Secure Guidance with BGM PRO Motor Silent Rubber Sets

The BGM PRO motor silent rubber mounts for Vespa PK models are available in three versions: Soft, Medium, and Hard:

• Soft/Original: Nearly identical to original Piaggio silent rubber mounts. Very comfortable, our recommendation for everyday riders without sporty ambitions.
  Color marking: 2 x red

• Medium/Touring: Slightly stiffer than the original Piaggio silent rubber mounts. This results in significantly better handling without compromising everyday quality. The reinforced rubbers have asymmetrical hardness levels. Therefore, riding comfort is maintained despite the stiffer suspension.
  Color marking: 1 x red, 1 x green

• Hard/Sport: For racing or the dedicated tuning enthusiast who isn't bothered by vibrations, but who values precise handling.
  Color marking: 2 x green

For high active safety, we recommend regularly replacing motor silent rubber mounts. These support the entire engine block within the vehicle frame and transmit all drive, brake, and steering forces. Along with the rider's weight and potentially that of a passenger, intact silent rubber mounts make a noticeable positive difference - you simply don't notice them.

Worn silent rubber mounts can be recognized by spongy handling, similar to a tire with too little air pressure. To check, move the engine laterally 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 and then pull it back towards you. The engine should only move minimally within the frame. If the engine can be noticeably moved within the frame, a replacement of the silent rubber mounts should be planned soon. Installation is easy and is ideal, for example, when overhauling the engine, when it is already removed.

With the bgm motor silent rubber mounts supplied in pairs, the chassis regains tracking accuracy, steering precision, and stiffness.

Tip: In conjunction with the silent rubber mounts, shock absorbers/struts should also be checked regularly. The same principle applies here: it’s better to replace them sooner rather than later.

INSTALLATION

There are two different silent rubber mount systems on PK models:

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

• Type 2: A long tube and pressed-in rubber mounts secured with retaining rings on the tube

The BGM silent rubber mounts are suitable for both types. The old rubber mounts can be easily removed from the housing in Type 1 (pry them out). In Type 2, the crimped retaining rings of the tube must be removed, the tube pressed out, and the rubber mounts pried out. Then push the new BGM PRO rubber mounts back into the housing with some talcum powder, and tap them gently into place with a recoil-free hammer if necessary. Mount the silent rubber mounts dry, do not grease/oil them. Use talcum powder for easier installation.

Please note: The silent rubber mounts in the Medium/Touring version (BGM7954) must be installed with directional orientation:

• On the left in the direction of travel: Red color marking

• On the right in the direction of travel: Green color marking
