100% recommend the risers for the mirrors, you should hopefully find that the extra visibility afforded by these will ease the nerves as your situational awareness will be greater.
I had them on the SV and now the Daytona, as a slightly larger lad all I could see in my mirrors previously were my own shoulders!
This does not make for a relaxing ride, put the extenders on and it was like an epiphany.
Riding should never feel like a chore
