This listing is for the insert only, it does not include the head! The second picture is to show you which TSP head it suits. If your model head is the older two piece design, this will not work.
This is the listing to buy additional compression inserts to suit your TSP 250 head from 2008 models to current with the removable compression insert design, regardless of carby or TPI. The new head was designed for the intention to easily change the head inserts to suit different riding situations, while offering them at a cost effective price.
This insert will come with the inner o-ring required.
