1930 Norton 490 CS 1

1930 Norton 490 CS 1 sits among the sporting half-liter machines that defined Norton's reputation before the CS1 name gave way to the later International models. This was a genuine overhead-camshaft sports machine built for riders who wanted real pace on open roads, not just a commuter with a badge. The chain-driven cam gear and the engine's willingness to rev made it a bike you worked with on a fast run rather than simply pointed and rode, rewarding a rider who understood how to manage a period gearbox and brakes while still asking the motor for everything it had. A top speed approaching 130 km/h was genuinely quick for 1930, putting it ahead of most rivals on the road. The 1930 model carried over without significant mechanical changes from the prior year, so buyers comparing it to a 1929 example should focus on mileage, service history, and condition rather than spec differences. Today this bike draws serious prewar collectors and vintage racing enthusiasts rather than casual restorers, people stepping up from smaller British singles who want a documented, well-sorted example with matching numbers and genuine ownership history behind it.
