A bunch of people and places I've never heard of, but kind of neat nonetheless. Copied from the turbobike forum:
It's a 1978 S+S Silver Saxon built by S+S Performance in the UK as a limited run of 10. This is the totally unique No10, built especially for the heavy metal rock band Saxon, who owned it until 1981. It has never been registered as it was only used to ride on and off the stage as a prop by Saxon. The engine is a full Russ Collins job, running a ported Rajay blower. It's bored to 1105cc running at 8.9:1 CR, now breathing through a Mikuni HSR carb. It's just had a total engine rebuild.. wired liners, HD studs & nuts, all built by UK Pro-stock drag champion Dave Beck Racing.
The bike has only ever done a total of 1100 miles and hasn't turned a wheel in 26 years.
I once dreamed of owning all the factory turbos- even had both Hondas and the Seca. The only two left would've been the Suz xn85 and the Kaw z1rtc, which even though was a 3rd party conversion was factory approved. The more I rode & tinkered with the gpz's, the less interested I became in the others and eventually just didn't have time for them all. Storage also became an issue and she won't let me keep any in the house.
