Hearing it for the genius of Chris Whitworth, twostroke leakdown tests, and background noise
Chris Whitworth’s Yamada may not be the best-looking special ever to appear in PS – but it’s certainly the most ingenious – and one of the cheapest too. The man really does know what he’s doing. Using ERW (electrical resistance welded) tube instead of expensive CDS (cold drawn seamless) is the sensible way to go with a simple
trellis, and his front-mounted oil tank idea is so simple and so effective – a temperature drop of 10-degrees is significant – without an oil cooler!
So, it took 2000 hours to build, he says: by my maths that’s only 83 days, or just under three months, way less than most of us take to restore a bike, never mind virtually build one from scratch. He’s also got ramair, centralised mass, and many of the holy grails of modern motorcycle manufacture incorporated into the Yamada – and all starting in 1995.
What other tricks has he got up his sleeve? When’s he going to build another special with all the engineering solutions of the next 20 years already built in? I think we should be told. Roger Nixon, email
