Silent block pair, engine -BGM PRO Original (soft)- Vespa PK 50-125, PK 50-125 S, PK 50-125 XL

Safe guidance with BGM PRO engine cable rubber sets

The BGM PRO engine silent rubber sets for the Vespa PK models are available in three versions: soft, medium and hard:

• Soft/Original: Almost identical to original Piaggio silent rubbers. Very comfortable, our recommendation for the everyday driver without sporting ambitions.
  Color marking: 2 x red

• Medium/Touring: Slightly firmer than the original Piaggio silent rubbers. Thus, significantly better driving characteristics without the everyday quality suffers. The reinforced rubbers have asymmetrical degrees of hardness. Therefore, despite tighter suspension, the ride comfort is maintained.
  Color coding: 1 x red, 1 x green

• Hard/Sport: For racing or the hard-boiled tuning friend who does not mind vibrations, but who places high value on the proverbial driving on rails.
  Color marking: 2 x green

For a high level of active safety, we recommend that you regularly change the engine silicone rubbers. These guide the entire engine block in the vehicle frame and transmit all drive, braking and steering forces. Together with the rider's weight and, if applicable, that of a passenger, intact silent-rubbers are very noticeable in that they are simply not noticeable.

Worn silent rubbers can be recognized by a spongy ride, similar to a tire with insufficient air pressure. To check, move the engine at right angles to the direction of travel. To do this, hold the vehicle with your left hand, grasp the rear tire at the 3 o'clock position with your right hand and try to push it away from you and pull it back in again. The engine must only be able to move slightly in the frame. If the motor can be moved noticeably in the frame, you should plan to replace the silent rubber in the near future. Installation is simple and is ideal, for example, in the course of an engine overhaul when the engine has already been removed anyway.

With the bgm engine silent rubbers supplied in pairs, the chassis regains directional stability, steering precision and stiffness.

TIP: Together with the silent rubbers, the shock absorbers/struts should also be checked regularly. Here, too, it is better to replace them sooner rather than too late.

ASSEMBLY

There are two different silent rubber systems for the PK models:

• Type 1: Two inserted silent blocks, each with a short steel tube vulcanized into it (like the BGM silent blocks).

• Type 2: A long tube and pressed-in rubbers which are secured on the tube by means of a circlip.

The BGM silent rubbers are suitable for both types. The old rubbers can be easily removed from the housing (lever out) for type 1. For type 2, the caulked retaining rings of the tube must be removed, the tube pushed out and the rubbers levered out. Then push the new BGM PRO rubbers back into the housing with a little talcum powder and, if necessary, use a non-recoiling hammer to adjust them slightly. Mount the silent rubbers dry, do not grease/oil them. Use talcum powder for easier assembly.

Please note: The silent rubbers in the Medium/Touring version (BGM7954) must be installed in the correct direction:

• Left in direction of travel: Red color marking

• In direction of travel right: Green color marking
