BOS is a Dutch manufacturer of motorcycle exhaust systems which has been around for decades. Over 50 years in fact! The design of any exhaust system naturally has to perfectly fit the usually ergonomic design of a motorcycle. All our systems are produced in The Netherlands using the latest technology by passionate people who are proud of every single muffler. The new range of Desert Fox exhaust is the result of quite a bit of research and development. Several prototypes later, the new line of exhausts began to take shape. However, the shorter length and the slanting lines brought about a good deal of technical challenges. The shapes of the exhaust box and the decorative bands were so specific they could only be produced by using laser cut technology. Furthermore, the bowls of the DesertFox series could only be realised by means of high pressure hydraulic fluid.
