ULTRALUBE

The latest generation of Superstrong clutches now has an innovative new technology: Ultralube.
Ultralube pumps (through precisely defined bores and centrifugal force) transmission oil both into the highly stressed hub profile (between clutch basket and clutch hub) and onto the clutch linings themselves.
This in the Vespa area unique technology makes the legendary Superstrong 2.0 clutch even more stable than it already is. A clutch designed to last.

PERFORMANCE

The ready-to-install clutch is designed for a power range up to approx. 20PS / 22Nm by means of the mounted clutch springs. Reinforced springs (sold separately, bgm PRO XXL Reinforced clutch spring) expand the performance range of the clutch to over 40 hp. It is still easy to operate.

DELIVERY

The scope of delivery includes the complete ready-to-install clutch with bgm PRO Cosa clutch facings and ten BGM PRO XL springs. A new O-ring for the clutch cover and a new crescent wedge are also included.

RECOMMENDATION

We also recommend a low-alloy gear oil of classes API GL3 / GL4 for high-performance engines in order to prevent the clutch from slipping even under extreme loads. This also applies to our bgm Superstrong couplings. The old engine oil specification SAE30 corresponds to today's transmission oil specification SAE 85W / 90. We recommend this as a lubricant bgm PRO Street gear oil (BGM2025, corresponds to specification API GL-3).

* In some cases it may be necessary to rework the clutch cover and arm, see Instructions & Video:

Vespa Cosa clutch plates bgm PRO Touring Alu

bgm PRO Touring Alu - our new clutch linings from bgm PRO - now retrofit a Vespa Cosa clutch with the properties of the Honda CR80 clutch linings

The bgm PRO Touring Aluminum facings are greatly improved clutch discs for all Cosa clutches. Revolutionary clutch linings in the Honda CR80 style with significantly more surface, but that Plug & Play fit into the normal Cosa couplings!

bgm PRO Touring Alu Vespa Clutch Lining Cosa

Clutch linings BGM PRO TOURING Alu type COSA2

  • Perfect symbiosis of racing technology and reliability for touring riders
  • Suitable for all conventional Cosa2 clutch baskets (strap width as original, 14mm)
  • Aluminum carrier material with reinforced contact surface on the tabs
  • Sinter pad material such as Honda CR80 in a wide design

The bgm PRO Touring aluminum pads combine the advantages of the popular CR80 racing pads with the high demands of touring riders.

Vespa Cosa clutch upgrade

SOLID BASE BRACKET

The linings use an aluminum carrier, the lugs of which have a large contact surface for the clutch basket. This makes the coverings very stable over the long term. The slow shearing of the tabs, which often occurs with conventional decks with steel girders, is completely eliminated due to the large contact surface. The aluminum also makes the coupling more thermally resilient. This is a great advantage in extreme situations (e.g. starting with a heavy load on a steep mountain pass), but also offers a reassuring reserve in everyday life. The width of the flaps is made to fit precisely, so that the pads are almost free of play in the basket.

DURABLE AND GRIPPLE MATERIAL

The lining material for the clutch discs is the same for the bgm PRO TOURING aluminum linings high quality sintered material as used for the CR80 racing pads. Due to the larger contact surface in the TOURING variant, the coupling is softer and not aggressive. The large support surface also improves durability.

Vespa clutch facing Cosa

 

FULLY COMPATIBLE

The bgm PRO TOURING aluminum clutch linings are available as 1: 1 replacement for conventional Cosa2 clutch facings designed. They harmonize perfectly with the standard steel discs.
The thickness of the pad package corresponds to that of the original, which means that no shims or spacers have to be used. The pads fit into all serial clutches of the Vespa Cosa2 models, into the PX125-200 models from year of construction 1998 as well as into all vehicles that have been retrofitted with a Cosa2 clutch. The linings are also compatible with clutches / clutch baskets based on the Cosa2 technology, e.g. clutch –SC-, MMW, Scooter & Service or Ultrastrong.  (Strap width as original = 14mm)

 

NOT SUITABLE

The pads are not suitable for clutches / baskets that have been specially manufactured to hold the CR80 clutch pads, e.g. BGM PRO Superstrong 2.0 CR80, ONKEL MIKE 'DDOG' CNC or similar (strap width CR80 = 16mm)

DELIVERY

The set includes:

  • 1x clutch cover plate (one-sided covering)
  • 3x clutch friction disks (facing on both sides)

Sufficient for a Cosa2 coupling.

