http://2fiftycc.com/index.php?threads/honda-cbr250rr-mc22-specifications.2521/ You sure stock tire is 140/60? I have manuel cant be ****** looking it up on pc as im always on my phone but everything ive read on web says 140/70
I may be wrong never heard of putting 140/60 on mc22 might be just cause its cheaper to get 110/70 and 140/70 as set instead of two different profiled tyres
Yeah 140/60 is stock, truth be told I only worked that out recently my self when I was looking at tyre to rim width charts and was like hang on... Then all of a sudden started seeing everywhere that 140/60 is the correct size.
