All our oil filter kits include everything required to complete the installation using normal workshop hand tools.

Unlike most car engines, classic bikes suffer from very poor oil filtration, leading to comparatively rapid wear of the major engine components. Gauze and/or felt filters will trap larger debris but allow smaller particles, down to micron size, to circulate causing continual wear. Modern 20/50W detergent oils are designed to carry particles along to be effectively filtered out. Fitting an up to date replaceable cartridge filter will give an older motorcycle modern filtration levels allowing much greater engine life.

Available as a kit, this filter system comes tailor made to suit each individual model allowing easy fitting. I don't just supply the filter & let you work out how/where to mount it, everything required for installation is included in each kit along with full step by step instructions.

This is a proven modification with many hundreds of kits sold over more than 30 years.

On ALL kits the std. centrestand can be used.

The filter cartridge is used on Norton Commandos & is also a 2CV Citroen equivalent. so will always be available
