Like the Indian 101, Mabeco made 600 as well as 750cc engines.
It was pretty rude from Mabeco to make such a close copy of Indian.
It is said that by the time the lawyers could sue Mabeco, they were out of business…
Mabeco motors were built by Siemens.
Siemens is still in business, they are on the stock market and make all sorts of electrical/electronic/medical equipment as well as heavy locomotives and consumers appliances..
