We offer a bespoke service to our customers, our philosophy is to first offer advice and brand new parts so the old ones need not be sent to us. However if new replacements are not available we may be able to overhaul the failed part. Our rewind and repair service is industry leading, we offer repairs for magnetos, generators and alternators whether British, European, Japanese or American. As manufacturers of electronic equipment we have in-depth knowledge of these systems, from the generator windings to electronic control units.
Our workshops are equipped with a wide range of electrical testing and system analysis equipment as well as CNC production mahines. We are a design and manufacturing company not a motorcycle repair shop and as such do not have the tools or equipment to work on complete motorcycles.
Our rewinds are carried out to the highest standards using only the best materials and industry practices by our small team of skilled craftsmen and women. Their services are in high demand and therefore lead times are beyond our control. It is in our interests as well as the customer’s to keep turn round times as short as possible.
Be assured that the front desk staff liaise daily with workshops and they will be in contact as soon the completed job has passed the inspection stage and is ready for return. The company has a strict policy of not disturbing the technical team’s daily schedule with telephone calls or expecting them to answer e-mails immediately. The company’s reasoning for this policy is simple, people are not able to progress the actual repair work to the required standard if they are continually being disturbed from the task in hand.
Basic tests: Simple tests with a multimeter or insulation tester are free of charge. Typically these take less than 3 minutes to perform. Results based on such tests are only opinions, not definitive nor binding.
Bench testing of CDi units: Analogue units £20 +VAT. Only confirms the unit makes sparks when triggered. Does not confirm correct timing curve.
In-depth tests: Often these can cost as much or more than a replacement part, so while we can carry out in depth analysis with the use of specialist test equipment the cost of doing so is significant. We have available the equipment to determine timing curves and performance of ignition and charging systems.

Repair work is chargeable per hour and workshop prices are always quoted excluding VAT.
We accept most major credit and debit cards over the phone or we can send you a secure payment link via e-mail. The payment link works well for overseas customers but you may need to contact your bank and inform them that you wish to pay a UK company.
Alternately you can pay by bank transfer in £ Sterling or € Euros – please ask for our bank details and which currency you prefer. It would be helpful if you would like to be billed in Euros to let us know when you send your parts to us.
Trade sales – to obtain the best discount payment should be by bank transfer.
Unfortunately we no longer accept cheques
The Lucas RITA (Racing Ignition Transistor Amplified) has a long reputation for performance and reliability. However thirty year old electronics will be tired or may have failed completely. Rex’s Revival circuit board now means that you up-grade it with all new, modern electronics but without changing any other parts of the ignition.
Designed to be compatible with the rest of the RITA system, Rex’s offer a high quality, modern circuit that fits inside AB11 & AB5 cases. The new unit is built and assembled in our own workshops and features the latest SMD components, ensuring excellent performance.
The new unit uses less power than the original RITA and features up-dates to the old design including reverse polarity protection, over volt protection and triple protection to the main transistor. The new unit is far tougher and less likely to be damaged than the original. Available for; Vincent, Moto Guzzi, Ducati, Moto Morini, Aermacchi, Hestketh, Japanese and British motorcycles that have a RITA fitted. Suitable for home fitting, comes with a comprehensive fitting guide. Our workshops are able to fit the new part to your existing RITA case for you.
Made in England
Many classic machines had alternators field windings fitted on to the crankshaft. These windings are connected to the regulator via brush gear.
We are able to overhaul rotating field winding type alternators found on many machines build in the 1970s & 80s. Specialist tooling is often required and has to be manufactured for each alternator type. New windings are made in-house, rotor windings are CNC wound then over-wrapped in a specially woven fabric. This assembly is treated with resin under a VPI process, assembled, tested for insulation strength then cured to form an incredibly strong composite, giving the windings increased resistance to centrifugal force. The finished assembly is checked for alignment to ensure the rotor runs true.
Slip rings are inspected, some types can be restored even if pitted, worn or burnt. We now offer a replacement slip ring assembly for the Suzuki GT750. Failure of the insulation that the slip rings are fixed to is often the cause of rotor failures on these models.
Racing ignitions require careful repair to get the best from them. Our CNC machines give the exact number of turns, wire tension and even layer build up. We have a wealth of experience with racing ignition systems and over the years we have carefully catalogued each one to create an extremely comprehensive reference database. As a result we can offer fixed price rewinds and fast turn rounds of these systems.
We can supply new ignition units or put modern electronics in to original cases to maintain original appearance for some of these systems.
We are able to test many older transistor and capacitor discharge boxes on the bench. Some repairs are possible where the electronics are not set in resin. If the electronics are fully encapsulated generally no repair is possible. We are able to manufacture an increasing range of new, replacement units to replace failed ones. Please check with us before sending your unit for testing.
-Resin filled CDi units are not repairable-
We restore many electronic parts to look like brand new original equipment with the benefit of modern reliability. This service is highly popular with restorers who are looking to achieve a perfect machine complete with its original electrics that work reliably. We offer:
We work to standards associated with overhauling aircraft components to restore rare motorcycle parts to ‘as new’. We have developed our own processes and equipment to strip and re-assemble parts without damaging them. Much of the restoration work is carried out in-house, with the excepting of plating and a few specialist processes.
We restore many electronic parts to look like brand new original equipment with the benefit of modern reliability. This service is highly popular with restorers looking to achieve a perfect machine complete with its original electrics that work reliably. We offer:
First the cases are stripped of the old electronics which are then professionally zinc plated to ISO 2081. Modern electronic circuits are built and test run before they are sealed to the refurbished cases. The unit is fully assembled, tested on the bench and the work is completed with a new set of decals and lead idents
New electronics, case professionally replated to ISO2081, new leads & connectors backed by a one year warranty
This model was normally fitted with electronic ignition but there was a points option for USA models. Its a very high quality competition magneto, with 2 charge coils to supply one set of points. We have in stock points and condensers for this magneto.
