Yes I could google it but I have a feeling like cafe racers a lot of it is opinion .. what makes it a brat bike?
A rose by any other name mah frien...
the general brat style is usually a bike that doesn't focus so much on looking polished. not necessarily super-gnarly/ugly or all sprayed black like some rat bikes or beaters, but definitely not candy paint and polished everything.
Maybe a little rust but for the most part everything works fine. Usually there's a bit of originality / fabrication involved.
I can't think of any brats that are chopped (hardtail).
Classified moto does a really good contemporary brat-style bike imo.
