The Yamaha Aerox is a funky 50cc race replica two-stroke scooter. It's nippy, agile and lots of fun, although the single seat limits pillion options.

It’s one of the best looking scooters around and can be seen tearing up city streets as well as being paddock transport for Yamaha-sponsored MotoGP/WSB and BSB stars. Upside forks and disc brakes means the little Aerox R can be knee-scrapingly good.

Yamaha Aerox 50cc Rossi Replica

The Aerox became famous in the UK thanks to the vast swathes of Rossi Replica bikes on the market. First launched in 2007 and updated in 2010 (pictured below), this stickered-up twist-and-go was the closest many 16 year olds would come to swinging a leg over Vale's MotoGP machine.

The Aerox is very light and nimble, so perfect for nipping around town. With its upside forks, fat 13” tyres and discs brakes, the Yamaha handles far better than the average shopping scooter.

Making a claimed 2.6bhp, the Aerox R is powered by a liquid-cooled, single-cylinder, carburetted two-stroke motor. It has an electric start and a CVT gearbox. In restricted from it’ll only do 30mph, but there are derestriction kits available to unleash more power.

Sports scooters like these are going to be used and abused by their 16-year old owners, or wheelied around paddock by racers, so they need to be durable. The Aerox R ticks that box and is well finished.

We've only got one Yamaha Aerox 50cc owner's review on the site, and with five stars across the board it's clear our commenter is happy with his purchase.

As cool as the Aerox R is, three grand was a lot for a moped, especially when it doesn’t offer any performance gain over the competition. Save your money for a 125 and buy a cheap moped when you’re 16.

However, if you're after a seriously cool-looking 50cc bike as a used purchase, you could do a whole lot worse than the Aerox. Yamaha are known for building strong bikes that last a long time, and this is no exception.

It’s pretty basic, but you do get sporty bodywork and racy graphics, a supersports-style filler cap, discs brakes and upside down forks.

Don't expect massive levels of standard kit, but there have been plenty of race replica versions on sale over the years to impress your mates down the pub. See the full list below.
