Electrical Walkaround:
Cold Start Video:
American fans of Aprilia rejoiced when the Italian firm announced that they would export the RS125 to the US, though it wasn’t all good news – due to EPA emissions standards, the baby RS was exclusively for closed-course riding even though it came with lights, mirrors, a horn, and everything else you’d expect to see on a street-legal machine. The 125cc 2-stroke engine is a Rotax unit, and fueling was handled by a 28mm Dell’orto carb. Dry weight was just 280 pounds and while it seems like a tiny bike, the ergonomics aren’t bad for bigger riders, either.

MCN called it the “undisputed icon of the 125cc class“, adding that its “incredible handling beggars belief.” For more information on what this pocket rocket feels like to ride, check out this review from Motorcycle News.

This example is VIN: ZD4PYA0046S000906. The seller acquired it from a private party in December 2024 through an Iconic Motorbikes auction.

During his ownership, the seller has covered 106 miles. The odometer shows 914 miles.

Per the previous owner:
“I became obsessed with owning a two-stroke road bike. My options were an RZ from the 80s or one of these (in my price range). I found this one in LA, drove out and picked it up, brought it home as a running but restricted RS125. It had been imported from Europe and still displayed kilometers on the odometer. I slowly completed the modifications and enjoyed it for a short time before life changed and I no longer had the time to spend with motorcycles. You could not get this bike street legal from the factory in the US, so the livery along with being equipped from the factory with turn signals etc make this bike truly one of a kind in the US.”
Maintenance:
“New air filter and spark plug. Battery is one month old.” The seller states that there are no known mechanical issues.
Modifications:
34mm Dell’Orto carb and power valve for de-restriction.

It is riding on Michelin Pilot Street tires with date codes of 4416 and 4516.


The sale includes 1 ignition key.

Cosmetic Blemishes: please see the album in the “Photos” tab for all known cosmetic blemishes. Here is a selection:
“Cosmetic issues on the bike from the previous auction has been addressed. Minor scratch on the fairing stickers.”


Currently located in Newport Beach, California, this Aprilia is offered on a clean California title with registration that expired in January 2026.

Per the California DMV website, it would cost $425 to make registration current through January 2028, although it should be noted that this would include the registration fee for 2026, if the bike is registered in or after January 2027, the cost would be about half this amount.
