I was wondering if it is possible to get a lighter flywheel for the 2013+ 636's. A friend of mine suggested I add it to the long list of things I am already doing to my 636. He was not sure if it is possible with our engine and neither am I (he is a Ducati guy). Just curious if anyone else thinks its even worth doing and/or has done it? How light is too light? Where they bought it from and the difficulty level of installation.
