We offer two levels of service; a bespoke restoration service for owners looking to attain the highest levels of originality where original units are fully restored with plating and decals where required. The second service is aimed at owners who simply require parts repaired to the highest standard but without concours finish to the metalwork. We offer a wide range of services from the design of new electronics to fit inside OEM metal cases to new ignition units in lower cost plastic boxes.

Rex’s have been synonymous with the repair and manufacture of new electronics for Kawasaki triples for over ten years and have in-depth specialist knowledge. We have an active and ongoing development program for the Triples building on the services we currently offer. Our workshops have comprehensive test equipment so we can trace faults as well as fully test every part we manufacture before it is dispatched to the customer.

We offer new replacement regulator rectifiers, HT ignition coils, new stators and a industry leading rewind and restoration service.

We are also happy to fit new electronics in to metal cases the customer has prepared and had replated.

We fully support our own electronic ignitions with a fast and effective spares and repairs service. All XT500, DT250, DT360, DT400, TY175, TY250 & SWM ‘RMK’ kits are covered. As the original manufacturer we have the knowledge and equipment to fully test, trouble shoot and get you going – fast!

Unlike most of our competitors, we offer full servicing, spares and repair of our own electronic ignition up-grades!  All parts in current manufacture are made available as spare parts, in case they are ever needed. We will always do our best to get an older kit going again for as little as possible and less than the cost of a new kit. Where we can we will try and save you money!

Some of the the very early systems are no longer supported, but again we will look at options to save you money.

We stock new parts ready for quick dispatch. There is no inspection fee on RMK kits.

– RMK CDi units

– Source windings

– HT coils

– Stator Looms & hardware packs

Made in England

New windings are made in-house on CNC machines. Stator windings have to have several sets of special tooling made, for the models above we have them ready to hand. The only ‘problem’ with any of the above systems is that they are now over 40 years old. When properly repaired to high standards the original equipment proves to work without any problem, also machines that are completely standard will always fetch more money.

We find that at this age the Suzuki GT750 rotors suffer low insulation resistance on the slip ring assembly. The only option is a replacement, for which we have a repair scheme.

Voltage regulators that fit into original cases and period repreduction rectifiers are now possible.

We hold stock of all the parts for Pazon ‘Sure Fire’ kits and can test these ignition systems under real load conditions. Please note we deal with warranty only where the customer has proof of purchase from us and up to one year from date of purchase. We can look at kits brought elsewhere, but you will be charged at our standard rates in this case. We gladly take on work for all customers who don’t want to wait to return kits to New Zealand.

Tri-Spark kits – we are able to run many of these systems these under real load conditions. Please note we deal with warranty only where the customer has proof of purchase from us and up to one year from date of purchase. We can look at kits brought elsewhere, but you will be charged at our standard rates in this case.

CDi units. We can fully test all CDi units we manufacture, and the original systems they fit. For all others please check.

Ignitech – We charge per ‘plug-in’ to alter progamming and for testing.

Important – Please check BEFORE sending units for testing. We charge a handling fee and return postage for all items sent to where work is not possible.

We offer a low cost flat fee for a check of these items. We are able to test most regulator rectifier units, rectifiers and HT coils. However if you unit has no wires, just a pins in a plug please provide a clear diagram of which wire colours go where.

We offer a low cost quick test for a flat fee which is great if you need to know if a parts is working or not or breaks down under load. Should the customer require indepth testing under loaded conditions we can provide this but this is not included in our low cost ‘yes/no’ test fee.

Important – Please check BEFORE sending units for testing. We charge a handling fee and return postage for all items sent to where work is not possible.
