I see someone has dug up the sole non-road-going Spagthorpe again! Have we ever found the sole prototype?
The Spagthorpe Iguana broke both the naming convention and the road-bike convention that had been Spagthorpe for centuries. Lord Julian decided to try his hand at a different sort of racing venture, and commissioned his engineers to design a machine capable of the rigors of the Paris-Dakar race.
Sadly, the complexity of the final drive (though providing near-ideal packaging and suspension travel) caused many failures during the race. In frustration, the race rider shoved his motorcycle into an arroyo and walked off into the desert in disgust. The hollow wings caused the machine to float, and when the rains came to the desert, the sole Iguana was washed out to sea...
