[QUOTE=SteveHall;87990]Does it matter whether it is a right-hand drive or left-hand drive bike?

Strange as it may seem, it does for many bikes. My UK bike couldn't get through the ITV test in Spain, required to register it here, as the lens on the headlight shapes the beam. In UK the beam is not just a flat beam, rather it is dipped but with a raised part of the beam to the left. Apparently this is to enable one to read roadsigns. Simply redirecting the beam to the right for mainland Europe means the raised part of the beam is now pointing at oncoming traffic.

Getting a headlamp made for mainland Europe changes the bike from lefthand drive to righthand drive. Careful though, the ITV station in Algorrobo wouldn't accept a US headlamp as it didn't have the European E stamp on it. The US DOT stamp didn't satisfy them.
