Secure Ride 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 noticeably better handling characteristics without compromising everyday quality. The reinforced rubber mounts have asymmetrical hardness levels. Therefore, driving comfort is maintained despite the stiffer suspension.
  Color marking: 1 x red, 1 x green

• Hard/Sport: For racing or the hardcore tuning enthusiast who doesn’t mind vibrations, but places great value on the proverbial rail-like handling.
  Color marking: 2 x green

For high active safety, we recommend regularly replacing motor silent rubber mounts. These support the entire engine block in the vehicle frame and transmit all drive, brake, and steering forces. Together with the rider’s weight and, if applicable, that of a passenger, intact silent rubber mounts make a very positive difference – you simply don’t notice them.

Worn silent rubber mounts can be identified by spongy handling, similar to a tire with too little air pressure. To check, move the engine transversely to the direction of travel. To do this, hold the vehicle with your left hand, grip 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. The engine should only move slightly in the frame. If the engine can be noticeably moved in the frame, a replacement of the silent rubber mounts should be planned in the near future. Installation is easy and is ideal, for example, during an engine overhaul when the engine has already been removed.

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

Tip: In conjunction with the silent rubber mounts, the shock absorbers/spring struts should also be checked regularly. The motto here is better early than too late.

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 by a retaining ring 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 stemmed 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 a little talcum powder and, if necessary, tap them gently with a recoil-free hammer. Mount the silent rubber mounts dry, do not grease/oil. Use talcum powder for easier installation.

Please note: The silent rubber mounts in the Medium/Touring version (BGM7954) must be installed in a specific direction:

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

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