First day on the v strom 2005..EXCELLENT!!
Factory engine, and buttery gears..
I will come back in a month from now to see if it consumes oil..
Tip: Fill it up to the line, take a 10-kilometer ride, and leave the bike until the next one.. Then refill…⭐️
One month update.. the engine starts to knock!!
Very good oil, it is not 100% synthetic in 10w-40 viscosity but semi-synthetic. It is an improved version of Bel Ray EXP which is also semi-synthetic.
Only the ones that say Works on the bottle (10w-50 + 10w-60) are 100% synthetic, which are an improved version of Bel Ray EXS which is also 100% synthetic.
It changes the engine's performance and sound, the gearbox has a noticeable improvement compared to Motul 7100 (maybe because it is 100% synthetic). Because I have tried many oils for 27 years on all types of motorcycles (SS1000, Supermotard, ON-OFF), don't just consider the gearbox's performance when choosing your favorite oil... and think that this one is better than the other...
How the gears engage has a lot to do with whether the chain is properly tensioned/clean and well lubricated.
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.
In Honda GTR150, I tried the Motul 7100 10w-30 and they didn't work well... the gearbox was too hard and the engine was noisy.
My friend recommended the Bel Ray Thumper 10w-40 and how good of an oil it is, so I switched to it from Motul 7100.
The gearbox is now like a joystick and the engine sound is smooth.
Unfortunately, it doesn't have viscosity 10w-30 as recommended in the Honda manual, but 10w-40, not that it makes a difference... anyway, the cold start is a 10 in both.
I tried the Bel-Ray Thumper 15W-50 on a Zontes 310 T1 and the bike's temperature increased more easily, the engine sound became deeper, and the gearbox had a harder time shifting gears. I replaced them with the Motul 7100 10w-40 and the bike calmed down.
I put them on a Suzuki GSR 600. I had the Motul 7100 and after 3500km I switched to these Bel Ray ones. Okay, the gearbox went into silent operation. As for the engine, I will come back when I do some kilometers to see any potential differences. I highly recommend them
I have been using it for years. I think it's the best value for money. I'm not an expert, but as a recommendation from a mechanic, I have chosen it since I first bought it.
What can I add?
Indeed the best oil. The engine works more freely and the gears shift perfectly. I recommend it.
Owner of a Varadero mk2 2005 and I installed them yesterday to try them out! Perfect feeling! Immediately you feel the difference in the engine's performance! When I bought it, I used Valvoline 10/40 but I could really hear the engine being very dry and struggling, and the gears sounding 3 kilometers slower! Everything has been corrected! I will come back with impressions once I reach around 800-1000 kilometers!
I have a cbf 250. First time using this specific oil. It is simply AMAZING. It eliminated the little noise it had from the valves and the gearbox works like a joystick.
I have tried Motul and Castrol as well.
Nothing compares to Bel Rey.
So far, this specific lubricant has shown very good characteristics. It was installed on a Varadero 1000 with 120,000 km on the clock. The gear shifting is completely silent. I hope that it maintains the same performance until the next change and that no declining trend is observed
I put it on my Suzuki Address 125 scooter and have been using it for three months, and even though I tried other expensive oils, this one makes a difference for me. The gearbox became buttery smooth, it has never been like this before, and the engine noise has noticeably decreased. I highly recommend it for Suzuki if you have a multi-cylinder engine, choose the full synthetic option, it can handle sudden increases in RPM

I installed it in a Transalp 750, I prefer it over the 10W-30 that Honda recommends, due to the hot climate in Greece.
