Yeah, really nice quality helmet from Premier; good venting, removable innner lining, visor is easy to change without tools. And not that expensive at all. More noise though then the Baehr Silencer I wore before.
I prefer a simple colour scheme, rather then the colourfull, exploding patterns of most helmets.
I used to cover the base of my Blackbird fairing in thick black tape to stop it scrapping the fairing. Unfortunatly on a funny shapped corner still managed to tip it in too much and lowsided onto the grass.
I hope I dont get the same problem with the Beemer.
Engine clearance? For me it's sufficient. As you can see on the pics, I'm not really hanging off. The instructor advised me to do so, that way you won't need to lean the bike over that much / reach even higher corner speed.
Running Michelin Pilot Powers instead of BT020's on former occasions. These give great confidence, such that I dare to push it a bit harder.
