This lever is from a Sherco observed trials. It uses hydraulic clutch and brakes from Braktec brand wich already come with this bushings, but being made in nylon they get squished after some ground contact.
A lot of nice work there. I know how it makes a bike feel when it is properly customized and becomes an extension of you as you ride. That must be part of what makes you trials riders able to do the incredible things you do!
