It was a dream and a amazing time to work at a motor manufacturer like KTM and working at the R&D department for the 2 stroke engines with Kurt Nicoll and Kees van der Ven and working and living in Austria. The dream was shattered by the bankrupt of KTM and Wilbert Bull went back to the Netherlands. Wibert uses the knowledge gained in the exhaust industry in which he has been operating now more than 30 years. Starting as a developer at BSM Exhaust Systems, later he later took the entire approval process for any licensed outlet under his wing. Since late 2010 he has been self-employed with Bull Special Products in Lichtenvoorde.
With Bull Special Products he develops and produces exhausts for the most diverse vehicles. About 1500 exhausts or exhaust parts per year leave the factory with an annual growth of 10%. Exhausts for Canta disabled vehicles and autocross, motocross and sidecar cross mufflers and systems. In addition, silencers and systems for the retro / vintage road and off-road motorcycles. A wide range of products developed and made with commitment and passion.
Meanwhile, there are many national, international and world titles he achieved in sidecar cross sport.
The development of new products is in full swing. Since 2017 there is the approval of the Department of Road Transport to be allowed to do under the name Bull SP approvals for their own developments. This is a crowning resisted work in recent years. For the foreseeable future Bull SP will make a major contribution to the development of new design exhaust systems and silencers for the retro market.
In 2023 the name has been changed to Bull Exhausts and the website and logo have been given a fresh look.
