I'm buying something expensive for me, should I change the investment plan?

Hello everyone, I wanted to buy a bike for like 6500€ and idk if or how I should modify my investment plan to adabt to this purchase.

I'm 20M, 15k€ in savings, about 25k€ after tax per year income (could be 30k€ next year), about 400€ per month expenses (250€ essentials and 150€ on wants that could be cut out). I have extra 2750€ invested, and I'm investing 500€ a month at the moment.

Seen that I got an income and a good saving rate per month (about 1000 - 1200€), should I leave the DCA investment like it is or change it? Idk if the fact that my savings are gonna to be about half after I would make the purchase could affect somehow my investment strategy (for example that I will run out of money and can't contribute anymore to my investments).

At the moment I have no plans or obective to buy some kind of bigger car or house etc.
