Eurotech Engineering Trikes was a British specialist in motorcycle-to-trike conversions active during the 2000s and 2010s. Based in Kent and later St Leonards On Sea, the firm became known for its bolt-on conversion kits, allowing motorcycles such as Triumph, Honda, and Yamaha tourers to be converted into three-wheelers without permanent frame alterations. Among its designs was the Hammerhead conversion, a rear-end assembly distinguished by its wide track, independent rear suspension, and automotive-sourced components, aimed at improving stability and ride comfort compared with rigid-axle trike conversions. The Hammerhead was marketed as a high-quality solution for riders seeking the touring ability of a trike while retaining the handling characteristics of a motorcycle front end.
