BGM PRO BigBox Sport – High-performance touring exhaust for Lambretta
The BGM PRO BigBox Sport exhaust is based on the BigBox V4. We call it “Sport” because it delivers more power across the entire rev range on all test engines. This makes it the most powerful BigBox system ever made by BGM. The power increase was achieved by redesigning the internal silencer chamber, which required a hidden silencer placed underneath the engine.
The exhaust body is compatible with existing manifolds, and the box itself can be easily swapped. It is available with manifolds for the following engine types:
RT195, RT225, original cylinders, Granturismo GT186, GT200, GT240 Mugello, Rapido, SR and other cylinders with oval exhaust ports
TS1 200, TS1 225, Monza and derivatives with round exhaust ports, using the matching exhaust flange
Quattrini M210 – requires matching Quattrini manifold and flange
Simonini cylinders on suitable casings such as the Killercase – requires a suitable manifold and TS1 exhaust flange
The proven features of the BigBox V4 have of course been retained:
Brazed mounting brackets
Reinforced bracket plates
Improved internal damping
Quiet
Increased body volume
Spring-mounted outlet, manifold and body
Reinforced at all critical stress points
Race-style mounting for perfect, stress-free installation
Can be removed without taking off the right floorboard or cylinder shroud
