I have one. My results with it have been indifferent.
Im 6ft 2 with a 34 inch inseam.
The quality is good - typical givi. Whilst its an improvement on the stock screen my helmet is still left in a buffeting zone so I have taken it off . I think it would be good if you were less than 5ft 10 tall.
So far I have brought the ermax touring screen and now the givi.It drives me mental that yamaha ruin a bike that has touring potential with such a poor screen. Still they are not alone- I had 2014 Vstrom 1000 that buffeted so bad it felt like your head was in a clothes dryer. The problem was solved when I got a givi airstream for it.
Im back to the short do it yourself screen that Fred designed- it works best for me.
Anyone in New Zealand want to buy an Ermax or Givi screen - send me a personal message
