Well, the lil cbr has the most pathetic wheel/tyre combo at 80/17 100/17 i mean come on there are pushbikes with wider, thats fact too not just internet bull.

Anyway, looking at her boyfriends bike, then looking again with a tape measure, what do you know the spacings work to switch the wheels. So she may well get some yzf wheels in her cbr, get em powder coated repsol orange. 😈 Can feel the hate 😱

whatever works.
It'll be a Yamda then
