Used cheaply good, motorcycle purchase?

Hello, I’ve been passionate about motorcycle since I was 15 and I started moped with a suzuki 50ccm terrain. At about 18 I had a 125cc chopper from daylim. Last year I bought a swallow from simson where I got my first real screwdriver experience. Now I’m about to do the big motorcycle driver’s license and start so slowly what it’s supposed to be for a motorcycle. What’s clear, I’m a student and therefore, all the cheaper the better. I su What requirements do I have? Actually, I’m relatively open to everything. That means, it’s secondary to what it looks like and how much power it has. In the foreground are price reliability and durability. I looked around. and so far the cb 450 with 27 or 36 hp looked quite cheap. It consumes little even if it’s the 27 hp version. What do you think? Which motorcyclists are eligible for? Mfg cheap motorra d buy
