RF1000 vs RF1100 Sizes ? What was your old Medium helmet eg RF900 or RF1000 ? I bought my first RF1000 as large early '04 after feeling initially snug it got to loose when worn in so replaced it with a Medium in late '05, the Medium while initially tight wore in after a month or 2 to be still a great fit 5 and a bit years later. Have just replaced it with a medium RF1100 and it feels very snug at the moment but I cannot remember if the same snug as the RF1000 was when new so wondering if it'll break in to the same perfection. Any ideas on size differences between the 2 ?
