Exhaust - BGM PRO BigBox TOURING (BBT) - Vespa PX200, Rally200 BGM1011TR

The BGM BigBox Touring - power for the big tour

Torque from idle speed with the look and sound of a standard exhaust.

The BGM BigBox Touring is the steam tour of our program.

Developed for full thrust from the cellar at low speed.

Perfect for original engines or cylinders that require early power delivery, such as Polini, Malossi Sport, and Pinasco. Early power delivery and significantly increased torque make the touring version of our BigBox the ideal companion for anyone who likes to travel as a couple or with a lot of luggage. Team riders will also be happy. The high torque available eliminates the otherwise mandatory shortening of the gear reduction!

On a standard PX200, the Touringbox revs up 300 rpm earlier than the standard exhaust, the king of all touring riders. On powerplants like Polini or Malossi sports cylinders, this exhaust is also the right choice. Like the original Vespa exhaust, the BigBox is naturally double-walled and equipped with insulation wool.

PRO

:

Original optics

Silent thanks to the double wall and insulating wool like the original exhaust

High torque

No performance gap

Speed band as original

Very discreet

It also fits the Rally without modifications

Solid construction with cylinder clamp

Handmade in Europe

WITH

:

Not for speed-oriented drivers

No approval

Please note: Choose the main jet approximately 4-6 numbers larger than the original exhaust.

ADVICE

With a longer gear ratio, the speed range available in each gear can be greatly expanded. This allows high torque to be converted into high speed.

Ideal: Simply install the BGM Superstrong clutch with 24-tooth sprocket (original 23 teeth).

It works without any other engine modifications and gives a ~5km/h advantage.

Engines with excess torque can also use the longer BGM primary gear with 64 teeth in combination with the 24-tooth clutch (+8km/h).

ASSEMBLY

The exhaust is mounted like the original exhaust. The manifold is mounted to the cylinder with a clamp. This provides greater stability than a loose installation with an O-ring seal and prevents damage to the exhaust flange. The manifold is equipped with spring straps. For optimal ground clearance, do not use a spacer that is too short on the rear shock absorber.

CONCLUSION A

lots of steam at low revs - yes!
