2008 BMW R1200GS motor starter replacement. The starter was giving intermittent problems. I purchased an aftermarket starter from Carpi Moto (https://www.carpimoto.com/en-US/). They carry WAI products. Installations was quite straight forward and the result has been good! Hope this helps others with similar issues.
It’s specific on the BMW R1200GS but it should be similar to other bikes as well.
