The project “TP – Vincent”

After Terry Prince had built several ‘Vincents’ using an EGLI-Type chassis, Terry turned to his own concept. Based on the original HRD – Vincent main frame, the new design was improved with high strength aluminium milled out of billet

During a trip to Australia , Terry and Fritz jun. discussed the new design concept and its feasibility. Back home, Fritz Egli jun. began to explore the design using the latest CAD software . Raw sketches became engineering blueprints with calculated stiffness and torsional rigidity figures . In September 2012 Terry and Fritz jun, got together in Switzerland , they decided to put the project into action . Suter Racing then came into the scene. Suter Racing had the necessary production facilities and a specialized team to convert raw aluminum billets into stunning motorcycles.

In their time, the Vincent-machines had a reputation for being the fastest, most expensive and most exclusive motorcycles on the market. The most important models had 500cc single-cylinder and 1000cc V-twin cylinder engines. The 1000 Black Shadow (55 hp) and Black Lightning (72 PS) were still up in the late 1960s as the fastest production motorcycles.

Nowadays Vincent motorcycles are treated as exclusive rarities. With a few highly specialized enthusiasts around the World, the bikes are restored and repaired.

Oberwil-1It starts in the small Aargau village Oberwil/Switzerland in 1965. Fritz W. Egli sen., Then 28 years old, founded his Egli motorcycle technology in Oberwil, a few miles west of Zurich. This was the birth of the legendary Egli- spine frame constructed around the also legendary Vincent HRD 1000cc V2 engine. With his wife, Margrit (now Rusterholz) he lives in a back room of the workshop. In 1968, their son Fritz junior was born.

Terry Prince also joins in in this period . Together, the first Egli Vincents are produced and taken care of little Fritz junior. Terry is Fritz juniors godfather.

Fritz-jun-OberwilBeginning of the 70s , the paths diverge . The Egli motorcycle technology moves to Bettwil , where it is still located today. Fritz junior grows up with his mother in Hombrechtikon near Zurich. Terry Prince moved to Australia in the near Sydney , where he restores until today Vincent motorcycles and developes engine parts.

fritzThis name reminds most motorcycle enthusiasts of the senior, who set milestones with his EGLI-Type frames.

Fritz Jr. has a rich background as a technician . Among his employers, in addition to the father’s business, well known names such as the Formula 1 motor division of Mercedes-Benz Motorsport or Suter-Racing from Switzerland, one of the leading manufacturers in the international Motorcycle racing scene.

After his parents had separated in the early 70s , he grew up with his mother nearby Zurich. Early infected with the motorcycle virus, he had his first motorcycle as a 4- year-old child. As a Teenager tuning experiments were carried out on mopeds and discarded motocross machines and drove thorough testing in the fields of the step- father’s farm. To the annoyance of the local police also several high speed tests were held on public roads . At age 16 , after successfully completing secondary school, he began an apprenticeship as a mechanic in the spring factory Baumann in Ermenswil . Thus, the basic conditions for further development in the motorcycle technology were met.

In 1998 he designed and built a racing bike with Ducati 900SS Pantah engine and an EGLI-Type spine frame. This motorcycle may be one of the most potent 2-valve Ducati’s worldwide.

Also in 1998, began a four-year term as a racer with a national license in the classes Monobike, on EGLI-MZ Mastiff, and Promosport 600 on Kawasaki ZX600R. The highlight was the Swiss mountain championship title with the Egli-Mastiff, 31years after his father on Egli-Vincent.


For decades, he has been one of the big names in the Vincent – scene. His top-end kits (pistons, cylinders, cylinder heads, etc.) are used around the world by private Vincent- owners, racers and world record hunters.

Terry Prince lives since the late 70s near Sydney / Australia.
