most of the time rider went for what they think they like and end up hating the bike, to me get something that is beginner friendly bike for a starter that you have no financial issue getting rid of it later.

majority of the issue owning at first is learning how big bike physics works like cornering, torque/throttle management, either you go big and learn it on the track or get the experience on the b-road. Reminder that it only takes 60km/h impact to 90% kill you (varies depending on angle, height, which body parts, etc)

as for riding gears, those who own big bikes eventually would own multiple version of it, example like helmet. For starter get a value for money gears like KYT or a decent daily mesh jacket, jeans with knee padding and a glove

for bike choice is up to you, but i do prefer for daily rider to go for a 2 cylinder naked bike, budget wise dominar d400 will do
