It is perfect for motorcycles that rev up the speeds... excellent performance and engine sound.
Also, for those who are concerned about oil temperatures, for the 15w it ranges from -5 degrees Celsius to 50 degrees Celsius.
In motorcycles that operate within a temperature range of 88 to 116 degrees, it has better lubrication response compared to a 10w 40.

In a Honda Innova 2008 scooter.
I used Honda, Motul, Maxima oils and now Bel Ray. Flawless in every aspect. From the engine performance, smooth transmission, to the sound of the bell. I am very satisfied. I highly recommend it without hesitation.

I have it on my BMW R1150GS for about 600km. I can't say that I was impressed by the feeling and sound of the engine compared to other oils I have used. Okay, but... I will see it over time

I put the oil in a BMW r1200gs and because I was satisfied with the engine performance, I will put it again.

I wear them on a Yamaha Fazer 600 model 04. Indeed, much better engine performance and a much smoother gearbox compared to the Motul ones I used to put. I recommend them

The best thing there is for an Africa 750... the difference was immediately apparent... the comments helped me a lot

I didn't notice any difference from other oils. We're talking about papi crypton x. Oil change every 1000 kilometers. The gears didn't shift smoother, and at the 1000 kilometer mark, its performance doesn't inspire confidence for more kilometers.

Much better than the Motul I used to use. Better performance from idle to high revs. Noticeable difference in the gearbox. Worth it. Xrv 750 rd0A

Tested on triumph explorer 1200. Smoother operation compared to the previous (triumph) and better engine sound. I cannot comment on durability and long-term performance as the motorcycle was sold, but the initial impression was very positive.

In the 2008 v-strom 650, no other oil has been added since I bought it and the gearbox is always smooth, unlike others that I hear about having hard gear shifts and gears not engaging!!

Very good oil, I am very satisfied. The gears shift smoothly and you can hear the engine working correctly! For Suzuki V-storm DL650

I have been using Motul 5100 15 50 for years and it really softened the gearbox. Overall, I was satisfied, even though the Kawasaki z750 had some issues with shifting. I read the comments and decided to try Belray exp 15 50...
I was amazed, the gearbox is completely silent now, it became butter... I never expected an oil to make such a difference in softening. And if it does this to a Kawasaki gearbox, imagine what it does to the rest...
It works better both at idle and at high revs... And yet, the oil can make such a big difference...
I will never change it, unless the price goes up or they compromise its quality (as a friend mentioned).
Personally, for me, it is much better than the previous one, and by far!

I put the oil in my GSR600, until now I used CASTROL 10W-40, the differences are not big, the gears go in a little better and the engine became a little quieter. Of course, it's the first day and I only did 60 km, I will wait to see if there is a bigger improvement in more kilometers.

In fz6 s2 600 2007 by motul that was banging like it had stones inside, I read on a forum about bel ray and I was proven right, its gearbox operation changed completely, a big difference, very smooth shifts compared to before with motul.. from now on, only bel ray unless they ruin it in the future and we look for something else. Highly recommended!!

The oil is not available. I was using Motul 10-40 and decided to try this one on my 2008 Vstrom 650. The best oil. I feel like the engine runs smoother. Especially in the summer when I take long trips with high temperatures, on the highway and with luggage, it doesn't burn a drop of oil. Whereas with Motul, it would consume 100 grams. Also, the gears shift more smoothly, which means the transmission is properly lubricated. Excellent oil. I've been using only this for 2 years now.

After 4 years of use on a kaze-r 115cm, I have to say that the oil is truly top-notch in its category. The engine works flawlessly even today, having covered 50,000km WITHOUT any repairs, of course, except for the change at 1500km or every 6 months..... because you take care to have
