Hello, I'm complete noob on this topic. So I would like to ask whether it's possible to derestrict the 35kw EU version of this bike. My riding school instructor recommended that I derestrict the bike. But when I asked about it at the dealership that I bought the bike at, they said they are not able to do it ( I very much doubt that, but they wouldn't give in, so whatever ).

Some places said that you can achieve this by flashing the ECU, others that you need to do a manual derestriction as well.

Does anyone has any experience with this? Or even better yet if you are in EU know a shop that would be willing to do it?

Thank you in advance.

You have the mandatory open license and want to derestrict?

Mine is restricted to 35kw as well - my yamaha dealer told me they will destrict when I get a license for 35kw+.
So surely it's possible - I also considered destriciting it before it's meant to be done but not sure about insurance.

Well thats the thing I don't think anything would change. As I said when instructor told me this. I had a look at our country's version of craigslist and found a sea of bikes that say 35kw in the papers but actually are fully open. Even the dude at yamaha said that yes this was a common practice to have it let's say illegally open to full power. I even found CBR1000RR Fireblade with 25kw written in the papers.... So I think nothing would change in that aspect.

I have the A2 license which limits me to 35kw and I would like to open my R7 to full power.

You'd need to check a few things. If they use the same restrictions as they do in Australia there's normally 4:
1. Intake runners are smaller diameter.
2. Throttle plate doesn't allow TBs to open 100%.
3. The ECU mapping is different.
4. The displacement of the engine is smaller. (655 vs 689)

The intake runners you can cut out to the proper size with a craft knife.
The throttle plate can be purchased or can be filed down to open correctly.
The mapping would need to be updated by either someone with the correct tools or a professional.
The capacity is something that you can't change easily, but with enough money can be fixed.

No it's not the Lams version of the bike this one should be 689cc even if restricted. That's why I hoped it would just be an ECU flash and that would be it. Did you unrestrict your R7?

What I know from restricted MT, XSR or Tracer, the 35 kW version runs quite fine, only at higher speeds you will feel the difference and lack of power. Everything from city limits to 120 km/h is same same, and above will be a bit more slow. So in my opinion, there is no need to derestrict and living in fear to ride a bike with no driving license. I do not know what the typical fines are, in your country.

My approach, written from age and some experience, ride this bike as it is. Avoid too many additional parts as useless bling-bling or too personal builds. Sell that bike after two years with a ridiculous little loss and go for an unrestricted new one, or something different. And just use these two years of restricted riding to learn as much as possible. Ride a lot, spent time to collect experience and go for a guided training from time to time.

Ahh good good, in that case a flash is probably enough but I'm not too sure.
I've done some work with them, the throttle plate is easy to fix, you can do it yourself with some filing or you can buy a new one for about $30 AUD, the intake runners can be opened up or you can replace them (oem or just go for the Hord option), the fuel maps actually look the same as the 689 but obviously in the stock maps are a bit average and you only use up to 66% throttle anyway.

Does the mt07 throttle plate fit the R7? For part of the de restriction

Yes, as do the intake runners if your interested in doing them too.

Thanks really appreciate it

I did the runners and air filter today and the throttle plate is still on the way, what’s the chances I could just undone those 2 screws and loosen that top bolt to slide it off and install the new one?

Pretty much how it's done. Loosen the throttle cables, undo the 2 screws, put the new one in, tighten the new screws in, re-attach throttle cables.

There's a decent run through the process here:
