- Exhaust - LARCHOTEK Carezza Box (for Dolomiti 187 cc engine) - Wideframe, Faro Basso - Vespa 1953-1959, VM, VN, ACMA, VB1T, VGL1T, VL1T
High-performance box exhaust for the Vespa Wideframe—specially developed for the LARCHOTEK Dolomiti 187 and designed for strong torque, a broad power band, and a classic look.
The LARCHOTEK Carezza Box combines two characteristics that are not typically found together in high-performance classic Vespa Wideframes: modern engine performance and a discreet, nearly original exhaust appearance.
The exhaust was developed primarily for the LARCHOTEK Dolomiti 187 cm³ and tuned to its high-torque street and touring characteristics. The goal is not a narrow resonance peak at high RPM, but rather as much usable power as possible across a wide RPM range.
This makes the Carezza Box an excellent match for a wide-frame engine that needs to be fast in everyday use, on winding country roads, and on longer tours, without sacrificing its classic look in favor of a flashy resonance exhaust system.

Classic wide-frame Vespas thrive not only on their technology but also, and quite significantly, on their unmistakable shape. While a large external resonance exhaust system can enable high performance, it significantly alters the vehicle’s appearance.
This is exactly where the Carezza Box comes in. Its design is deliberately modeled after the classic box muffler, keeping it visually much closer to the historic vehicle.
At the same time, the internal design was not limited to the performance requirements of a stock engine. The Carezza Box is designed as a true performance exhaust for high-output wide-frame engines.
For a fast street scooter, maximum peak power alone is of limited significance. What matters is how much power is actually available across the usable rpm range.
The Carezza Box was therefore designed to make torque and power available across as broad a range as possible. The engine should deliver strong acceleration immediately after shifting up, rather than having to first reach a narrow resonance RPM range.
This characteristic is particularly well-suited to the Wideframe models. Their classic chassis and often rather long gear ratios benefit from an engine that delivers strong performance even in the mid-range.
The Carezza Box was primarily developed as an exhaust system for the LARCHOTEK Dolomiti 187. This means that the cylinder and exhaust are not simply random individual components placed side by side, but rather follow the same engine design philosophy.
The Dolomiti features a 187 cm³ displacement, a 60 mm stroke, and a diaphragm intake, and is designed as a powerful yet user-friendly street engine. The Carezza Box complements this character with an exhaust system that also emphasizes torque, a broad power band, and street-friendly rideability.
According to the manufacturer, the Carezza Box was developed with the goal of achieving the highest possible torque and power within its class. For practical use, it is particularly crucial that power is not generated at just a single point.
A strong torque curve facilitates acceleration from low and mid-range RPMs and allows for the effective use of a longer gear ratio. This reduces engine RPM at the same driving speed and fits perfectly with the character of a fast touring engine.
This approach makes particular sense for the Dolomiti concept: the large displacement is not intended solely to produce a high peak output, but above all to enable a smooth and responsive engine.
For many Wideframe riders, a classic look also includes an exhaust system that isn’t constantly the center of attention acoustically. The Carezza Box was therefore not designed as the loudest possible racing exhaust system.
Rather, the goal is to achieve a subdued sound level while maintaining high engine performance. This makes the system particularly suitable for vehicles that are regularly driven on the road and on longer tours.
Of course, the actual noise level also depends on the engine configuration, the intake system, the carburetor, the cylinder, and the condition of the entire exhaust system.
Although the Carezza Box was developed specifically for the Dolomiti 187, the manufacturer states that its use is not strictly limited to this engine.
As a result, the system may also be of interest for other performance-oriented wide-frame engines where a high-torque box exhaust with a classic look is desired.
For different cylinder kits, the exhaust port, space constraints, and the desired power characteristics should be checked before installation. Different valve timing, displacements, and exhaust geometries can significantly alter the performance of an exhaust system.
The combination of classic design, high power, and a wide RPM range makes the Carezza Box particularly appealing for vehicles that are actually driven.
On country roads, an engine with a strong mid-range is often faster and more pleasant to ride than a setup that achieves its maximum power only within a very narrow and high RPM range.
At the same time, the additional torque can be used to select a longer overall gear ratio. Especially on longer trips, this can result in a significantly more relaxed driving experience.
The Carezza Box is designed for compatible classic Vespa Wideframe and Faro Basso engines and was developed specifically for use with the LARCHOTEK Dolomiti 187.
| Series | Frame prefix | Period | Note |
|---|---|---|---|
| Vespa 125 Wideframe | VM | approx. 1953–1954 | Check engine and exhaust configuration before installation |
| Vespa 125 Wideframe | VN | approx. 1954–1957 | Check engine and exhaust configuration before assembly |
| Vespa 150 Wideframe | VL1T | 1950s | For the corresponding wide-frame engine assembly |
| Vespa 150 | VB1T | approx. 1957–1958 | For corresponding wide-frame engine assembly |
| Vespa Wideframe | VGL1T | 1950s | Check engine base and space availability |
The Carezza Box is also designed for compatible ACMA Wideframe models. Since historic French licensed models may differ in details depending on the year of manufacture and engine configuration, the engine base and clearance should be checked before installation.
On historic vehicles, different engines, cylinders, or previously modified components may have been installed over the decades. The actual engine and exhaust configuration should therefore be checked directly on the vehicle before installation.

A performance-oriented exhaust system alters the gas dynamics of the two-stroke engine and may therefore also require changes to the carburetor settings.
Especially when switching from a stock-style system to the Carezza Box, you should not assume that a previously suitable jet setting can automatically be used as-is.
The LARCHOTEK Carezza Box is the ideal exhaust solution for anyone who wants to extract high performance from a modern wide-frame engine without fundamentally altering the classic Vespa look with a conspicuous resonant exhaust system.
Especially when paired with the Dolomiti 187, the focus isn’t solely on peak power. What matters most is the broad power band with strong torque—a hallmark of a fast street and touring engine.
Added to this are the compact box design, the understated appearance, and a construction engineered for a pleasant sound. As a result, the Carezza Box fits perfectly with the core concept of the Dolomiti: modern performance for a classic wide-frame model, without unnecessarily altering its original character.
