RealOEM and then compare local market parts to see what you need to change
Incidently the Swiss Market only version of one of my cars was limited to 300 bhp and had four cats in the exhaust revised ECU and smaller capacity injectors compared to the rest of Europe versions 2 cats - oh and it was 77bhp down on the UK and European version
97 K1200RS "Fixer Upper"
