Aprilia RS125 Overview
*Please note, this article will focus on the 2-stroke Aprilia RS125*
The Aprilia RS125 is a popular 2-stroke sports bike that packs a punch. It’s a great option for those who want to experience the thrill of a sporty ride without breaking the bank. The bike has a stylish look and is sure to turn heads as you ride it down the road. Although no longer available to buy new, RS125’s can still be picked up second hand fairly easily.
The engine of the RS125 is a liquid-cooled, 125cc, 2-stroke engine that can produce around 33 horsepower. The bike’s lightweight design allows it to accelerate quickly, and its agile handling makes it a joy to ride. Whether you’re cruising through the city or tearing up winding roads, the RS125 offers a thrilling ride.
The RS125 has an average fuel consumption of around 35-40 miles per gallon, not the best by today’s standards, but let’s face it, you don’t buy one of these things for fuel efficiency! It also has a relatively small fuel tank, holding just 14 litres, which means you may need to refuel more often than with larger bikes or mopeds. However, this is a small price to pay for the thrill of riding this sporty bike.
Overall, the Aprilia RS125 is a great option for those looking for a sporty ride on a budget. Its powerful 2-stroke engine, agile handling, and stylish design make it a fun and exciting ride. However, it’s important to note that 2-stroke engines require more maintenance than 4-stroke engines, so be prepared to take good care of your bike if you decide to go with the RS125.
Aprilia RS125 Top Speed
When it comes to the Aprilia RS 125, the top speed is heavily influenced by whether the bike is restricted or derestricted. A restricted RS 125 produces around 14bhp and can reach speeds of around 70mph.
In contrast, a fully derestricted RS 125 has a claimed output of 33bhp and can reach a realistic top speed of 90mph, however, with a few slight performance upgrades like an exhaust system, this little machine is perfectly capable of (just) breaking the 100mph barrier.
The analog speedos on the RS125 can be a little deceptive, and these are GPS verified speeds we are talking about.
Of course, whether you can legally ride a derestricted RS 125 depends on your license and the laws in your country.
Derestricting an RS 125 is not difficult if you’re familiar with working on bikes and can follow instructions, but it can be an expensive exercise.
Since 2003, Aprilia RS 125s have had four restrictions that need to be lifted to derestrict the bike: the electronic restriction in the CDI, the lack of a powervalve system, the catalytic converter in the exhaust, and the 28mm carburetor.
Once these restrictions are removed or the parts are replaced, you should see a significant increase in the bike’s top speed.
