I use Mobil 1 in both my Harley and 2016 Super Tenere. The clatter noise from my Super Tenere (5500 miles) was troublesome to say the least. I just did not enjoy riding it due to the clattering noise. I had remorse about buying the ST and thought about selling it. Someone had written that is...
On my 2016 ES, I have the Yamaha Tall windshield with the Yamaha side wind deflectors, and the Madstad adjustable bracket. This combo works well for me. The side wind deflectors are necessary in my opinion.
