I have recently purchased a KBC Force RR Speed Demon Gold helmet to replace my HJC CL-SP helmet. I purchased the KBC because I thought that the graphics look great and my old HJC wasn't sealing properly anymore. The differences between the helmets are the following. Both helmets are a small. I have a narrow head that I suppose you would call a rectangle. The KBC is fractionally smaller in the opening so that when I wear a balaclarva (spelling ?) under the helmet I have to push it on from above. Once on the padding inside is a little stiffer but I am hoping that it softens up over time. The visor has more positions and it closes with a definite snap. It will stay open in a cracked open position that is great for cold weather riding in slow traffic. It won't fog up on you. It has a built in nose guard. Good ventilation with lots of vents that can be opened or closed. The visor has a lip on the bottom that seals it when closed but when it is cracked open , looking through the lip distorts the view. Not a big deal but its there. The clip to snap the strap onto (the end) is short and therefore a little hard to find. THe visor on the HJC wouldn't seal properly anymore in the fully closed position. The KBC is very quiet in the ear area but you can hear the wind noise around the outside of the helmet. Thats normal though. Overall I am very happy with the KBC. Looks good, seals good, quiet inside, ventilates well, and it is a good price. I purchased it on imotorcyclestore.com with free shipping. Got it in four days as it had to come from Texas to California. I had tried the helmet on at a bike shop so I knew that it was going to be a tight fit untill it softens up a bit. As I said, happy with the purchase.
