Used it today, but just a short commute.
HJC RPHA 10+ Lorenzo Ghost - Medium
Previous lid is a small shell XR1100 Shoei, so comparing to that.
Pro's
40grams lighter fully fitted with chin curtain etc
Quieter
Potentially less buffeting from the airflow, inside around the mouth (chin curtain definitly working)
Looks cool ha haa
Good time to wear it with 99 on the top of the MotoGP standings!
DEAL: ?299 from SportsBikeShop, couldn't justify any other alternative.
Same
Pinlock visors, always a god send, just lacking much of a variety.
Visor swap easy
Comfort/padding - different but equally good.
Con's
Lacks the ear cutouts of the shoei, this is probably why it's quieter, but I spend longer putting it on as I have to unfold my ears by shoving a digit through the visor apature each time.
Vision...I'm not sure if it's real yet but the visor and pinlock might distort my sight in a way the shoei never did. But my eyes were watering from wind when I put the visor down and that too may have played a part. Might need to re calibrate my brain to deal with the optics. (IE get used to it).
Potentially my nose is a bit too close to the chin section of the shell. In a frontal impact I think I'd end up breaking it :-/
Unknowns
Wet weather performance.
High Speed - stability/airflow/noise/visor seal
Comfort with my custom earpieces
I too looked at the Shark Carbon, and felt it was an equal risk, yet significantly more expensive at the current time. Thus it was ruled out solely on cost. And I think it's pinlock-able not pinlock ready (ie you have to fit the bits - could be wrong there). Pinlock is a big thing for me - I hate nose/breath guards.
I think it's worth ?300, the NXR/X-Spirit 2 and Shark Carbon-R were the other options, 2 are almost twice as much to buy the NXR I felt would be limited in the same ways as the XR1100, rightly or wrongly.
