BGM PRO Clubman Sport exhaust for Simonini killer case

bgm PRO Lambretta Sport Big Box suitable for the Simonini Mini Evo cylinder on the MMW killer case.

The alternative to the TSR Evo exhaust. Thanks to the early onset of torque and the ultra-harmonious power curve, this exhaust is a perfect match for the Simone. Based on the Big Box V4 but with a 25 mm diameter outlet for thermal relief and a rear silencer concealed under the engine for a pleasant and balanced sound. This makes the Big Box Sport the most powerful Big Box system ever from bgm.


The proven features of the Big Box V4 have of course been retained:

  • Brazed brackets
  • Bracket plates doubled
  • Revised insulation
  • Quiet
  • Larger volume of the exhaust body
  • Exhaust, manifold and body spring-mounted
  • Reinforced at all neuralgic points
  • Suspension as on the racing exhaust for perfect and tension-free installation
  • Removal without having to remove the right footboard or cylinder cover
  • The scope of delivery includes all parts required for assembly
