Our has been designed to meet the demands of classic scooters.

No size has troubles with a short thread and can be used in small spaces without worries.
Please note: The mounting tool doesn’t need a long thread. You should therefore make sure that the minimum engagement depth is met.


Special tool for Vespa, Lambretta and Co.

Studs in the engine casing or the cylinder outlet are one example for special cases. These are tight spaces and the studs are very short. A standard roller type stud extractor would definitely lead to damages of the thread or will be limited in use, due to a lack of space. BGM72KT 001

Our BGM tool doesn’t strain the thread of the stud. The actual grip comes from the integrated ball, which grips the head of the bolt.
