About Bub Enterprises

Denis “BUB” Manning


A life in the fast lane... 
BUB Enterprises began in 1976 with Denis "BUB" Manning and a desire to build superior motorcycle exhaust systems. He immediately realized the need for a performance exhaust system for the very popular Triumph motorcycles of the day. Having many years of experience with the Triumph and other European brands like Norton, Moto Guzzi and others, Denis’s exhaust systems soon gained the respect of the Triumph community as "the best pipe out there".

Denis soon was able to expand the business to include exhaust systems for the Harley Davidson line of motorcycles and the new Japanese touring bikes.
As the business steadily grew Denis moved the entire operation to a 3000 square foot building perched atop a hill overlooking the valley on his northern California ranch.


 

As the company continued to grow Denis designed and built a brand new 15,000 square foot state of the art manufacturing facility in the small northern California town of Grass Valley, California. Nestled in the foothills of the Sierra Mountains, between Sacramento and Lake Tahoe, the deep, low BUB sound, can be heard emanating from the building.

 

 

The large building is also used as the main administration headquarters as well as our extensive research and development facilities. Also operating from this building are the offices for BUB Racing Inc. organizing the BUB Motorcycle Speed Trials at the Bonneville Salt Flats.

 

 

 

Denis Manning is a world renowned land speed racer. He’s designed and built some of the world’s fastest motorcycles. Amongst all of this Denis has continued to expand his own company, BUB Enterprises, to become a manufacturer of high quality performance exhaust systems for cruisers, sport bikes and ATV’s.
Denis Manning has worked in the motorcycle industry for over 40 years. In his early years he worked in a motorcycle shop, employed by racer Dutch Mueller, who was also known as ‘The Flying Dutchman’. Denis was soon nicknamed BUB (‘Big Ugly Bastard’) and thus became the name behind the legend.
Early in his career, Denis was offered a spot on the USA Drag racing team in England. After England his racing career took a turn. Taking inspiration from his childhood idol, Mickey Thompson, Denis headed off to the salt flats of Bonneville, Utah.

 

In 1968 he built his first streamliner. In 1970, at the tender age of 24, Denis built the world record breaking Harley-Davidson streamliner that was ridden by the late Cal Rayborn at 265MPH.

 

His racing career expanded from there, to building streamliners for Harley, Triumph, and Norton to name a few. In his career so far, Denis has designed and owned 6 of the 11 fastest motorcycles in history. His designs have included streamliners, conventional motorcycles, and on some occasions, LSR cars.
For over 35 years Denis has been creating motorcycles to capture the ultimate title of "world’s fastest motorcycle". He has dreamed of producing and promoting the sport of land speed racing. In 2004, along with his daughter-in-law Delvene, he began the International Motorcycle Speed Trials by BUB. Through this annual event he is able to provide the needs that are specific to motorcycle racing.

 

For the first time in history the International Motorcycle Speed Trials offered the opportunity for multiple riders to make official world record attempts. National Land speed records under the AMA have not been attempted since 1978 and in the lapse motorcycles have needed to compete at other events along side cars.
In addition to competing at these events with his latest streamliner, Denis, with the support of the industry, is advancing the sport of motorcycle land speed racing. Denis plans to continue to develop this annual event and with the sanction of the FIM and AMA present the opportunity for motorcyclists to place their names in the official record books.
Denis, with his wealth of experience in both motorcycle racing, and as a manufacturer of high quality exhaust systems continues to innovate, and support the motorcycling industry by being a leader in his field.

The BUB Seven Streamliner

will be back after the record in 2011!
