+1 for the Dakar shield:
Bike that inspired me to try the Dakar screen^^^
My Te-610...with the Dakar ^^^
The protection is great and at the angle I have it mounted I get very little buffetting if any. The wind hits me right at the top of the helmet so there is also little pressure on the Head reducing neck strain...Dakar Shield is a great option for any dualsport IMHO...
