Used or rather new?

Hello com, I have a question for the general public, after eternal hi and here with colleagues, friends, acquaintances and the family. I am currently saving on the A2 driver’s license, i.e. 35kw or 48ps. I already have one or two models in mind, namely a Suzuki gsx or gs500e or something in the direction of Honda/ Kawasaki. Now of course I also need the suitable equipment. I thought I could get something needed for the beginning and upgrade it afterwards (e.g. helmet, combo etc.). but says a very experienced cross driver I just shouldn’t take a helmet under 250 euros and get everything new. But since my funds are limited option 1 would be more pleasant for the wallet that it is also enough for the bill. What do you say? Better new or enough needed for the beginning and I then upgrade to ? MfG Crunchi
