Your Trusted Motorcycle Engineering Partner in Henfield
Established in October 1984, Boretech Engineering has built a distinguished reputation in motorcycle engineering, restoration, and MOT services. Founded by Andy Heitman at Golding Barn Raceway in Small Dole, West Sussex, the business initially specialised in cylinder reboring, crank rebuilding, and racing machinery preparation for Yamaha and Suzuki teams. Over three decades, we expanded our expertise to include off-road, road racing, grass track, and classic bike restoration, serving riders from novices to Grand Prix professionals. In 2014, we relocated to modern facilities at Henfield Business Park, enabling us to enhance our motorcycle MOT provision, road bike servicing, and advanced CNC engineering capabilities.

Our dedicated workshop now offers precision milling, turning, and grinding services for bespoke parts and production runs. We maintain a strong focus on classic motorcycle care, including specialist MOT preparation for vintage machines, while continuing to innovate with modern engineering techniques. Our team combines decades of hands-on experience with cutting-edge technology to deliver tailored solutions for every client.
