We [M.A.P] have a very sound accessory policy, we sell what we "USE & ABUSE"!   (says it all really!)
We were looking around to replace our aging flip helmets & did not intend to become helmet stockiest ... But !

Finding (not so easy) / buying / Owning etc, a Zeus 2100B Adventure (call it Dual Sport if you like)  has been great
(we were going down a much dearer route in both cases)!  It also saw us try the 3000 to replace aging BM Systems Helmets too.
We were sold, both on quality, on price, comfort etc.   
For a road test of the 2100B Dual Sport, have a look at an owners review @ webbikeworld

 2100b RRP $249                                    3000a RRP $299  (3000 now superseded)

  Range of visors, replaceable liners etc!                                      Range of visors, replaceable liners & converts to a jet!   
  We wont hold a large range @ M.A.P, & really we are expecting these to be for local riders who can drop in and test fit! 

1.    Determine your fit
      – Measure with a tape horizontally around your head at a height of 2.5cm above your eyebrows.
      Then choose the helmet size closest to your head.
2. Try the helmet
      – Widen the helmet opening by pulling both chin strap and wear the helmet. If the helmet is not tight, it is too big for you.
      Choose a smaller size and you should feel tight.
3.   Check fitting
      – Make sure the inner lining fits securely around your head by pressing both your hands each side of the helmet and turn
      Left and right.  See if it can be moved easily. If yes, choose the smaller size.
4.   Check retention system – Fasten the chin strap as tight as possible.
     - Then put your hand at the chin area and pull upwards. If the helmet shows any indication to come off, do not use the helmet.

The following is a general guide to sizing obtained from the web .... (not necessarily endorsed by us, we always test fit etc)

The Zeus helmets tend to be a little snug.  If in doubt consider the next size up.
