Benelli 491 98r product really ok I thought it would be without revelation but it surprised me after pouring oil it turned out that it dampens the sound of springs very well and I was convinced that this type has the same type of shock absorption itself has improved quite a lot small bumps picks quite calmly large ones are no longer terrible for me on a long journey my hands rest so I encourage you to buy.

Sylwester

Suzuki DL1000 V-Strom 2006. As for the oil, it is difficult to comment for now, because I have not yet ridden after the change. The big plus of this oil is the capacity of the package. A total of about 1.1 liters goes into the lags of my motorcycle, so I didn't have to buy liter packs. The oil itself could be tinted in some interesting color, although it does not add much it is more pleasant to change.

I own a 2003 yamahe dt 50. Castrol MTX oil, which I bought works perfectly, the clutch works perfectly and the gears enter smoothly and without rasping. I was able to pour the oil into the gearbox without any problems, and the application was much easier thanks to a specially shaped cap with a special spout.
