Hi guys,

I have XSR700 35KW(A2). Can I unlock it by different way than replace electronic control unit?

Thanks.

Wouldnt fitting a power commander work to change the map of the bike?
It should be electronicaly restricted only....but some manufacturers lock their maps
Im not sure on motorbikes but i know this to be true on cars as i had my vw mapped.

You may need a different ecu for upgrade but i should imagine it would just be mapped.

Yes. It is just an electronic limitation. You just let it reprogram to unthrottle the bike. But you must do this at an authorized yamaha dealer since your registration must be modified accordingly. Otherwise you get into trouble in case of any accident or insurance claim.

That would be great if Australian restricted bikes weren't also 655 instead of 689. So it can only be a custom map.

I would bet with a good mapper who has knowledge of the bike a significant improvement of power could be gained with this bike. But id wait untill your warranty ends before you play with the mapping and like i say the map may even be locked?

Hi Dado,

You should watch this movie. This should help you to unlock the bike. This YouTuber has FZ07 but it is the same engine so the same procedure should work for XSR700.

Thank you guys for your answering.
Replace throttle plate, pop in DNA hi flow filter, modify filter inlet to allow more flow, dremel out stacks and then get it re-tuned. Search YouTube for "derestrict mt-07". There's plenty of info.

these are electronically restricted? i thought they were just done by the throttle body like the mt07??
XSR was EUR4 only, in difference to MT-07, which was available as an earlier EUR3 as well. So it should be restricted by electronics and there can be an additional mechanical reducer as well.

I just recently bought an xsr700 16 plate. To find it has a restrictor kit. I rang the garage and they said it had a throttle plate restriction. To my amazement not the ecu restrictor.

...I am just a forum's user, so...

You know your XSR best and can see in the papers and on the frame, what it is:

Yamaha OEM 35 kW built, then it will be two manifolds, a new map and finally an adhesive or sticker on the frame to change,

Other third party 35 kW restriction will be something like a piggyback electronic and I assume two restrictive washers for the intake. And some paper or documents which show what is installed.
