Exhaust -BGM PRO Clubman V3.0- Lambretta series 1-3 – not painted

Item no. BGM2105U3

This is version V3.0 of our BGM PRO Lambretta Big Box. This is a thoroughly revised version of the Lambretta exhaust, which comes with the well-known mechanic muffler version V2, but also with an overall improved insulation. Lowering the exhaust noises even more. Every plug and socket was further developed, overall and in terms of reinforcement. The engine support is one part, which was thoroughly revised. Resulting in a wider range of possible adjustments and perfect adaptation of your scooter / engine setup.

Lambretta Clubman exhaust BGM PRO Big Box 3.0

Mark Broadhurst fully exploited his experience in tuning of 2-stroke engines when working on the BIG BOX Clubman. With BigBox, Mark was successful in creating an exhaust, which looks almost like the original Lambretta series 3 exhaust. Mark successfully fitted the performance of an expansion chamber exhaust in the Big Box. Our Clubman is in terms of performance and revs on the same level as the legendary MRB Devtour exhaust, which, sadly, is no longer available. The BGM Lambretta Big Box V3.0 has high torque, a wide range of performance and a very nice development of sound. Many features are part of a series for the first time:

Advantages of Lambretta Big Box V.3.0

  • Same performance as an expansion chamber exhaust
  • Low noise level
  • Larger volume of the exhaust body
  • More ground clearance
  • Exhaust manifold for round (TS1 & Co.) and oval (RaceTour, Mugello, standard, …) exhaust stubs
  • Exhaust stub, manifold and body with spring suspension
  • All neuralgic spots are reinforced
  • Suspension as for racing exhausts for perfect and stress free assembly
  • Can be removed without detaching neither the footboard to the right nor cylinder cowling
  • An overall well-conceived design that works

 

Gloves for mechanic works on scooters:

Fine knitted glove BGM Pro-tection

The back of the glove is breathable, which grants special comfort.
100% nylon fine-knitted for perfect fit.

Vespa-Auspuff Touring

The steamhammer

The BGM BigBox Touring is the tour steamer on our programme.
Developed for a solid push beginning at low rpm.

An early performance delivery and the significant increase in torque make our Big Box’s Touring version an ideal companion for anyone who likes to travel as a couple or with a lot of luggage. Sidecar bikers will appreciate this one as well. Due to the high torque available it is no longer necessary to shorten the gear reduction, which is otherwise necessary!

Vespa-Auspuff Touring

On a standard PX200 the Touringbox already sets in 300rpm earlier than the standard exhaust, the previous king of all tour bikers. On powerhouses like the Polini or Malossi sports cylinders this exhaust is just fine as well.
Of course, the Bigbox has a double walled structure and is filled with damping material, just like the standard Vespa exhaust.

Vespa-Auspuff Touring

The BigBox Touring

  • Standard look
  • Quiet, thanks to double walled structure and damping material as in the standard exhaust
  • High torque
  • No performance drop
  • Rev range like the standard exhaust
  • Very discreet
  • Also fits the Rally/Sprint without the need for modifications
  • Massive construction with clamp at the cylinder
  • Handmade in Europe

EASY ASSEMBLY

The exhaust is mounted like the standard exhaust. The header is attached to the cylinder with a clamp. This provides a maximum of stability and prevents damage to the outlet flange, in comparison to a loose assembly with an O-ring seal. The header features spring mount tabs. For maximum ground clearance, make sure to use a spacer that is long enough at the rear shock.

Vespa-Auspuff Touring

WHAT WE RECOMMEND

With a longer gear ratio the available rev range can be increased enormously at every gear. That way, the high torque can be turned into speed.
The ideal thing is to simply mount the BGM Superstrong clutch with a 24 tooth sprocket (23 teeth is standard). It works without the necessity of any further engine modifications and leads to an increase in speed by ~5km/h.

Engines with plenty enough torque are also compatible with the bigger 64 tooth BGM primary sprocket combined with the 24 tooth clutch sprocket (+8km/h).

CONCLUSION
A lot of steam at low rpm – yeah!

Vespa touring exhaust BGM PRO BigBox TOURING Vespa 200cc

, ,

New Vespa touring exhaust

We received the first production pattern of the BigBox Touring for 200cc Vespa PX engines today.

Assessing looks and fit are part of a normal sample exam. And so are test runs on our Scooter Center P4 dynamometer.

