace it. Stark Future Dealers | Stark Future
Please let us know your decision and if there’s anything else we can assist you with.
Best regards,

Really impressed with there tech service this time around and how they were able to look up my bike data to determine that a new powertrain was needed. I decided to have the powertrain shipped to me so I could do the swap myself. This morning, Stark reached out again to confirm that my order has been placed and provided my order number. Now, I’m waiting for it to arrive and will update once I go through the process of replacing the powertrain.
Hope this helps anyone dealing with a similar issue!
