    A must for your Vtwin
    By  Sammy,  a  Verified Buyer  from  Orlando FL  on  February 26, 2018
    If you have a Harley this oil is a must. It removes all valve train noise, reduces engine temps and Amsoil's the only oil manufacture to torture test the hell out of your bike to prove it still protects under the harvest conditions. Stop being cheap and spend the dough to make you bike last the longest.
    Bottom Line
    Yes, I would recommend this to a friend.

    Yes, I would recommend this to a friend.
