Bought this for a full system, however, I've managed to get my hands on a Marvel 4 ECU so have no need for this. This ECU is for a 1098 with a full system and air filter. It's in good condition and ran without issue before I took it off the bike. Someone has written 1098R on the ECU, however, that's not the case and it is not for a 1098R. I bought this for £225 but looking for £185 including postage.
