The worst thing I have ever tried, it burned them in record time, I almost got stuck with the scooter even though there is no problem

I use it on my Yamaha Tracer, where the mechanic recommended it to me and I noticed a difference during its installation, the gearbox softened

Nothing special, just a mineral oil for an old engine with tolerances. Don't expect increased performance, etc., it will simply reduce the motor noise and the lubricant consumption if, for example, you accidentally used 10W-40 in an old engine with tolerances. I used it a few times and I wasn't impressed, I will change it next time.
