I've got a 2018 R NineT Classic and have just placed an order for a set of Remus headers to go with my Akrapovic single silencer. As many (not all) would agree, when modifying the intake and or exhaust, something should really be done to assist fueling with the more free-flowing air/exhaust, especially given the Euro 4 bikes tend to run on the lean side due to emissions.

I've done a fair bit of reading across this and other forums regarding booster plugs, AF-Xied modules, Re-Maps, and piggyback modules (AKA: PC5, RB, etc) and weighed up what would work best for me. Given I'm still well within my warranty period, I quickly ruled out the re-map and more complex piggyback modules, which left me with a Booster Plug or AF-Xied. After even more reading and weighing up both camps, I was leaning towards the AF-Xied side as I believe (from what I've read only) that the BP works initially, but is slowly adjusted out of the equation by the factory ECU. So I was set on the AF-Xied. Given I'd need a twin AF-Xied module for our boxer, the price for such a simple module was more than I was willing to pay. So after a little more searching around, I came across what I ended up purchasing, the Rapid Bike EASY!

The Rapid Bike Easy essentially works the exact same way the AF-Xied does, but in a much neater package and at around half the price. It's a simple plug-and-play device (easy to remove in warranty situations), no cutting, waterproof connectors, and an easy-to-follow guide stating the optimal settings for your bike.

I've yet to use the module as I'm still waiting on the headers to arrive, but will report back once it is all done.

Below are a few photos of the unit. Also note that the same module can be used on a number of other BMW models, including all 1200 series boxers through to 09-2018 S1000RR's.

If anyone's used one of these before, I'd be grateful if you'd chime in and let me know your opinions, findings, tips, etc. Or if people have used similar units that have any useful info, that would be great too.

Thanks

Great information and advice in this thread

I bought myself a Rapidbike Easy for my 2016 Classic, and I found out it wasn't shipped with the correct cable

so I ended up with a single sided BMW connector (for K-series)... I imagine this will only get me half the result I'll be looking for since only one cylinder will be connected to the magic-box.

Does anybody know where I would be able to get just the cable for the R-NineT (I live in Europe, Spain, the original provider does not have any other cables)? Would it hurt if I run the bike for a prolonged time using the set-up with a single cylinder connected?

Tezpigeon, I wouldn't recommend running your bike with that unit. They are model specific and the correct one will have two cables coming from it. There are two dials as you may have read, one for the model of bike and the other for fuel richness. Don't want this all ending in tears, send it back and get the correct unit.

I was of the understanding that the actual unit is one that is used for just about any bike. The only thing that will make it bike-specific is the cable that connects it to the sensors on the bike. Mine was sent with a (separate) cable for a K-series machines and has a single O2-sensor connection as opposed to a double one, which I understand from this thread is actually the one to have.
I will not be riding my bike, or at least not with the little computer connected, until I have the right cable.

I've spoken to the manufacturer of the Rapidbike Easy (Dimsport in Italy), and they confirmed that the electronics box is generic, so can be used for all bikes. You just need to make sure the first dial is set correctly for the type of bike. The only thing that is bike specific, is the connecting cable for the Lambda-sensors.

Thanks Tezpigeon, good to know.
Once I am ready for the Rapid Evo, I can tansfer the RBE to my G650GS using a different cable.

Just make sure you check out if the RBE is capable to handle the G650. If the cable happens to be the same as that for the F650, I have one lying around currently (it's up for sale in the Marketplace Forum).

Ok, I see your for sale thread.
That is for the F650GS twin cylinder.
BMW confusing people with naming the twin the same as the old F650GS single

I couldn't find the G650 on the Dimsport site either, so I wasn't sure if the cable would be the same. Even-though it's a cable for a twin (F an K), it only has one sensor connector, so perhaps it is the same cable... (unlike the one required for the R, which has 2).

I've been happily running with the Rapid Easybike for a couple of months now. Unfortunately though, I've now run into some regulations issues

my CO exhaust gas levels are out of limits... I've used the recommended settings (5 and +3), should I reduce the AFR to 0 to get the CO levels down again?

Sorted

with the recommended “+3” the engine was running ‘too rich’ for EuroWhichever regulations. Turning the AFM to “0” kept all CO levels within EU limitations

and the bike passed her check with flying colours

.

I’m thinking about running it on “+2” i.s.o. “+3”, does anybody have any experience or suggestions for that?

+0 means the module isn't doing anything. Maybe set it to +0 for inspections, and then back to +3 when you're ready to ride around again?

Exactly, that is what I figured as well. I would not recommend keeping it on "0" too long, as I had the engine stop on me during the ride back home from the inspection while slowing down... I'm not sure if it was mishandling on my side (not possible hahaha

) or the engine running slightly too lean due to the open air filters in stead of the airbox. Once the weather allows for more riding again I will certainly investigate and try out more settings.

I have read this thread but still unsure....for me, I have a 2020 MY /5, so it is a euro4 ecu. Is the RP Easy suitable/workable/worth it for this model year, or is it really best for pre2017? The bike is also on stock pipes with cat and stock end can.

According to their website it's suitable for all R-NineT's MY 2014-20.
