The Y2K is in fact built around a C18, not a C20 (so there's an even greater chance of losing your wedding tackle when the disks rupture...!). Ted's machine is beautifully finished, and he’s developed a neat proprietary starting system for it, but physically it's pretty damn large for those of use more used to riding today's generation of crotch rockets. A Gixer or R1 will beat the Y2K off the line, but once it spools up (~60mph), it’s unstoppable. Thankfully, there's an integrated RWR !!
In addition to the Y2K, there have been a handful of amateur turbine bike projects, including
Emile van Essen's GTP550, based on a Garrett GTP30, and John Wallis’
Garrett TV84-powered bike in NSW.
