The new Aprilia RX 125 and SX 125 have just been launched on the Japanese market, bringing a breath of fresh air to the small-cylinder motorbike segment. Despite specific updates for this market, such as the new instrument panel and redesigned LED lighting, these models continue to focus on lightness, agility and fun at the handlebars. However, there are no plans to commercialise them in the United States, where low-cylinder motorbikes still face some resistance.
The Aprilia RX 125 is a motorbike designed for off-road riding. With a set of 21-inch wheels at the front and 18-inch at the rear, fitted with CST studded tyres, this machine is ready to tackle trails, dirt tracks and back roads.
In terms of suspension, it has a 41 mm inverted fork at the front and a preload-adjustable monoshock at the rear, guaranteeing adequate travel to absorb irregularities in the terrain. Its double cradle steel frame keeps the bike light and sturdy, making it an excellent choice for both off-road beginners and experienced riders looking for an agile and fun motorbike for exploring nature.
If the RX 125 was made for the dirt, the SX 125 was designed for the tarmac. Using the same mechanical base, this version gets 17-inch wheels fitted with road tyres, offering greater grip on dry and wet surfaces.
With a stiffer suspension set-up, the SX 125 is an excellent choice for those looking for an agile motorbike for urban commuting or for fun on winding roads. Light and easy to ride, the bike’s handling favours aggressive riding, allowing for quick corner entries and even a few stunts, such as controlled rides and skids.
Although both bikes share the same 125 cc engine with 15 horsepower, their low displacement is not synonymous with monotony. On the contrary, the light weight of the RX and SX 125 makes them extremely responsive and enjoyable to ride, allowing you to explore the limits of the machine without excessive risk.
This type of motorbike has been well received in markets such as Europe, Japan and Australia, where driving licence regulations are stricter. In countries like the United States, where an 18-year-old can legally ride a 200-horsepower motorbike without prior experience, the 125 cc segment continues to be neglected. However, in markets with a more structured progression, these bikes are proving to be fundamental to the development of motorcyclists’ skills.
The Aprilia RX 125 and SX 125 are proof that a small-cylinder motorbike can be anything but boring. Whether for dirt tracks or city tarmac, these bikes offer an immersive, adrenaline-fuelled riding experience. Unfortunately, their limited commercialisation means that not all markets will be able to enjoy what are undoubtedly two of the best options for those who want to learn or simply enjoy the road without too much power.