CONCLUSION: The BGM PRO TOURING aluminum clutch linings are an ideal upgrade for your Vespa Cosa2 clutch.

For the Largeframe We equip the tried and tested models Superstrong with a 24 tooth DRT pinion off to the translation on an original 65 teeth primary gear to extend.

Especially with the current cylinders from Malossi and Poliniwhich provide a very high torque, it makes sense to lengthen the translation to convert the potential into speed.

This quality Vespa clutch is with 20,21,22, 23, XNUMX and XNUMX teeth available: Vespa clutch

You get a ready-to-install Vespa Cosa clutch with the supplied reinforced clutch springs in a performance range of 20HP / 22Nm works fine.
With separately available springs with a higher spring rate *, the clutch can keep up with setups without complaint significantly above 30 PS and is still easy to operate.

Features:

  • One-piece CNC milled clutch basket - Made in Germany.
  • The extremely robust construction offers perfect and precise guidance of the hub thanks to the shaft teeth.
  • The hub is made of high-strength steel to prevent the hub from cracking.
  • Thanks to the use of ten springs, there is sufficient spring force even for high-torque setups with little effort on the clutch lever.
  • Clutch basket hardened by nitriding, worn out clutch baskets are a thing of the past.
  • Always precise cutting thanks to the pressed sintered bushing.
  • Every coupling is subjected to a quality control. In this way we guarantee that we will deliver a functioning and ready-to-install coupling.

The scope of delivery includes the complete ready-to-install clutch with bgm PRO Cosa clutch linings and ten reinforced springs. A new O-ring for the clutch cover and the crescent wedge.

 

TECH TIPS:

The number of teeth on the clutch is important for the length of the total reduction. This can also be varied. Possible combinations:

  • Original 20 teeth: 21T, 22T
  • Original 21 teeth: 20T, 21T, 22T
  • Original 22 teeth: 20T, 21T, 22T
  • Original 23 teeth: 21T, 23T

For models up to and including 150cc, a small cast aluminum lug in the motor housing must be removed to mount the clutch. This can be easily snapped off with larger pliers. With some clutch covers, minimal material has to be removed from the drip nose at 12 o'clock in the area of ​​the radius.

The Vespam clutch can be installed in almost all engines of the so-called Vespa Largeframe Class. These are all vehicles whose chassis prefix is ​​three-digit (e.g. VNB, VNL, VNX etc., the addition 1T, 2T, 3T is not taken into account) and which have the carburetor installed directly on the engine housing (not in the frame or on the cylinder). On some old vehicles before the Vespa PX era, the thin washer (1,5mm) under the clutch has to be replaced with that of the PX models (3,3mm Item No. 7671297 http://www.scooter-center.com/product/7671297).

16 springs for even contact pressure

When it comes to springs, we use tried and tested methods. sixteen bgm Pro XL springs ensure even contact pressure.

Vespa clutch bgm Superstrong for Vespa Smallframe

Due to the number of springs and the arrangement on the largest possible extent, a very even pressure behavior is achieved. This effectively prevents the two pressure disks from tilting or locking.

Thanks to the perfect coordination of spring stiffness and number, paired with the stiff design of the pressure plates, the clutch can be operated easily even with a PK-XL1 clutch cover.
The contact pressure of the bgm Pro XL springs and the coefficient of friction of the Racing red pads have a Test in our X-Mas duel already withstood the 30PS.

Highly stable & well thought-out coupling hub

The clutch hub is designed for a primary with a shock absorber and has an M28x1 internal thread for pulling off. (The extractors of the Vespa fan wheels with electronic ignition fit there.) Thanks to the internal thread, the area around the cone could be made much more massive. The more stable design without the senseless weakening by an unnecessary keyway makes the hub the first choice for every load. We recommend our for assembly Coupling nut and threadlocking.
