Norton Rotary Classic
1987 588cc air-cooled, twin chamber rotary, 79bhp, 227kg
What is it? A better attempt at the rotary theme than Suzuki’s RE5, but still odd in almost every respect.
Why so odd? The wankel engine had no connection to the earlier Norton name, but it kept the brand alive for a further decade or so. Oddest of all, this utilitarian roadster (check out the almost Eastern Bloc styling) formed the basis for Brain Crighton’s hugely successful Norton rotary racers.
Why you want one: Like the RE5, this is a bike with a massively enthusiastic cult following and those who run them, love them. Although thirsty, a rotary motor has a charm all of its own. Pricey though. Values: £6000-£10,000
