I have a 54 Reg. Was thinking of upgrading the brakes to 300mm x 24mm (front) & 253mm x 9mm (rear). It says to aquire st170 brake calipers? and advise on fitting? Thanks!

There are 2 guides in our how to section. No pics at the moment as there are problems with our image uploader but it gives you an idea of whta needs to be done.

Rear brake upgrade

Front brake upgrade

Hope this helps
