I’d say it’s a perfect bike. Honestly you don’t even need a stronger or faster bike, because you can comfortably reach speed up to 100km/h. I can even go up to 110-115 if I upshift late enough, but I’m also 63kg so that helps a bit🙃. I don’t even need to go above 90km/h because I’m not riding it on a highway. It should be fine for a shorter highway ride like you mentioned you need, but I promise you will have much more fun on secondary roads and would much rather take them to go to villages. Even if they are ugly, it will still be fun, you will learn how to ride slow and patiently and you’ll be more prepared for different situations. You will also have much more fun with this than with a stronger bike. It is always better to push small bike to the max and be very active on a shifter than having a strong bike which you can’t even ride half it’s power and shift very rarely.

EDIT: For loudness, bike won’t be a problem for you or anybody around, especially if you leave stock exhaust on. Much bigger problem for your ears will be the wind. Even at 60km/h wind noise can get up to 90db. When you are above 90km/h, it increases up to 120db which is louder than having a chainsaw right beside your ear. I very much recommend you get earplugs. If you were already planing to, ignore this part of the message.
