The magic of the Aprilia RS125 begins at the carburettor, the all too often overlooked soul of the engine. If you want your RS125 ready for the track, there is no way around a perfectly tuned Dellorto VHSH. We overhaul that carburettor and set it up for a reliable fuel supply, a smooth throttle response and optimum top performance.
Start the engine and let the smell of burnt petrol bring the memories flooding back: the thrill of clearing your first hurdle as a young amateur racer on a rattly but dearly loved Aprilia RS125. The growl of the engine, the rhythm of the acceleration, every sense comes alive. For many enthusiasts, though, the real magic sits in the details, and that begins at the carburettor.
An icon of the sports bike world
The Aprilia RS125, an icon in the world of sporty motorcycles, was first launched in the early 1990s and has stolen many a heart since. This small but powerful machine has plenty to offer, but the secret of its true potential lies in the tuning of the carburettor. Once you experience the smoothness of the Dellorto VHSH, you understand how crucial a proper overhaul is. We work with precision and care to optimise your carburettor for top performance.
Fuel supply problems
One of the most common problems with the Dellorto VHSH on the RS125 is an inconsistent fuel supply. This leads to unreliable performance: the engine fails to pull hard enough or, worse still, lets you down at the crucial moments on the circuit. A professional setup ensures the carburettor is perfectly matched to your specific needs, whether that is a sporty setting for racing or a more forgiving setup for everyday riding. With our years of experience we know exactly which adjustments make the fuel supply crisp and predictable again.
Harmony in engineering
Compare your carburettor to a symphony orchestra: every note must be in perfect harmony with the others. On modern motorcycles, injection systems have taken over the work, but nothing matches the feel of a well-tuned carburettor. The sound of the engine, the sensation of a smooth throttle response and the joy of acceleration are unmatched. With craftsmanship and an eye for detail we overhaul and tune the Dellorto VHSH so that the authentic character of your Aprilia RS125 comes to the surface.
Craftsmanship and precision
The love of engineering and the accuracy we work with show in every aspect of what we do. An old carburettor can spring its surprises, and we know them all. Alongside the overhaul we also offer tailored advice on quality improvements for your motorcycle. Often a simple adjustment to the setup leads to a world of difference in the riding experience. Those are exactly the moments when you truly get to know and appreciate your bike.
Emotional value
We also understand the emotional value a nostalgic vehicle carries. It is not just a motorcycle, it is a piece of history, a source of pride and a friend you can always rely on. We keep your Aprilia RS125 in top condition, so you can head out on the road with full confidence.