We already mentioned in previous entries relating to this Vespa exhaust, that the BigBox Touring has a drastically smaller U-bend than the BigBox Sport, its larger sister.

BigBox P200_2

The missing black, heat-resistant cover layer makes the BigBox Touring look somewhat naked. We also attach significance to closely assessing all the joints without the cover layer, though.

BigBox P200_3

Test assembly on a Vespa Sprint with a 200cc engine

One of the first parts of the exam was the assembly in a Vespa VLB (Sprint). Usually space issues arise, when fitted in combination with a 200cc PX-engine. Especially around the centre stand, in particular in the “U’s” and the laps for the stand springs. Depending on the assembly of the exhaust, stand feed rubbers might collide with the U-bend.

We especially focused on these narrow spaces to see whether everything fits. The BigBox fits even to vehicles with a two-spring-system at the centre stand, which has only be introduced to the German market. The stand feed rubbers have a save distance to the hot U-bend.

BigBox P200_4

Just as its larger sister the BigBox Touring comes with a solid clamping and additional holders for exhaust springs.

You want to play it safe? Our retaining plate incl. exhaust springs perfectly matches your BigBox.

Performance measurement Vespa exhaust

Once we agree with the looks, processing and fitting we continue with performance measurements.

First “testing victim” is a cast iron Polini with 207cc, SI24 carburetor in a standard Vespa PX200 engine.

bigbox touring 200

Early torque for day to day use and touring

When developing the BigBox Touring we focused on having the possible torque available early and that there is a high amount of pressure in the exhaust with low revs.

The earlier and more homogeneous torque is provided by the engine, the nicer is a day to day drive. Our cast iron test engine by Polini with a BigBox touring reaches more than 18Nm at 3900rpm. Translated to the 4th gear this means smooth cruising at 50km/h with a very good potential to accelerate up to the final revs.

Increased transmission possible

Depending on the engine you fit the BigBox Touring on, an increased primary transmission can be used reasonably to go easy on revs while retaining the same cruising speed. Increasing transmission is easiest when using a clutch sprocket. The BGM clutch sprocket for Cosa clutches or a sustainable solution like our BGM Superstrong clutch are very fitting examples. An increased transmission may increase the top speed by 5km/h at same revs.

bgm BigBox Sport is available again

BGM BigBox Sport was just launched onto the market and was already sold out

We were really astonished: within a very short period of time the new Vespa racing exhaust (BGM1010SP) was already sold out. Due to positive feedback and tests, which have been conducted by several instances, it should have been clear. We are delighted about the immense success of this exhaust – Thank you very much!

BGM BigBox Sport is a thoroughbred racing exhaust, which gives a standard looking exhaust, that won’t arouse suspicion. It definitely is an alternative to conspicuous and mainly loud and big expansion exhaust chambers. Its willingness to deliver maximum performance makes it clearly stand out from other box pipes. Designed for performance oriented drivers, who hold an unsuspicious vehicle in high esteem.

bgm BigBox Sport performance chart:

LML150 5 port reed valve engine (reed valve intake) with Quattrini M1X cylinder (undealt) and 1.5mm head spacer (stroke compensation), SI24 carburetor Performance chart (BGM1010SP)

Need of a high performance engine concept

Just like any good racing exhaust, the sport box needs a high performance engine concept in order to develop full performance. Surrounded by cylinders like the Quattrini M1X and similar, the sport box offers impressing results. It easily supports engine performances above the 25 HP level and pushes with a rich torque. Despite its high top performance the sport box also supports leisure cruising.

Due to the commitment to a high gas flow rate, BigBox Sport is not suitable for standard engines or tame tuning cylinders. It needs a clear and strong pressure impulse in order to breathe life into the big manifold of the Sport Box.

PROS:

  • Standard looks
  • Low noise level
  • Top performance like an expansion exhaust
  • No performance slump
  • Broad revs range
  • Higher top speed
  • Very unsuspicious
  • Also fits a Rally/Sprint without modifications
  • Solid design with clamp screw at the cylinder
  • Handmade in Europe

CONS:

  • Not suitable for vehicles with 8 inch wheels (no sufficient ground clearance)
  • Not suitable for standard engines

To fasten the manifold at the cylinder you need a clamp screw. Compared to loose fastening with an O-ring sealing this results in best stability and prevents damage of the exhaust flange. For best ground clearance you should use a long spacer at the rear shock absorber.

Conclusion: pure understatement. Performance of a racing exhaust, looks and sound like a standard exhaust.
