Vertigo head inserts are made by S3. I understand the DL12 250 has got the low compression head which is Vertigo part number V-0616. The insert on my DL 250 has got S3 part number ST-0616 printed on it.
Vertigo part number for 250 high compression head is V-1027.
Looking on the 2020 vertical 250 parts diagram, it lists 0616 as the part number for your head. So you may already have a low compression head.
High and Low compression inserts for the 250 are also available from splatshop:
Does any know if a trials bike will fit in a SWB VW Transporter T5 / 6 Kombi (i.e with 2 rows of seats) with the VW ABS plastic (Motexion) Bulkhead fitted behind the rear seats?
Got a T5 just now and a single bike fits ok diagonally without the bulkhead, but can't find any info on the load space with one fitted.
