1973 Kawasaki Z1 "Concours" Restoration for sale.

General Information.

The small number of re-built concours machines we restore, are either for sale or can built to order for you.

Kawasaki Z900s have always been our speciality and we sell around 45 to 50 Z900s every year. Generally the Z1-900s we sell range from around £2500 to £10000 (for show condition). However, each year we restore two or three Z900s aiming for 100% "as new" concours condition, the best quality we can achieve. These are much more expensive. It would be possible for us to "restore" a Z1 for much less. Such a bike might look as good and cost only £8000 to £10000, but there would have to be compromise on the quality and extent of the work, which is not what we want to do!

Rebuild Specification.

On these fully re-built 900s every thing we can replace with new parts or restore to as new specification is done. We are setting out with quality as our objective and that means of course that we sacrifice cost! These bikes are very expensive to rebuild to this standard.

Each bike is completely stripped down and re-built using genuine new parts where possible and to original factory specification. The bike is completely stripped down and checked. Work starts from checking and re-jigging the frame etc..

The engines are stripped down and casings and castings cleaned by Steve Smethurst using a barrelling process. Our engines are fully re-built and work includes crank restored by SEP, new pistons and rings and re-bore as required and new clutch. The engine's head will be fully re-built with for example, all new valves, guides and seals as a matter of course. We expect to spend around £4000 - £5000 on the engines alone. And yes, if you would like metal plug caps we can fit them!

  • All chrome is mostly new or re-finished to as new specification.

  • Wheels are re-built with refurbished original rims, cleaned and refinished hubs and new spokes.

  • Our rebuilt bikes brakes have new master cylinders, disks and calipers (not refurbished items).

  • Work is completed by either by Steve Smethurst, or ourselves.

  • All colour options are available for each model.

  • Twin front disks are available (approx. £1000 extra).

  • Each bike is complete with tools and owners hand book, spare engine oil and Haynes workshop manual.

  • Full specifications are available on request and included with each bike.


Each bike is road tested and ready to go and will of course be warranted for 6 months. In addition we will be pleased to help with any advice, problems and servicing at any time.


Price includes free delivery in our van for up to 200 miles A to B distance. Any additional mileage is at 90p/mile A to B within the UK.

An International Delivery Service to any location is also available. Please contact us for a quotation. (Europe approx. £600, Australia by air approx. £1500, USA by air approx £1000).
