What kind of transmission does a BMW motorcycle have?
This is a “slider” or shifter plate found in a /2, /5, /6 and /7 BMW motorcycle transmission. It may have other names, but the name is not important. This part drives the output shaft and selects one of two gears, or neutral. The outer groove that the shift forks ride in has been machined. They have a center.
Is the BMW 6 transmission hard to find?
This 1974 BMW motorcycle /6 transmission was known to be hard to find neutral, and that shows up in this test. When riding that model bike, it is far easier to shift to neutral while rolling the last 10 feet before the full stop. This transmission passed every test.
What’s the rule of thumb for BMW transmission?
The rule of thumb is to pinch as much of the fuzz as possible between two fingers and rub them together. If you can easily feel the fuzz as fine sand, that is bad. If the fuzz feels smooth, then that is good. Well, maybe not good, but as good as it gets, and the bearings aren’t coming apart soon. Record your findings in your logbook.
How often does a BMW transmission need repair?
It is typical for a BMW transmission, using natural petroleum hypoid gear oil, to need repair in 50-75 k miles. Most make it to 50 k, and most are opened up by 75 k miles. Yes, you can find the occasional transmission that violates these numbers, but I am giving the average.
