Re:
Limited I'm afraid due to how it mounts to the rear triangle.
Returning your existing shock is one of 2 options. They are simple units and it is not difficult to do yourself. Not sure if any service centre would do them, dont see why not though.
Other option is a risse shock. Pricey, as unless you can find a decent 2nd hand one, are upwards of £200 when you factor in import costs and postage from the states.
I want one for my rts, managed to get a basic unit here for slightly less than us costs, but would prefer the top of the line one, but at £350 I cant justify it.
What's wrong with your current one?
