BGM PRO silicone engine gasket set for Vespa Largeframe 2-channel motors

Silicone engine gasket set for Vespa Largeframe 2-channel motors 1959-1969 from BGM PRO

The BGM PRO silicone engine gasket set is specifically suitable for engines of the so-called LargeframeModels between year of construction 1959-1969.
These Vespa models can be recognized by the detachable engine side hood (with rubber seal) and a carburetor, which sits in a closed box directly on the engine housing (not on the cylinder).

This new seal kit fits the following models:

  • Vespa Sprint150 (VLB1T)
  • Vespa GT125 (VNL2T)
  • Vespa GL150 (VLA1T)
  • Vespa Super125 / 150 (VNC1T / VBC1T)
  • Vespa VNB
  • Wasp VBA
  • Vespa VBB

Compared to the later versions with three overcurrent channels in the cylinder / motor housing, these motors have a slightly different hole pattern for the screw connection of the housing halves. The BGM PRO sealing kit is exactly for these old housing shapes produced.

Silicone sealing set for 2-channelLargeframe buy

The seal kit also includes specific seals for the float chamber cover, the carburettor originally installed on these models (SI20 / 15, SI20 / 17).

BGM PRO silicone seal kits consist of a 0,5mm thick, high-quality coated sealing paper (like Piaggio “green” original). In addition, the seals, which are always in contact with oil, have an already applied layer of silicone sealant. This ensures an increased surface pressure on the seal. In addition, the silicone seal also seals the cold engine much better thanks to the permanently flexible sealing compound. So the engine always stays tight and the oil is where it belongs and where it is useful.

100% Made in Italy

The bgm PRO silicone seals are also available for many other models: Silicone seal

The poet - special seals for Vespa tuning

New seals for Vespa tuning engines

As a great alternative to the paper seals, we now offer new high-end kits for tuning kits (Polini, Malossi, Quattrini, Pinasco, Parmakit) Laser cut seals:

  • in a set with 3 different strengths
  • perfect fit
  • Space for customizing
  • made of the extremely stable Abil® N sealing material from Elring.

As a great replacement for the original seals, we still recommend the bgm PRO-Silicone seals for Vespa and Lambretta

Cylinder base gaskets in various strengths

Cylinder base gasket for Vespa

We have the cylinder base gasket sets from “Der Dichter” for almost all common Vespa cylinders in our program. The seals are supplied in a set, each with a seal in three different strengths:

  • 0,25 mm
  • 0,50 mm
  • 0,75 mm

Perfect for setting the cylinder control angle exactly and / or optimizing the pinch edge. You get the sealing sets in Scooter Center Shop.

 

Seals for porting and welded cylinders

Have you ported your cylinder and possibly also welded the housing on? Even then, these are the right seals for you:

All seals are provided with more material on the outside than the original seals. So you have enough space for custom buildings:

Seal for Pinasco housing

For the new Pinasco housings we now offer the seals in Set and also individually:
With Abil® N, of course, in a significantly higher quality material than that supplied by Pinasco - Pinasco 'only' delivers in brown paper.

Sealing set for Quattrini cylinders

We can now also deliver high-quality seals for the Quattrini M200 cylinder at a fair price:

Abil®N seals

Abil®N is based on NBR-bound cellulose fibers.

Abil®N is mainly used for sealing against hot and cold oils, greases, fuels and cooling water with corrosion and frost protection additives. Typical areas of application are control housings, gears, valve covers, oil pans,
hydraulic and pneumatic systems, chemical apparatus, pumps and compressors.

Easy to use

We recommend installing the seals dry or with a little grease applied on both sides.

All seals are cut with a laser and are therefore extremely precise. Abil®N is based on NBR-bound cellulose fibers.

Short fourth gear for Vespa PX and PX Lusso

,

Better gear connection with a short 4th gear

Short fourth gear Vespa PX

Why install a short 4th gear in the Vespa?

The short fourth gear is installed to improve the gear connection to fourth gear and that works very well with the short 4th gear with 36 teeth!
The short 4th gear for Vespa PX engines makes sense for every requirement, whether for everyday drivers, tourers or racers.
With 36 teeth this is a gear one tooth shorter than the original fourth gear wheel of a Vespa PX200.

bgm PRO - Premium tuning parts

The bgm Pro gear parts are made of ultra-solid material. The gear wheels are made for the highest demands high-alloy NiCrMo case-hardened steel (20NiCrMo2-2 / AISI8620).
The very good base material withstands even the highest engine performance. The precisely defined surface hardening to 58-60HRC makes the pinions extremely resistant to wear. Always consistently high quality. No compromise.

bgm PRO short 4th gear

Advantages of a short fourth gear:

  • more relaxed driving,
  • smaller gear step,
  • higher gear ratio with further optimization of the transmission
Now finally have an optimal gear connection from 3rd to 4th gear!

4th gear -BGM PRO- Vespa PX Lusso T5 125cc, PX200 Lusso (short) - 36 teeth

Short 4th gear Vespa PX Lusso Suitable for all transmissions that have a flat gearshift cross. These gears can be seen on the main shaft, which have a circlip in front of the gear wheels.

 

4th gear -BGM PRO- Vespa PX old, PX200 (short) - 36 teeth

Short 4th gear Vespa PX old. Suitable for all transmissions that have a cranked gearshift cross. These gears can be recognized on the main shaft, which have a circlip in front of and behind the gear wheels.

 

The middle segment on which the switch cross rests is at

  • PX old (until 1984, cranked switch cross): 5mm
  • Lusso (from 1984, flat switch cross): 6,5mm

The middle segments of the BGM gear wheels are larger (approx. 1/10 mm) and thus offer even more contact surface for the gearshift cross.

Scooter Center Technology TIP:

The short fourth gear can be ideally combined with the stocky longer 64 teeth BGM Pro primary gear. The overall ratio is in connection with a 24T clutch pinion significantly longer, Gear jump three to four but shorter. This means that the full engine power can also be used in Top speed be implemented.

Advantages of a short 4th gear:

When working on the gearbox, do not forget:

Especially interesting

So far, Malossi Sport and Polini 221 engines have emphasized combining with torque 24/64 reduction and a short fourth gear proven.

BGM6536L

By the short fourth gear, will the Gear jump from gear 3 to gear 4 reduced by a healthy amount, so that always with sufficient torque good aisle connection guaranteed and your scooter can pull through cleanly when shifting into fourth gear.

In the table below and the graph ** you can see how the difference works. With the longer reduction, you can already travel at a good speed for city or cross-country trips in the lower gears at a very low speed. In gear 4, the combination enables speedy travel at a reduced engine speed and the ability to reach a higher top speed.
