MB & bgm Vespa exhaust Big Box - update
Vespa exhaust bgm PRO
NEW: Vespa sports exhaust Big Box Sports
Today we proudly present you the first pictures and the first results of the test bench runs of our new one bgm PRO exhaust systems for the Vespa.
The Vespa Big Box exhaust was developed in close cooperation with MB in England and is also the result of over 20 years Scooter Center Experience.
Advantages of the exhaust:
- More efficient:
- powerful like a resonance exhaust
- significantly easier to turn than SIP Road
- very wide speed range
- no performance hole like a reso exhaust
- Looks like the original
- Quieter than racing exhaust
- 200 mm outlet socket with Viton® Oring -> no more cracked exhaust ports on 200 mm aluminum cylinders
- massive, thick-walled material
- so far without approval
- with serial number
Purpose of use:
Due to its original look and its low volume, the exhaust is particularly suitable for original tuning or touring setup.
Due to its power delivery, it can be used universally on original as well as heavily tuned engines at home.
First pictures:
Here are the images of the prototype. The exhaust will be available for the following models:
- Vespa PX 200 / Vespa Rally 200
- Vespa PX 125 / Vespa PX150 / Vespa SPRINT etc.
launch
We expect the exhaust from the beginning / middle of summer and are really looking forward to it. The test drives were great.
Test run performance diagrams:
The exhaust systems were made on the professional Scooter Center Ammerschläger P4 test bench tested with laboratory software:
Result: Significantly more power! eg:
- + 2PS more on PX200 compared to the original exhaust with significantly improved revving = top speed
- + 3PS more on Malossi 210 compared to comparable road exhaust systems
- + 5PS more on Malossi 166 (60mm shaft, exhaust made, 28mm carburettor on rotary valve) opposite Vespa Road exhaust
As a Test roller the following candidates were available:
- Polini 207
- Polini 210 Torque miracle
- 12 HP original engine
- Malossi 166
- Polini 177
The test runs were all done with the engine warm. The tests were carried out against the existing exhaust systems on the vehicles and against the SIP Road exhaust.
Almost all scooters were then tested for several kilometers on the road in order to really feel the change. That was the very subjective so-called Popometer test ;-)
The conclusion
Awesome part - this is how a Vespa exhaust has to be!
Both for the "laboratory test" with performance diagram and for subjective testing on the road:
The new bgm PRO exhaust puts you in a good mood. The engine turns out much more freely, the Vespa becomes much more flexible and faster and without the consumption or volume increasing noticeably.
Beautiful curves,
unfortunately I don't see any pictures under first pictures? !!
should mean pictures ......
Pictures are now online.
Price?
200 with Viton approx. 179 euros
125/150 without Viton approx. 159 euros
Very interesting but why not a 125/150 with Viton.?
Hallo,
because this is not necessary with the small cylinders.
Manufacturers only have manufacturing tolerances for the 200 Vespa cylinders.
Regards
Heiko
How much and how soon will it be available for purchase? : D
Version for 200cc 179, - Euro
Version for 125 / 150cc without Viton 159, - Euro
Available mid / end of July - we can't wait ;-)
Is the 125/150 (without Viton) also suitable for a PX 80 with a 135 DR?
Greeting Markus
Hi Mark,
yes exactly, it fits and would be a great exhaust for it.
Regards
Heiko
why won't there be any for the T5?
especially with the t5 there is little choice in o-optics.
Hi Bobo,
I can reassure you - the Vespa T5 bgm Big Box exhaust will be the next project.
First come the Vespa PX exhaust systems, then we optimize the exhaust for the Vespa T5.
Regards
Heiko
:)))) Today is a nice day :))
:-) That makes me happy!
Does it also fit on a Cosa 2 aluminum cylinder?
Hi Stefan,
after modification: since the Cosa 200 has a thicker engine cross-member, you would have to remove the rear bracket of the cross-member bracket on the exhaust.
And the bgm exhaust only fits on cylinders that have the exhaust not is screwed onto the manifold.
But you can also install a PX200 cylinder.
Regards
Heiko
Thanks Heiko,
I feared that ...
Too bad. Looking for something with a screw connection ...
Hi Stefan,
as I said, et. at the next occasion you swap the cylinder of the Vespa Cosa ... then it goes with the bgm Vespa exhaust.
Regards
Heiko
Can I already order one?
Hello Jochen,
not yet officially - we are working on it.

Is there video so you can hear the sound?
