BMW RnineT - Remove Battery & Air Filter - How To - R9T By Fritz Washabaugh 

You should connect the positive cable first then the negative. Less chance of arcing the screwdriver to ground as you tightened the positive lead if the negative is not connected.

It never ceases to amaze me that most all marques force us to dismantle halve the bike to replace the air filter

Just bought a 2014 R9T today. Battery was weak, so I know I have to replace it. Thank you!!

Fritz, Big mistake... remove the negative terminal first and replace it last!! If your negative is attached and you drop a tool across the positive terminal and ANYTHING METAL on your bike, you will understand and never make that mistake again. The blinding flash will be memorable.

Good instructions, very clear and thorough. Well done.

Every time I think of going back to BMW I watch a video of somebody spending a day changing the air filter and I remember doing the same with an R1200C. Wonderful bike. But I got tired of removing the tank to do anything other than putting air in the tires.

Very helpful tutorial. Thanks

Thank you for the tutorial...What a pain in the arse for a battery replacement, I'll make an appointment now at the dealership to fix what I broke or lost.

Thank you for your informative video. I have been running a 1984 R100RT for 30 years and it is uber easy to work on etc. I added a 2017 R9T to the garage and then started looking at how to work on it. They do not even give you a manual that shows you fluid amounts for transmission or drive line or where to locate rear drive fill hole! I had to Google it to figure it out. And as for general upkeep work like battery and air filter... SURPRISE! Who was the sadistic engineer who came up with this layout! Nothing is easy. I can see why some people put on pod filters right at the intake of the injectors. And the CAN BUS electrical system is just a mystery to me. I love the bike and how it performs but I have been letting dealer do everything during warranty and probably will continue to do so afterwards as well. I have yet to look to see how or even if one can access battery to jump it if need be given it is buried away.

Thanks.

Thank you very much. My racer is 3 years old. Today it failed to start. looks like the weak battery was the issue.

Nice video

The tank does not have to be completely removed, just unscrew the mounts and raise it by placing some sort of emphasis. There will be much less work and there will be no risk of breaking the hoses and wires.)

Hey Fritz TJ - awesome video. Just another one that helped me a lot ! Can I interest you into making one with general & useful maintenance on the R nine T?

I think of my Triumph T120 as being so much harder to work on than earlier models, but this is another level of complication altogether.

Thanks for the great video! One question. I am having a pain of a time trying to disconnect the diagnostic cables without damaging them. I have a 2015, and that year model has two plugs that go from the wiring harness to the fuel pump. Any tricks to getting these disconnected safely?

Thanks for the video! Had to remove tank and replace my battery and fuel quick disconnect. Did you have to map the ecu when you put everything back?

Hi Fritz, Nice video. Can you tell us what tool roll you are using? It looks really convenient. Thanks!

great video btw what torx key size did you use to remove the front screw of the tank?

I loosen the rear bolt for the tank and then remove the front bolts. Tip the tank back and put a prop under it. Then you can reach under the front to remove the wires and hoses without any danger of the tank falling. Take the prop from underneath, lower the tank and remove the rear bolt. Then lift the tank with both hands. Never any danger of losing the tank.

I want to add a trickle charger like you have and was going to put the positive on the red bolted down terminal but what is the best place to earth it?

Just the name gets a thumbs up

Can an upgraded battery like Ytx16bs with dimensions of 150x87x161 mm fits in the battery compartment?

hello, what mirrors and grips u using ? thanks in advance

thanks for this great video... but just one ask, why did you put on the bike a carpet, you thought the bike was freezing ? :p :p

Do you have to remove the fuel from the tank to disconnect the lines?

What is the benefit of removing the carbon canister? I have heard a few people doing it.

wow thats a lot of work for replacing a battery, by the way, how long does the battery last before it dies down?

You don't need to remove the fuel tank completely off. All you need to do is prop the back of the tank with the wood.

You have to take the tank off to change the battery? Crazy.

Gee, and I thought my Tuono was a pain! You have to remove the tank to get to the battery? Connect trickle charger lines, etc? Even to jump start it? Wow!

what brand of battery did you used?

Simple then

all of that for just a goddam battery, but still i love bmw rnine t

Hands down the worst bike I’ve had to acces the battery

Worst design ever for battery access...

Removing the tank to change the battery is one of the stupidiest thing in the world. How come BMW design their bike like that?? Make sure less people maintains their own bike I guess.

Such an unnecessarily pain in the ass process. It could have been so much easier. BMW engineers must have intentionally worked out a way to make battery and air box maintenance more difficult. Why mount a bunch of decorative crap in the way and make things so complicated when battery and air filter maintenance is so routine?
