Great oil filler plug
I just purchased a slightly used 2016 BMW S1000R ( 8000 miles ) and the original filler plug leaked/dribbled some down the engine case. This new Wunderlich oil filler plug is all metal and top notch. No leaks , no dribbles and it's quite handsome on the bike. BTW: My old plastic plug's threads were starting to deteriorate around the last thread on the plug and one part of a plastic thread was hanging loose when I removed it to change them out!
