I was on a motorcycle trip to banff, ab. About 50k north of crowsnest pass, ab on gravel highway 40 I had a bit of a wobble that moved me into the soft gravel shoulder. It was safer to ride into the ditch so that is what I did. Just after coming up on the other side of the ditch the front fork broke on a small bump launching me through the air, and toppling the bike behind me. I was probably going about 40mph at the time of the failure. I dislocated my shoulder and tore several tendons in the incident. The motorcycle is a bmw f650 gs dakar. The failure is very similar to... Case: ivoq- 2002 bmw motorcycle case number: 28597. *Tr
A hairline crack in the fuel pump/filter assembly "cap" on top of the tank which allows fuel to leak out of the tank and pool under the seat creating a fire/explosion hazard. This is the same problem referred to in nhtsa campaign id number : 04v236000 regarding the cs model. Parts are available, but dealer will only perform at owners cost because there was no recall issued specifically for the gs model. *Jb
The ignition switch on a 2003 f650 gs bmw motorcycle is located on the steering head. This switch has a loom of four electrical wires that connect to it and goes to relays that operate the functions of the electrical system. One of the wires, a green one, is a 16 gauge copper wire with 19 strands. This wire is the link for all the electric current to operate the motorcycle. When this wire fails, the engine dies, the lights go off, and all the power to the motorcycle is lost. The wire loom containing this green...
Read the full complaint
16 gauge wire is designed to fail because every time the handlebars on the bike are moved, the wire loom flexes and over time this green wire becomes brittle, due to molecular changes in the copper, and breaks. This will happen on every bike that has this 16 gauge 19 strand wire, as this wire is not engineered to be flexed constantly. In fact, this wire will break by holding it stationary in one hand, by a connector, and bending it with the other hand. It will break within 30 up and down bends and this is the wire that transmits all the power to operate the motorcycle. My motorcycle is a 2003 model that was put into use at 06/16/2003 with 6230 miles. That is when I lost power making a left hand turn, the motor stopped and the lights went out. Luckily it was daytime and no traffic. If this failure had occurred on a dark country road or in heavy traffic the outcome could have been much different. I repaired the harness by replacing all four wires with a 16 gauge 62 strand copper wire that is engineered to flex. I have the old wires and pictures of the wire loom before I repaired it. I will furnish you with the original wires and pictures upon request. *Nm
Dt*: the contact stated the motorcycle's front and rear master cylinder failed at 25,000 miles. The motorcycle is not experiencing the problem now. When this fails the front and rear master cylinders need to be rebuilt or replaced. The contact tried on numerous occasions to contact the manufacturer without success. Updated 4/11/2006 - *nm
The electrical system on my 2003 bmw 650 cs has continually broken down--stalled (often times while the bike is actually in motion). I have brought the bike to honda of hollywood over three times for this problem and each time, they have been unable to find the locus of the problem. The problem is intermittent and it generally does not happen when the bike is with the dealer, so they cannot fix it.*Ak
