well yes i agree, but the issue i have is with bikes that are competing in a classic class that are built to a spec that wasnt available in the period they represent. on one level of racing folks ar blatting round tracks on 1980's superbikes where thee regs say that they cant have more modern brakes and suspension because its not authentic to the era, and then you have 500cc+ 'manx' nortons running 4 valve heads and nikasil liners, modern electronic ignition, superlight slipper pistons and titanium valves and retainers, that rev to over 10 thousand rpm and make over 70bhp, thy externally resemble manx's of the period, but their new crankcases are built to modern spec with extra bracing, theyve got better cooling, the exhaust ports and inlets are at different angles and sizes to the ones they purport to be, lob in close ratio boxes with 6 or 7 gears, etc etc. now dont get me wrong, im not a luddite, the technology that has allowed these bikes to be built is incredible and im in some awe of it, but lets have some perspective if theyre going to be put out against authentic period bikes.
