I have the same light. Running on 2020 yz450f. Have never seen my voltage run low with it on lowbeam or highbeam. Light is great because it is a mixture of wide beam and spotlight LEDs so the light spread and throw are both great for the price and draw. And there is a handlebar mounted high/low switch. So if you want it on for daytime visibility, put it on low and draw less power. Want to night ride, put it on high. And they sell bike specific wire harnesses that make install a snap. Your bike should run it fine and any more light than this is overkill. But then, some like overkill. Ha. Just watch your draw for anything bigger. And, it's not about watts; it's about light output. Some cheapo lights don't put out near the light per watt as the good quality lights.
Cyclops makes a few lights and are knowledgeable about each bike's capacity so shoot them an email.
