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

    Perfect oil for daily use in a moped modified to 150cc with an oil cooler, changes every 1000km, nothing has been heard about the gearbox or engine, and the bike is ridden hard, it has 15,000 kilometers, so if there was an issue it would have shown up by now. For me, it's perfect

    After 10,000km I won't put it back in the engine (bmw f650gs twin spark), in the city after a few kilometers the gearbox becomes a log and only with great pressure on the gear lever do the gears change. The liqui moly 15w-50 is much better and the gearbox works like a clock.

    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.

    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 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
