For us quality is paramount so along with carefully selected products from other suppliers, we offer our own range of products manufactured here in the UK, products you can depend on, from a simple voltage warning light to a complete charging and ignition system. All of our electronics are subject to on going quality testing in our own workshops to ensure ease of use, first class performance and long life. As designers have the equipment and knowledge needed to fully check and develop systems and system components. Should you need help with one of our products you will find a range of helpful guides and advice sheets below* If you need further assistance e-mail the technical team and one of our technicians will be able to answer your enquiry. To avoid mistakes being made in the workshops our techs are not immediately contactable by telephone.

Help sheets, articles & advice - free to download stuff.
Below is a selection of trouble shooting guides, useful background information and fitting guides that you may find helpful. The documents are free to download.
Our publications must be used in conjunction with the manufacturer's workshop manual and do not override any safety precautions the machine's manufacturer give. Some documents may go in to greater detail through our experience of in-depth strip down of components, we provide this data to make fault finding more accurate.
Our fitting guides do not set out to teach you technical skils, instead guide you through a process that is either poorly explained or not covered in the shop manual. We give many tasks a technical rating to help you decide if you will need professional help:
Good working knowledge and technical understanding are necessary
A basic mechanic's tool set is all that is normally needed
Suitable for the home mechanic who is happy doing routine servicing such as oil changes and minor adjustments following the manual.
An in-depth working knowledge and good technical skills are required.
A good tool kit and some special tools will be needed
Suitable for those who can carry out all servicing and many repairs such as bearing replacement, top end rebuilds plus being able to use engineering tools such as micrometers or a DTi.
Expert level, good problem solving, extensive knowledge and experince.
Comprehensive tooling, possibly access to an engineering shop.
Suitable for those who could fully strip and rebuild an engine, fabricate new parts from raw material or experienced engine tuners.
Technical Publications & Useful Information
We've noticed that some guides were written quite sometime ago, we are up-dating many of the testing guides with more concise information to aid the professional mechanic and home mechanic alike.
Increasingly we are being given voltage readings taken when kicking the bike over. These are meaningless tests as there is no way of telling a good reading from a bad one. This is no way to test a stator. Such tests are not approved so may invalidate warranties on new parts - something not mentioned on the forums! Worse, some systems generate surprisingly high voltages, even an un regulated alternator can give an extremely nasty belt as it may be producing 100 volts or more with the engine running. Again something not considered by those who give poor advice with no thought of the safety of others. The reason manufacturer's don't tell you to do such testing as it can expose you to dangerous voltages!
We have improved on the information given in the workshop manual in all testing guides dated 2018 on, we are getting to the others and will be adding more very soon!
The tests we prescribe will not invalidate warranties and will keep you safe.

All Rex's fitting guides must be used in conjunction with the OEM bike manufacturer's manual for that model. It is the responsibility of the person fitting the parts to ensure they have the correct technical data, tooling and test equipment. No part of any PME guide over-rules any safety precaution given in an OEM manual.
