The Sammy Miller Motorcycle Museum in New Milton, England, holds more than 500 motorcycles, almost all in working order. Its workshop team continues restoring machines, while selected museum events let visitors hear historic engines running.
The Miller trials prototype offers one example. Miller developed it in 1978 with Andrea Mosconi at Hiro, using a Hiro engine. Series production never followed. After years in storage, the motorcycle was restored; in 2022 the museum announced that it was on display.
This kind of collection invites a view of restoration beyond glossy paint. A working mechanism prompts different questions: how was it adjusted, what did it sound like, and what skills did it demand of its rider?
