Little Wonder – 2003 Aprilia RS50

Holding up Aprilia's presence in the beginner market, the Minarelli- engined RS50 was surprising robust, and ready for almost any speed mod.  With just break-in miles, this Cali-registered RS50 has thankfully seen none of that.

2003 Aprilia RS for sale on eBay

A scooter only to DMV, the Aprilia can make 65 mph out of its 49cc single, but uses motorcycle tires and wants a better synthetic oil to help keep its bearings alive.  The specs read like a bigger bike with cast perimeter frame, integral seat sub-frame, upside-down forks, and monoshock rear.  Cast wheels are 17 inch with 300 mm front and 180 mm rear disk brakes, and bodywork is a sweet RS250 lookalike.

Limited info but looks great and the owner says this in the eBay auction:

For sale is an awesome Aprilia RS50. This bike is street registered in California and runs well. This bike has never been down and has incredibly low mileage for the age. It is a real looker and gathers lots of attention.

A perfect holiday gift that will almost fit under the tree, this RS50 would take you across town or teach a featherweight a thing or two.  In a segment choked with knock-offs, here it the real deal, with classy RS colors.  And though there is a 50cc fun formula, it would be more fitting if it saw the racetrack from the pit lane...

  • I had a mint 01 back in 06 with just 850 miles on it when I got for only $1850! Adding a arrow pipe helped big time so does removing the restrictor plate from the reed block stuffer. Was way more fun when I put the 21mm carb and Malossi 80 kit.

    Buy it now price is insane for this bike regardless of the low miles I don’t think they where that much even new. You could buy a 250 or rz350 for that price.

    • Oh yeah and these version of rs50’s don’t have inverted forks. They were also legally sold in the states from 99 thru 05 fact it has a cali plate doesn’t mean anything special.

    • It’s also not a scooter it has larger than 12 inch wheels and goes over 30mph in my state it was a motorcycle required an endorsement to ride.

  • In California any 50cc 2 stroke is not a challenge with DMV

  • With many states since it’s not an automatic transmission and goes above 30 mph it’s not a scooter/moped.

  • I owned a Derbi GPR 50 for awhile that had the 75cc kit on it. I loved ripping it around. There’s something super fun about riding WOT everywhere…even if it is only at 35mph. I suppose these bikes might be falling into the same sort of thing the Dream 50 replicas are. They are kind of a novelty but if you want one and you’re only willing to buy low mile bikes you might have to through down some decent cash to own one.

  • They were $3000 new. I had a 2005 model which was leftover 2003 model dated 2004. Go figure. Anyway these were so fun to ride…but prepare to shift often… and did I say “often”. You feel like you are going 100mph as the little Italian Minarelli race engine (it is a race engine) sings it’s song. With a tail wind it will go 60. It’s a 7/8th’s size bike…some have upgraded forks (CBR 600 F-1’s fit perfect) with brakes. Always use synthetic oil. By the way I have a full set of new 70cc parts. frankderryberry@yahoo.com for list.
