About us

Race Developments is an engine building, tuning and specialist race parts design company based in Gloucester, England.

Our main area of expertise is in cylinder head development, race engines and engine managment set-up.
Most of our work is for 4-stroke motorcycles and our engines not only compete in events around the country, but all around the world. We have developed engines running in World supersport and the American AMA series.

Using 14 years of engine building experience, we pride ourselves in building strong, reliable and powerful competitive engines. Testament to this is the grueling punishement our race engines get at the famous TT and ManxGP events.

Race Developments aim is simple - to combine well proven engine building experience and techniques with the latest in flowbench and computer modelling technology.
Not only are we involved with the latest development and engine buildings, we are also the only Dynojet Approved Power Commander Tuning Centre in the Gloucestershire area. So if all you require is the mapping and set-up of your Power Commander then we can gladly cater for this too.

You will feel safe with our curtious, highly trained and knowledgable staff.
So, no matter what your requirements are....from engine fuel mapping to superbike engine building you will always be welcome and made to feel at home.

We hope you enjoy the site and thank you for visiting.
