Well I don't know about the 1cm difference, but the gasgas feels like a much bigger bike, I have both bikes.
Rake, head angle etc will effect reach. I guess my question was only aimed at people that have first hand experience with the new 23+ gasgas vs other bikes as I initially asked, no real reason to analyze dimensions too much - Like I dont know why link a long video that analyzes pictures (obviously those bikes will have different sag in whatever pics he grabbed) thats talking about a 2020 gasgas/sherco etc, when clearly I have a different generation of this bike.
I appreciate trying to help but this isnt helping
