APRILIA RS50  (2006-on)

Expect to see 55-60mph in sixth gear - impressive for an 8.4bhp, 50cc machine

Overall Rating 4 out of 5

If you can overlook the impracticalities, stomach the price tag, and keep it in top quality oil, the RS remains the bike of desire for 16-year-olds more than ever - and has the stunning looks to match. 

Ride Quality & Brakes 4 out of 5

The non-adjustable forks, simple cantilever rear shock, and budget Vee Rubber tyres are good enough to cope with some sporty knee-down action. The front radial brake caliper looks beefy but has been set up to be novice-friendly for clumsy and over-enthusiastic teens rather than to cope with constant track thrashing. On the road, the easy handling and ability to maintain momentum should easily make the RS rider the leader of the local moped gang. 

Engine 4 out of 5

No amount of throttle or clutch-slip will ever get the Aprilia off the line quickly. From then on up, however, it's a gas. Gather a bit of momentum and things get much better. Despite the single-figure power output, the light, well-spaced gearbox helps keep the tacho needle firmly at the top half of the rev counter. Expect to see 55-60mph in unrestricted form.

Build Quality & Reliability 3 out of 5

A lot of RS50s will have been ridden hard by 16-year-olds with little to no mechanical sympathy and filled with whatever oil was on offer at the local garage. If you can find an RS50 that's been looked after and run on good quality oil, it'll be much more reliable.

Insurance, running costs & value 2 out of 5

There's no doubting that £2,549 is a lot of money to pay for what is essentially a 50cc moped, but what price do you put on having the best bike a 16-year-old can legally own? And at least the 60mpg fuel consumption is hugely economical.

Equipment 4 out of 5

From a hundred yards away, the RS could easily pass for a 600. The scaled-down RSV1000R styling, upside-down forks, and OZ-style wheels create a convincing illusion of size.

RS50, best first bike!?

09 June 2015 by Peter Andre

Ride Quality & Brakes
3 out of 5
Rock hard seat, pillion is comfier, but the bike would not move 2 up! A teenager could last much longer on this bike, I usually have to rest every 30-45 minutes. The bike loves the twisties, and you just think your way around the bends.
4 out of 5
For its capacity, it has a good amount of power. No doubt is it the king of the 50cc's, but if mixed with a 70cc kit, exhaust and bigger carb, things really come to life! With the upgrades, it feels like a much larger bike, having no power below 7k or so, and then a violent power band to 12k, make sure you're up to the gear changes to keep it in this small range!
Build Quality & Reliability
3 out of 5
Typical 2 stroke engine, but look after it and it will be much more reliable. Warm it up well before riding, run it off good quality oil, and you should see a few thousand miles per rebuild! Corrosion and rust on exhaust, brake disks.
Value & Running Costs
3 out of 5
Could do with a new barrel and piston annually, although you could probably get away with just a piston and rings if the barrel is in good condition.
3 out of 5
Good dash, although it would benefit from a fuel gauge, being aimed at teenagers and all.
Buying experience

I bought privately, at £1100 for a 2009 plate.
