I saw Stroud race the Britten at Daytona and Laguna Seca in 1994. It was an awesome piece of machinery that gobbled up other motorcycles like Pac-Man gobbling yellow dots...

You'd have to adapt a smaller diameter scooter wheel (maybe a 12~14 incher) to any motorcycle fork that you might find. The typical small motorcycle front wheel just wouldn't fit under the front "fender" of an NZeta... http://en.wikipedia.org/wiki/%C4%8Cezeta

Nothing on the NZ market that I can afford suits - anyway, I have fond memories of the scooter ... I live rurally beside State Highway 1 so _anything_ I buy has to do 60mph inside 30 seconds or I'm toast. Sure, I can ride a 2 wheel bicycle or a scooter.

Machining up yokes is not a problem and gives me the chance to increase the trail. (curreently 75mm/3") Modifying other forks would make fitting a disk brake easy. Didn't think of Wikipaedia, must have a look!

Sadly he went and died of cancer before it was built. Seems to have reappeared on the Chch "jetpack" flying thingy, but I wasn't part of that. Did put a bit of thought into the V twin but there wasn't much more bhp to be had. Greg.P. |