Hallo,
good idea, I'll suggest that.
Regards
Heiko
Hello!
Can you perhaps say more about the Malossi 166 setup or the Polini 177 setup? Tax times etc?
lg
Hi Andi,
I only know this:
Malossi 166 (60mm shaft, exhaust made, 28mm carburettor on rotary valve)
But try to get more information.
Regards
Heiko
Is there in the foreseeable future, or can you also manufacture such a performance-enhancing exhaust in Ori design for other vehicles?
In my case Hexagon 180, so to speak `a Gilera Runner exhaust with more power and torque than the original?
Hello Frank,
no unfortunately this is currently not planned for a Hexagon.
Regards
Heiko
I'm looking forward to a sound video.
recently bought a Px 125 for my girlfriend.
since the performance doesn't knock me off the table, i have to do a little something.
would suit me all right.
there is a lot of talk about the bgm in austria.
lg from austria
Hello Gerald,
with the 177 Polini in connection with the bgm you would have the underperformance off the table.
Stupid if your girlfriend drives away from you ;-)
Possibly just the exhaust is enough ...
Greetings from Colonia to Austria
PS seen the postage-free campaign for Austria?
Hello Gerald,
here the promised video:

Hey people!
After my Simonini (southpaw) gave up the ghost, I urgently need a new one.
Does the BGM get to the Simonini?
Basically it went pretty well with my 177 Polini (on 125 PX) and 24 SI, but it was already too loud for me.
I do not want “performance losses”. I am also grateful for other suggestions. A left-hand boom is also welcome;)
Should be suitable for touring in any case!
Thank you and LG from Austria,
Earl
Hi Earl,
Simonini was supposed to beat Simonini in all respects. On the 166 (see diagrams) it is even better than the PM.
And when will the part finally come? Waiting longingly for it;)
We're counting the days until the things are finally here, impatient.
Fortunately, it won't be long until the beginning of September ;-))
And you can already pre-order via the shop: http://www.scooter-center.com/search?query=vespa+bgm+big+box
That thing looks great!
Is there a performance comparison on Malossi?
Malossi 210 on membrane - BGM against Pep3?
If you “hit” it with it (torque / power / speed range), the thing is bought unseen!
I just assume that it is quieter, because it doesn't get any louder than the Pep3.
I am happy to provide my motor / scooter for tests….
A test comparison against the silent boxes from Pipedesign would be interesting. Because that should be the direct opponent. And not the Sip Road ...
A big box for 200 and one for 80-150 are available here. If you want to put it to the test to test it against your current setup, you are welcome at any time (but by prior arrangement)?
is it planned that you have a TÜV certificate made?
then you can have the thing entered without drama if the occasion arises.
Hi Joerg,
this will probably not be so easy to implement due to the increased performance.
Hi Philip!
Delivery starts today!?! * hand rub *
Yes and no, the systems are ready and on their way to us. We hope to be able to deliver next week.
Hey there!
What is the current state of affairs with regard to the possible delivery time?
LG!
God willing, next week. As I said, they are on their way and unfortunately we only have limited influence over that.
Wondering if it will work with large frame vbb / vnb running 8 ″ wheels? Is ground clearance going to be a problem?
Thx,
Eric
Hi Eric,
We haven't tested that yet. But I think the ground clearance should be okay and not very different from a standard P range box. The limiting factor is always the width of the exhaust on standard pipes. On a full expansion chamber pipe the limiting factor on ground clearance is when the pipe tilts over.
Hallo,
When will the BigBox for the T5 finally be available? I had already seen in November that you had it in the shop but it was not available and it is unfortunately still not available today. Is there an exact delivery date?
Hi Jan,
no - unfortunately not yet - we will keep you up to date here in the blog!
Hallo,
what about the news for the PX80? Is there anything new?
gruß
Hi Stefan,
no - unfortunately there is no news yet regarding the Vespa bgm PRO BigBox exhaust for the small engines - here in the blog we will keep you up to date!
I have the problem with the volume. If you drive a Px 125 with a DR 177 with a Sito plus, the Pro BigBox is quieter.
Mfg Stefan
Hello Stefan, purely in terms of hearing, the BigBox is significantly quieter. But this has primarily something to do with the lower and therefore more pleasant frequency of the BigBox, not with measured values. In other words, the Sito Plus often has an extremely uncomfortable pitch that eats into your hearing. The BigBox sounds much more like an "adult" series exhaust;)
