I really want to like the idea of electric motorcycles, but I have very low confidence that they would be built for the long term. Having to worry about software and security makes me even less excited.

The first chemical though, Dichloromethane, found in some paint strippers is a highly restricted chemical in the UK.

It can be a silent killer in confined spaces.

It doesnt mention this though, I wonder if they knew.

SUBJECT: Firmware Release & Ongoing Security Measures

Dear Zero Owners,

March 25th Firmware Update (BMU V20)

On the morning of March 25th, as part of our ongoing improvements, we released a firmware update for select 2022+ Zero models that improves the accuracy of the battery state-of-charge and range display. This update addresses a condition where, over time, the system could overestimate available charge, which in rare cases could lead to the motorcycle shutting down before the display reaches 0%. Following installation, some riders may notice a lower battery percentage or reduced range estimate. This is expected and reflects corrected, more accurate readings — actual riding range is not affected.

See details at zeromotorcycles.com/firmware.

Ongoing Security Enhancements

Separately, we recently became aware of potential issues in our motorcycles’ firmware and are taking steps to address them with your safety and security in mind. This work is ongoing, and we remain committed to strengthening system protections across our platform.

We understand how important trust and dependability are when you ride. Thank you for your continued support.

Sincerely,

The Zero Motorcycles Team

In the section about possible attacks, it wasn't clear if those three options represented the worst things you could do or just possible ideas. It seemed to me that locking the throttle to maximum would be worse.
