    So far all’s good
    By  Jim,  a  Verified Buyer  from  California  on  April 28, 2024
    This is the first time using this oil on my KTM500. Just rode 61 miles of rocky roads and hills in San Diego County. Had a few tip overs but the bike is running great. I wish the local shops would carry the oil like cycle gear. I guess I’ll just order extra oil for my stock and figure the shipping is the cost of my time and gas to go get the oil.
    Bottom Line
    Yes, I would recommend this to a friend.
