Hi Guys, got the most recent email from my HONDA dealer which is like a little promotional/maintenance/specials thing they send out every season. Anyway they had a link for this site which I thought might be useful for those interested in swapping cogs and the effects it will have subject to tire/wheel size etc. It may have already been listed but it was new to me and I thought Id add it for the knowledge of the collective.
