Episode 1 of 400 MPH: The Last Run debuts on YouTube

A new six-part docuseries on the Top 1 Ack Attack’s push to break 400 mph has launched with Episode 1 on YouTube. The premiere revisits the garage-built origins of the motorcycle and the years of setbacks, rivalries and engineering that led to the current land-speed record.

Why it matters: - The series tracks one of motorsport’s most extreme engineering efforts: a bid to make the first motorcycle break 400 mph. - The Ack Attack still holds the motorcycle land speed record at 376.363 mph, set in September 2010. - The story shows how a record program can depend on engineering, funding, weather windows and rider risk, not just horsepower.

What happened: - Episode 1 of 400 MPH: The Last Run is now available on YouTube. - The six-part docuseries follows the Top 1 Ack Attack team as it prepares for a final attempt to break 400 mph. - The premiere retraces the motorcycle’s origins and the early work by engineers, fabricators and volunteers who built the streamliner. - The episode is narrated by Tory Belleci, known for MythBusters, White Rabbit Project and model-making work at Industrial Light & Magic. - New episodes are set to be released October 8, 2026 on YouTube.

The details: - Mike Akatiff conceived the Top 1 Ack Attack through Ack Technologies, the company that gave the machine its name. - Top 1 Oil backed the project and helped fund the streamliner. - The motorcycle uses two turbocharged Suzuki Hayabusa engines. - Rocky Robinson rode the machine inside the streamliner. - Episode 1 shows early prototypes, hand-built components and testing at the Bonneville Salt Flats. - The team faced crosswinds, traction loss, mechanical failures and changing salt conditions. - Some runs ended with crashes and broken parts. - The Ack Attack first claimed the record in 2006. - Competing streamliner teams traded the record with the Ack Attack before Robinson reached the current mark in September 2010. - The docuseries also focuses on the cost of chasing speed, including funding pressure, time away from family, physical danger and delays caused by poor salt conditions. - The company also included background on ACK Avionics, which began in 1972 as ACK Products Inc. and later expanded into aviation equipment. - ACK Avionics says it is headquartered in Santa Clara, California, and designs FAA TSO-certified emergency locator transmitters and altitude encoders. - The company says its products also have approvals from EASA, Transport Canada, Brazil’s ANAC and Japan’s JCAB. - ACK Avionics says it has produced more than 280,000 units with no airworthiness directives or safety recalls. - Top 1 Oil says it is a family-owned lubricant company founded in 1979 and based in California’s Silicon Valley. - Top 1 Oil says it sells products in more than 60 countries and has won the President’s “E” Award for export excellence. - Top 1 Oil also says it powered the Ack Attack to the 376.363 mph motorcycle land speed record. - The source includes a media kit for the Top 1 Ack Attack 2026 Bolivia Speed Trials and a link to more information: Social media media kit.

Between the lines: - The project’s appeal is as much about persistence as speed. - The documentary frames the record chase as a long technical campaign, with each failed run feeding the next attempt. - Belleci’s role signals a push to make technical land-speed racing understandable to a broader audience.

What’s next: - The remaining episodes will follow the team’s final push toward a 400 mph attempt. - Viewers can expect more focus on preparation, testing and the risks of record chasing on the salt. - The current record remains 376.363 mph until the team or a rival surpasses it.
