How rare is it to find a KTM Motard in Japan?

Hello. I live in Italy, but would like to study abroad in Japan on an Erasmus exchange program. I've been interested in motorcycles for a long time, and I'm also trying to get my 125cc license. I had some doubts. I previously posted about motorcycle culture on Reddit, and I received a comment that many teenagers were riding scooters. They were exaggerating, and I couldn't get the idea out of my head that I didn't want to embarrass people on scooters too much, so I asked myself two questions. One is a more general question, namely, are there a lot of moto bikes (especially KTM and TM) in Tokyo? "A place where I'm likely to go to study." And a question to all the enthusiasts out there: What kind of tuning do they do? What about scooters and bikes? At the very least, do you need something to keep them going? (For example, is 50 horsepower enough?)
