2006 model, the exhaust is very sleek, i see no bread box!
There are a couple of ways to determine the year of your bike. One is via the VIN. The tenth digit denotes the year.Will check fans soon, Merc07 thinks i have the 5SM.
But, since you need to determine what ECU you have, 1.6M or 5SM, and that changed between MY 06 and MY 07, you can look at the ECU to tell. It is noted as the Motor Control Unit. For the 1.6M, there is only one electrical connection plug on the side o f the unit and the unit is on top of the engine under the fuel tank. For the 5SM, the Motor Control Unit is on the back side of the engine below the throttle bodies and it has two electrical connectors with BRIGHT RED latches.
