21M saved 7L want to buy a bike

As the title suggests, I am a 21 yo who just graduated. I’ve been working part time and doing internships throughout my college life and now have a portfolio of 7L.

I’ve always wanted to buy a bike and my family is strictly against it because of how dangerous it is. However, now that I’ve saved up I want to buy the Aprilia RS457 which is about 5L.

I know it’s a stupid decision in financial terms to break your investment for a depreciating asset.

I know I’ll always make more money but I’ll never be 21 again and have the chance to ride a bike.

Please let me know your thoughts and whether or not this would be a bad decision to make.

My portfolio is as follows:

Equity (HDFC Sec) - 2.4 L Equity (Zerodha) - 75k MF (HDFC Sec) - 1L + 5k Savings (a/c) - 2.5L Savings (FD) - 10k Total networth: 6.8L
