my first bike [...] I’m struggling to decide between a sport bike or a naked style bike. I’m thinking the 675 model would be great to grow into as I learn.
Why in the FUCK are you trying to kill yourself? You have zero experience and yet you're gunning for a bike that will hit 100 MPH (with a lot left to go) if you sneeze wrong. To put it into perspective, that bike will out-accelerate a C8 Z06 Corvette, and hang with a C8 ZR1.
Don't be stupid. Get a dual-sport, like a CRF250 or something. Or a Grom.
Something to keep in mind, as it also applies to motorcycles: "slow car fast" is far more enjoyable than "fast car slow".
