This Year we have been working with Graham Sykes to develop his next steam rocket bike for his Force of Nature Project, We have designed and manufactured a new, larger pressure vessel, forming a core part of the new bike.
The new pressure vessel has been engineered with approximately 30% increased capacity, enabling the bike to carry more water and deliver a longer thrust duration of over three seconds. Alongside this, wider system upgrades are being introduced to increase the rocket motor’s performance, with expected gains from 32 ISP to around 40 ISP, significantly improving both power and sustained acceleration.
These enhancements are designed to support ambitious performance targets for the 2026 season, including:
- Exceeding 200 mph
- Sub-5.5 second quarter-mile runs
- An ultimate goal of achieving a 2-second standing ⅛-mile and a 4-second quarter-mile in the same run — a milestone never before achieved by a motorcycle
The new configuration is scheduled for testing in March, with competitive runs planned from April 2026.
2025 Achievements
Graham and the team delivered a series of outstanding results during 2025, further cementing the project’s position at the forefront of steam-powered performance. Key achievements included:
5-second quarter-mile passes, breaking into a performance bracket rarely seen in steam-powered vehicles
Multiple 0.7-second 60-foot launches, demonstrating exceptional initial acceleration
Consistent sub-2-second 330-foot times, highlighting repeatable and controlled performance
Successful competitive runs across major European venues, including Melbourne Raceway, Santa Pod, Hockenheim, and Straightliners
We are proud to continue working alongside the Force of Nature team as they push the boundaries of steam-powered propulsion, and we look forward to sharing further updates as the project progresses.
