  • I put it in my bike, a KLE 500, for the second time and it’s just fine, even on summer trips I had no problems with the gearbox like I did with the previous oil I used for years. I changed it at 5000 km and I can say it could have lasted even longer

  • Very bad oil. It was tested in an xt600e with a perfect engine. The bike previously ran with motul 7100 20w50 and after 4000 km the oil was still at the same level and in quite good condition. I put this one in along with a filter change, that is, 3.7 liters of oil according to the manufacturer, and it was full three days ago. And today I added 800ml. Where it went, I really don't know, I am left astonished. The bike ran much better with motul and tomorrow I will go throw it out and put motul back in. Really a waste of money.

  • Very good oil. I use it on my Honda SupraX 125cc. I used to use the genuine Honda oil, but since I first used Bel-Ray, I will never go back to Honda.
