2009 BMW R 1200 Rt

TECHNICIAN FOUND THAT THE ENGINE DOES NOT RESPOND TO THROTTLE INPUTS. DISCOVERED LEFT AND RIGHT THROTTLE BODY REQUIRE REPLACEMENT DUE TO CABLE CAMS ARE BROKEN. BOUGHT THIS BIKE FOR PARTS. CHOSE TO FIX IT UP GIVEN LOW MILEAGE. LOOKS LIKE PLASTIC CAM FRACTURES FREQUENTLY. LUCKY I FOUND OUT BEFORE I TRIED RIDING IT. NEWER MODELS BY MANUFACTURER AND AFTERMARKET PARTS OFFER METAL CAM. EVEN MY KIDS CAR SEATS NEED TO BE REPLACED AFTER 10 YEARS BECAUSE OF “PLASTICS FATIGUE/FAILURE”.

On 06-19-2023 i was North bound I275 north of 8 mile about 715pm. I was in the left lane going about 68 mph. All of a sudden my It felt like my throttle cable broke, when I twisted it there was no motor response forward and backward, but my motor was red lining against the Rev limiter, so I pulled in the clutch and it did not slow down at all. Actually I sped up to over 100 mph, thankfully there was noone in front of me, I steadily pulled on the front brake and stepped on the back brake until I came to a stop. The length I went was at least 1 1/2- 2 miles from when I thought the cable broke till I got it stopped. I had it towed to southeast bmw in Plymouth, MI. It's still in the shop as of July 31,2023. So I don't know what exactly went wrong yet. They are waiting on a part and said the throttle cable didn't break. My question is why did I continue to go faster while the clutch was in. Besides what ever went wrong on the bike and heavier pants, myself and the bike were not harmed.

The OEM plastic 90° quick discount fitting on top of the fuel pump started spraying fuel. I started smelling fuel on the interstate highway 10 and by the time I could pull over safely off the interstate I was covered with fuel. The fuel was running down on the hot exhaust pipe’s on the front left side of the motorcycle and spraying all over my face and legs. I could have been set on fire and burnt to death because of where the fuel was spraying from. This also could have cost the lives of the people on the interstate had i burst into flames and lost control of the motorcycle. When I called the BMW dealership in Tucson AZ the service tech told me that they had a medal aftermarket 90° fitting that would fix my problem. I replaced the fitting and the fuel leak was fixed. This motorcycle fuel pump was replaced 07/01/2014 at mileage 12,482 because of a fuel leak recall. I’m filling this report because this fitting fail happened without warning 15,700 miles after the fuel flange recall. This must be a common problem for the service tech to know over the phone the fox and have a aftermarket medal part that fixed the fuel leak. The location of this potential leak makes it extremely dangerous hazard.

2009 BMW R1200RT MOTORCYCLE REAR BEARING FAILURE THAT LED TO A FINAL DRIVE FAILURE. At highway speed, heard clicking noise from rear of bike. While parked on center stand and spinning rear wheel, heard a terrible grinding sound. Who knows what would have happened had I not exited when I did. This left me stranded, requiring a tow; repair took two days and was over $3,000.

2009 BMW R1200RT MOTORCYCLE WITH 50,482 MILES. THROTTLE CABLE PULLEYS/CAMS BOTH SHOWING SIGNS OF MULTIPLE CRACKS. ONCE THEY CRACK COMPLETELY, THE MOTORCYCLE BECOMES UNRIDEABLE AND MUST BE TOWED. THROTTLE NO LONGER FUNCTIONS AND MOTORCYCLE JUST RETURNS TO IDLE. MUST EITHER REPLACE ENTIRE THROTTLE BODY OR REMOVE AND REPLACE EXISTING PLASTIC CAMS WHICH HAVE FAILED.

THE THROTTLE BODIES ON THIS MOTORCYCLE ARE CABLE-ACTUATED, WITH PLASTIC PULLEYS MOLDED ONTO THE THROTTLE SPINDLES. THESE PLASTIC PULLEYS WERE SEVERELY CRACKED AND I HAVE REPLACED THEM (I STILL HAVE THE OLD PARTS). I'M AWARE OF NUMEROUS BMW MOTORCYCLES OF THIS VINTAGE THAT HAVE DEVELOPED CRACKS IN THE THROTTLE PULLEYS. I DISCOVERED MY PROBLEM VIA INSPECTION IN MY GARAGE, BUT I'M CURRENTLY AWARE OF TWO OTHER OWNERS FOR WHOM THE PULLEYS DETACHED FROM THE SPINDLES WHILE RIDING, CAUSING A SUDDEN LOSS OF ENGINE POWER. THIS PROBLEM HAS ALSO MANIFESTED ON OTHER BMW MOTORCYCLES THAT USE THE SAME ENGINE (E.G. THE R1200GS).
