Joe Rocket RKT Prime Helment
 

Used it now for a month. My understanding is that Joe Rocket markets these helmets which are made for them my HJC. I opted to go with this helmet based on my previous HJC helmet. Purchased for $152.00 (US).

Certification: Snell 2010 and DOT
Aerodynamics: Good
Shell construction: Composite
Fit: Good, very comfortable. Same as my previous HJC.
Shield: Replaces easily. Came with clear with Pin Lock feature. I swapped over my old tinted visor. (Interchangeable with HJC.) Appears to seal well but can't say for sure, no water leakage and no wind whistle, see noise comment.
Overall finish: Good, some minor paint/color imperfections.
Liner: Removable and washable liner and cheek pads. Fit and finish is good.
Air Flow: Excellent, cooling/defogging is no problem.
Noise: Terrible, noise volume at freeway+ speeds will almost deafen you. Ear plugs are mandatory for any extended time at speed.
