The Aprilia RS50 Replica was a 49cc sports bike produced for the ‘learner legal’ market. The RS50 is powered by a single cylinder, aluminium cylinder block, liquid cooled, 2 stroke engine (made by Motori-Minarelli and known as the AM6 engine). Later models (2006 onwards) were fitted with an engine manufactured by Derbi.
The bike was a smaller engined version of the RS125 and RS250 with similar bodywork styling. The RS50 (in stock form) was restricted to 30mph to comply with UK and European learner rider restrictions but could reach speeds of around 65mph in derestricted form.

Other stuff…..
The Aprilia RS50 Replica was a 50cc, 2 stroke learner sports bike manufactured and sold in the UK between 1999 and 2004.
The RS50’s styling was based on the popular Aprilia RS250 and featured a diecast aluminium frame, 280mm stainless steel front brake disc and 17 inch front and rear wheels.
Aprilia improved the handling from previous models with a larger front wheel (17 inch instead of 16 inch) and by lightening the front end of the RS 50 Replica.
Although the RS50 was usually restricted in the UK to 30mph, unrestricted versions of this bike (mainly imports from countries that didn’t have restrictions) were capable of around 60mph.
Buying advice…..
Although the RS50 is a good and popular learner legal sports bike, this does unfortunately, have a downside 🙁
These bikes are very often owned by younger riders who don’t have the money, knowledge or experience to properly maintain them so there are numerous RS50’s out there with botched repairs and piss poor ‘performance modifications’ that any buyer should be wary of.
A general sign is how the bike looks, if it’s scruffy and dirty with panels missing, nearly bald tyres and a drive chain dragging on the floor it will probably need alot of work doing to it….
The other downside to the RS50 is that they don’t wear well, especially in the UK weather.
When the RS was designed and manufactured, Aprilia tried to keep the weight as low as possible (in keeping with the RS’s racing origins) which meant they used lighter and smaller bits in certain areas of the bike. It’s not uncommon for the wheel bearings on higher mileage (30k plus) bikes to fall out due to the wheels being worn out so higher mileage Aprilia RS50’s are best avoided.
As with all Italian performance bikes, make sure the owner has used good quality 2T and gear oils as they don’t like being run on poor quality (i.e. not fully synthetic) oils.
Another thing to consider when your buying these bikes is that this ISN’T a scooter and doesn’t have a scooters running costs! Bear in mind that the Aprilia RS 50 uses motorcycle tyres (instead of cheap scooter tyres), fully synthetic oils and generally more expensive parts! So the RS50 isn’t always ideal for someone on a budget…..

i agree with all your comments on young riders and them using them as work horses,but why not give the ones that do look after them a mention,and yes i know they are only a few but if you teach them right from the start they do look after ther bike whatever it is they ride
Yep, that’s a fair point.
Good and well looked after RS50’s hold their money and are quite desirable amongst people who know what they are looking for.
I love these bikes, had one when I was 16, bought it broken, bad wheel bearings, chain rusted off, seized rear brake, electrical problems and a seized engine! bike came with a 2nd engine which I replaced the cylinder and piston anyway, new sprockets and chain, rebuilt the rear brake and piston cylinder, did some rewiring and replaced that little green block thing cant remember what its called haha, replaced all wheel bearings.
was a great little bike they look great and ride great, unfortunately the old girl met her end with the front of a landrover that didn’t look on a marked crossroads! was a custom purple metal flake paint job too!
but yeah it is true that they require more expensive parts (and I fully agree about the fully synthetic oils! I put Tesco oil in once and it made a smoke screen behind me and bogged the engine down so bad) always go premium with the oil!
