Secure Ride with BGM PRO Motor Silent Rubber Sets

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

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

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

• Hard/Sport: For racing or the hardcore tuning enthusiast who doesn't mind vibrations, but who places high value on the proverbial ride on rails.
  Color marking: 2 x green

For high active safety, we recommend regularly replacing motor silent rubbers. These support the complete 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 rubbers have a very positive effect, as you simply don't notice them.

Worn silent rubbers can be recognized by spongy handling, similar to a tire with too little air pressure. To check, move the engine perpendicular 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. The engine should only move slightly in the frame. If the engine can be noticeably moved in the frame, a replacement of the silent rubbers should be planned soon. Installation is easy and is ideally done during an engine overhaul, when the engine is already removed.

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

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

INSTALLATION

There are two different silent rubber systems in PK models:

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

• Type 2: A long tube and pressed-in rubbers that are secured by a retaining ring on the tube

The BGM silent rubbers are suitable for both types. The old rubbers 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 rubbers pried out. Then push the new BGM PRO rubbers back into the housing with a little talcum powder and, if necessary, tap them in gently with a recoil-free hammer. Mount the silent rubbers dry, do not grease/oil them. Use talcum powder for easier installation.

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

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

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