BGM
Sport version muffler -BGM PRO TOURING Box- for Vespa 50 N/L/R-Special
The BGM Pro TOURING exhaust offers a significant power increase
on short-stroke engines in the original look. True to its name,
the touring exhaust system is ideal for a fast street engine,
powerful yet visually and acoustically unobtrusive. It harmonizes
very well with common tuning cylinders from 75-112cc displacement, but it is
also clearly superior to the stock exhaust on a standard
50cc engine.
Beautiful original look of Vespa V50 models
Solidly built
Early and high torque
Good peak power
Wide rev range
Higher top speed
Also suitable for 3.50-10 tires
Very discreet
Handmade in Europe
Clear lacquered
The
bgm PRO TOURING exhaust fits without modifications to Vespa V50,

The technical solutions on this cylinder allow for performance that was previously reserved for long-stroke cylinders.
The cylinder is made of aluminum with a Nikasil-coated barrel and lamellar intake.
The head is CNC machined, with a viton gasket and secured with eight M6 bolts.
It has a bore of 54 mm and a stroke of 43 mm, 8 transfers
Exhaust port with bridge with an outlet diameter of 28 mm and stud spacing of 52 mm
Phases 113° intake and 171° for exhaust
The manifold has an internal diameter of 25 mm and is equipped with a four-petal reed pack.
Included in the kit are the original valve closure cap screws and a kit of paper gaskets of different thicknesses.
Recommended carburetor size: 19 - 24 mm

The Pinasco 102cc SRV "Zuerino" Ø 55mm thermal group is a new product dedicated to the world of Vespa 50 and Ape 50 with a 43mm stroke. Based on the famous Zuera 135cc, the 102cc SRV "Zuerino" features a transfer system very similar to that of its bigger brother, using the same RD350-type reed valve pack and the same flow guide, it mounts a single-ring piston with bi-conical pin, the new central spark plug head with 8 studs and centering bushings that definitively eliminates the problem of leaks and consequent performance drops with a compression ratio of 12.3:1.
The Pinasco 102cc SRV is a generous engine designed to make the most of power at low revs, its exhaust port has been designed to work correctly with original exhausts and commonly called "banana" stamped exhausts but can also be used in more advanced setups.
