SIP ROAD 3.0 racing exhaust for Vespa 125 - 150 Spint PX / PE / Lusso 24166230

Racing exhaust with a standard look. The MK 3.0 version of our slim SIP ROAD EXHAUST pushes the limits of performance once again.

The SIP ROAD was and still is the benchmark for all boxed pipes. It introduced the concept of a racing pipe that retains the boxed look of the original Piaggio Largeframe to a wider audience. And it made it as popular as it rightfully is today. Among its most attractive features are excellent rideability and easy tuning, especially on engines already running SIP ROAD 2.0. In recent years, many have experimented with an exhaust inspired by the original, and quite a few have even launched their own versions. Engines using this concept have achieved impressive levels of power and torque, and some have even surpassed the godfather, our SIP Road 2.0 box, in terms of absolute performance. Ease of use and torque delivery still need to be improved.

• Original appearance with original size box
• Massive pair, perfect for a daily cyclist
• Excellent for plug and play tuning with original carburetor

However, it was time to do better and develop a new gearbox. The benchmark was there, and the requirements were clear: it should still work with any type of engine. It should operate at low, usable real-world rpm, beat the best in that range, and still maintain the original gearbox dimensions. The new SIP Road 3.0 should remain slim and compact. The latter in particular proved to be a real challenge. Others use larger gearboxes to find performance, which, of course, makes life much easier. Unfortunately, squaring the circle takes time, so development took a while. The result, however, is worth the wait: a small gearbox that works well with a wide range of engine configurations while maintaining the best performance.

Affordable performance in any situation

It enters the powerband early, making the ride to work as enjoyable as tackling an Alpine pass. Our benchmark for development is kits like the Malossi Sport or Polini. But the Quattrini or Pinasco kits work very well with SIP Road 3.0. It's fantastic combined with an SI carburetor, requiring little effort to adapt and proven reliability.

Modern production and design

Achieving the performance level of the SIP Road 3.0 wasn't just a development process; manufacturing was also a bit more challenging. The downpipe isn't made of segments. It's a cold-drawn design with an upper and lower half. This helps minimize tolerances between the individual pipes and reduces the number of weld seams perpendicular to the direction of gas flow. Furthermore, this technique also allowed the downpipe to be routed around tighter bends without adverse effects. This was necessary to ensure the larger downpipe wouldn't collide with other parts, such as the main stand.

New quality with proven advantages

Significantly more torque and enormously more power. With a Malossi Sport on a P-Range, the power difference compared to the SIP Road 2.0 can be up to two hp. This is also true for the classic small-block setup. The A 177 Polini also achieved an increase of approximately 2 hp with the Road 3.0 compared to its predecessor. This promises relaxed riding without any problems when shifting gears. The SIP ROAD's sound is well-understated and doesn't attract unwanted attention, making it ideal for city riding and everyday use. Don't forget to adjust the jetting and ignition.

Conclusion: The SIP ROAD 3.0 is an excellent upgrade of a classic exhaust. All the great features of the MK 2.0—the fit, quality, and precision manufacturing—are retained, while power is slightly increased by about 2 hp. A racing pipe that resembles the original box exhaust. More torque and power, heat-resistant paint, excellent value for money.
