I was pretty thorough when researching a new helmet purchase. Since I already have a Shoei TZ1, I'm familiar with Shoei quality, and naturally researched their line of helmets. After feeling confident of my selection, I purchased one from MotoSport.com. So this review is not only a helmet review, but one reflecting my experience with MotoSport as well, who promptly shipped this helmet at a very competitive price, with free shipping.
Other than the obviously apparent quality construction of the helmet, it's performance has to be first in it's price class.
The venting: This is the first helmet I've used in 35 + years of riding, that did not fog on cooler evening rides. And I haven't even attached the INCLUDED pinlock shield. The venting alone has eliminated fogging with the shield completely closed. And it makes riding in an enclosed helmet feel less confining.
The aerodynamics: This is also the first time I've actually seen debris and insects be directed AROUND my head. I have to conclude this is due to the aerodynamic design, because my TZ1 sure takes a lot of hits!
Sound: Since I always wear earplugs under a helmet, it may not seem this particular quality of the helmet would make a difference. But, for me, it does. The air flows so smoothly around the helmet, that not only is it quieter, but there is significantly less buffeting.
Engineering: It's superb! Removable liner, perfect fit and comfort, excellent visibility and an easy to remove adjustable shield.
Bottom line is this. If you're looking for a top quality DOT and SNELL approved helmet, the Shoei RF1200 should be on your list of considerations.
