    In CT600e 2003. Despite the many periods of inactivity, weeks or even 2 months, it starts right up. The battery is amazing, by far the best I have ever installed.

    I have it on my SYM HD Evo 200 for 8 years now, today when I measured it with 2 degrees Celsius outside, it showed me 12.34v when turned off, 9.8v when on the kickstart, and 14v when turned on. I use it daily in the city, covering 10km and always having the low beam on. YUASA, you are amazing!

    My engine had it from the factory. It lasted for one and a half years. The same lasted the GS that they recommended to me as better. Now I put the Yuasa again. They don't last long. The only solution is Lithium but it is expensive.

    For now, the battery seems very good. I have used the same brand before and it was a very good battery, that's why I bought it again!

    A great choice in the Kymco Agility 200i, so far no problems after one year of use. On 2/5/2003 it broke down, I'm going for a new one.

    4 years on a 250cc motorcycle and not once did it struggle to start, whether it was winter or summer, even though many times it was inactive for several days. If you also buy an economical charger, then the battery shows that it can last for over 5 years. Those who leave the bike inactive for weeks or only move it for very short distances, it is absolutely logical for it to deteriorate within a year. Once the battery drops below 12.2 volts, the battery is done, even if it is still very new. It is worth its money.
    Edit: 6 years and we continue, although the voltage has dropped slightly according to the meter, but it is not noticeable during startup. Let's see if it will survive this winter as well. The battery is informally made in China

    Decent battery but when you have the machine idle, you definitely need a battery maintainer, otherwise the battery dies in 1 year! Now, after several Yuasa purchases, I bought a Lithium battery to see and compare their quality, and I reserve the right to inform you in the future about my conclusions.
