They are about the same volume. From empty to the rim it will hold close to 26 liter but the officiel volume is a bit smaller - think the quoted 23 liter for the ABS

You can se my stats on https://www.spritmonitor.de/de/detai...ht/594575.html and i've often been over 24liter after 100km with the F blinking
