Need tips: rebuilding my 2021 Z650 after an accident

I'm new here and I'm looking for some advice on rebuilding my 2021 Z650 after a low-speed accident. I was T-boned under 20mph, which thankfully my frame slider absorbed most of the impact, but the bike still took a hit. Damage includes broken plastics, a punctured radiator and smushed mount, bent bars, and I'm hoping the forks are just twisted in the triple tree rather than actually bent. The front wheel, tire, and brake seem okay, and the electrics survived even though the fuse panel cover and surrounding plastics got smashed. I've also got some minor scratches on the tank and rear.

I'm trying to disassemble everything now, starting from stripping the bars, plastics, and radiator. I'll be draining the tank, oil, and what's left of the coolant. I'll definitely need a new battery too. I'm planning to have a shop check out the forks to be safe. My goal is to get it back on the road as a personalized street fighter, so I'm also looking into aftermarket bars, a round headlight, different plastics, and bar-end mirrors. Any tips or recommendations on parts, or just general advice for this kind of rebuild, would be greatly appreciated!
 
Hey, swap the radiator with an upgraded aftermarket one for better cooling, and replace the bent bars with Renthal or ProTaper bars for improved strength and comfort

You're doin alright, disassemble carefully and get the forks checked by a shop for peace of mind. For parts, Renthal bars and a round headlight are solid choices for that street fighter style, plus bar end mirrors fit the look. Replace the radiator and battery ASAP, and check the frame and wiring while youre at it. Take your time, stay organized, and you'll have a decent custom bike before you know it.
 
Glad you're okay and still want to get your bike in running shape. Before you start tearing things down, sourcing parts and putting things back together, I'd check the frame first. If it's bent I wouldn't bother too much it that bike. It won't be aligned and will never track straight.
 
Hey @Macron_2000, glad you’re okay after that hit. Take your time stripping it down, check the forks and frame carefully, and the Renthal bars and round headlight are a solid start for the street fighter look.
