but you will need a fitting kit to make sure the seat fits properly.

There's loads of previous threads on this but here's the main steps:

* Remove your Bip seat unit
* Remove the rear light fittings
* Replace the triangle shaped bracket at the rear with one from the kit, plus some spacers.
* Refit the lights to new seat
* Fit the new seat unit and align the locking bracket.
