Hello Guys,

In France, government forces Motorbike manufacturers to limit the horsepower at 106 instead of 115.

In racing circuit usage for example, we found that to get back the full power of the FZ09 (MT09 in France) we need to connect a blue wire located under the seat to the battery ground and then manipulate the meter to a proper menu.

Some of us from Forum Yamaha MT-09 France - Portail french forum were wondering if one of you could maybe take a similar picture than this one to compare how are configured MT09 wires that are always in full power



You can find this just under the seat attached close to the fuel Tank




Thanks for your help guys, you will help us in finding how yamaha change configuration between French and others FZ09

Cheers !

Speedcat !

Hell even ours here in the states are top speed limited to just 132mph in both 5th and 6th gears. Hopefully we can all get them to full power/speed with more experimentation.

Yep us too, We have both speed limit at 132mph and HP limit at 106. But to unlimit HP from 106 to 115 , we need this small trick and see what you have in the US under the seat.
unlimiting top speed will be a little bit more difficult I guess...
Cheers !

I can't figure out what he is trying to do. The FZ-09 only has 105 to 106 hp. There is no more. Yamaha measured that 114 hp at the crank...so........????

In France, they are limited to 106 hp at the crank. So 9 less hp than here. If i`m right, they got the same rule for every bike, even the big SS.

Seems the American FZ has an extra wire, the yellow with a blue stripe at the lower left(rear).

Thanks a lot for this photo and yes you have 1 more wire.
If you unplug it, what do you see? because in France we see that the light blue wire is plugged to nothing…
Maybe your extra wire is linked to the battery ground and the both wires on the left are plugged together?


Yes, In france we are limited to 106hp at crank which is even lower at the wheel...

We're still working on mapping the exact pin-out of the ECU connector (the service manual only shows so much). It would be interesting to see the map from an MT to know if it's the same as an FZ. The first inclination would be that the throttle maps are restricted, similar to what is done in B mode. But, the wire trick seems to indicate otherwise. The Euro bikes have ABS and an immobilizer, so there are other differences we have to account for.
