When building a special the options are endless, we can supply to accept components of your choice, we can also supply new components to create your rolling chassis. We welcome phone calls from prospective customers to discuss their project and specification, we will give written quotation after discussion and agreed specification. One main component missing from our list is the fuel tank, unfortunately, we can no longer supply these, this item would need to be sourced independently by the customer. However, we can supply all necessary fuel tank mounting rubbers, fuel taps and fuel caps.

Please be assured we can supply parts and accessories from a standard frame kit through to a rolling chassis using standard chassis components or special race-derived parts, or a mixture of both. We will always do our best to help you build your “ultimate street bike”.
