Most people fail to put the Britten's performance in it's proper context.
They tend to compare the bike with today's performance levels.
Back in the 90's when the Britten was created, it was putting around 180 HP at 12,500 RPM.
That was amazing back then. And the fact that it was an engine created in a backyard shop makes it even more amazing.
When it was racing at Daytona, it was against the factory Ducati 888's and was wheeling past then at will.
When the rider pulled in, he told John he was only using 3/4 throttle, and that's after welding a cracked cylinder in a cycle shop the night before.
I've seen The Worlds Fastest Indian (about Burt Munro), which was a really good movie, but I think the Britten story would warrant a movie of it's own.
The man and the machine never cease to amaze me.
