Hey all, I've got a 2019 CB650R with the A2 restriction. However, in a couple of months I plan to complete my full Category A licence allowing me to remove the restriction completely! Does anyone have any experience with derestricting this model? I've done some research and can see that the bike is restricted at the air intake and via the ECU.

I've been quoted £400+ by my local dealer to get it put back to full power but they gave me the stock air trumpets with the bike when I bought it so it can't be that difficult to refit the stock ones surely? The only hurdle would be the ECU, so how easy is it to flash it? Would a Power Commander override the A2 ECU map, could you fiddle around with the O2 sensor to trick the ECU into giving full power?

I've seen some Aussies talk about removing their LAMS restriction on the forum but it seems that their rules are different so I don't know if they'd apply on the EU bikes.

Many thanks in advance.

Hi guys,
Another 2019+ 650 restriction thread.
Recently got myself the 2019 CB650R and love it but am looking longer term to remove the LAMS restriction in Australia.
I am on my full license and went with the 650 because of it's looks, reliability and mid range size so hope to have this for the next 5 years at least.
Have managed to locate some OEM unrestricted funnels but the ECU is what is my major hurdle.
Appreciate that in the UK a dealer can update the software, I'm not looking for a performance beast so I am happy with the stock Honda software.
Do they only offer this to UK bikes? I'd love the peace of mind of having official Honda ECU software so has anybody been through the process of derestricting an A2 bike?
Could you just mail them an Australian ECU?
Very new to this kind of thing so happy to have advice thrown my way and opinions!
Thanks
V

Hi there,

I’m in the same situation. Have you gotten any further? Is it only the air trumpets and a ECU remap?

Many thanks

Hi,
I have a 2015 cb650f lams model. I purchased both the non restricted funnels and dynojet fuel commander from the US.
Downloaded all available maps and with some fine adjustments have the bike running pretty good. Mid range is good with a decent enough top end to make overtaking a breeze. Most days consist of a 120km round trip commute. As it is a naked bike I am not too concerned about top speed but would easily break the legal speed limit ;-)

I had mine done today.. full Akro exhaust,DNA filter, woolich harness and dyno tuned..i ground out the restricted funnels myself before getting it all done. Ended up with 88rwhp and is a completely different bike to ride. I actually enjoy it now. Was about $2500 total..

The replacement of the air trumpets and an ECU remap cost only 54 EUR at my Honda dealer.

In Germany, the whole thing has to be approved by the TÜV (Association for Technical Inspection) and additionally registered in the vehicle license by the vehicle registration office (?). :wideyed:

If you can find the intake funnels in Australia they are $100 by themselves, and I had a custom tune on the bike not just a flash. It’s illegal to do any of it in Australia as far as I know..

I bought a 2019 cbr 650r with the funnels already bored out but couldn't get any info on wether the ecu was flashed or not. I've herd horror stories about ecu not being flashed properly etc. After speaking to a local race mechanic, I'm taking it in for a dynotune - mapped against race bikes and a set of Metzler Sportec M9 this week. Will update the post with the results.

I’d say if your intake funnels have been opened up it’s also had something done to the ecu, maybe a full tune or just a generic map that some sell..either way you would easily be able to tell if it’s derestricted as the difference is night and day!
Im in NSW and traveled to Sydney to have it done..I actually like the bike now although with the Akro exhaust it’s probably a bit louder than I wanted which is unusual for me to say..

Hi all
Took my cb650r to a bloke called Dave at dynobike( melbourne) he really knows his stuff. Had the trumpets fit,ecu flashed and aftermarket air filters. The bike is an absolute dream to ride now. More than enough power for what i need. The power is just above double the amount of the lams version.
Very happy with it.

I’ve heard mixed things about this guy..unless you had a really low output initially more than double seems a bit of a stretch..

A cheaper alternative is to run with stock filter , fuel commander and downloaded map. Easy to tweak yourself. More useable power, smooth throttle response. About $500 .
