My rear ESA shock is leaking oil and it's softer than it should be but at 37000 I expected it. I know that there are a lot of posts about suspension and I was going to replace with Wilbers but now I want the water cooled GSA so I need to go cheaper. I believed that the OE shocks were a sealed and so a non serviceable unit but Firefox racing in North Yorkshire offer an ESA service for a bargain price. Has anyone tried them and if so what do you think or can you recommend anyone else.
