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
