The Shoei XR-1100 is the replacement for the XR-1000. The design is very similar to the old one and the fit is nearly identical from what I found. The only difference I could really find is that the visibility of the 1100 is a little bit better than the 1000, mainly peripherally. This also greatly helps if you wear sunnies or spectacles as you can put them on quite easily while wearing the 1100. According the Shoei, the benefits aren't visible with many upgrades to the construction of the helmet which is supposed to increase the safety. I bought it at MCAS Auburn for $740 - they're having a special and they're usually $800. For designs they're $50 more than the plain matte black one I got. The 1000's are on special to clear out the old stock at $699 but there is limited sizes and styles. For an extra $50 I don't see why you wouldn't just get the 1100 though. The fit is perfect. No tight spots/loose spots. The strap goes up very tightly and it's very easy to button the strap back up. Obviously this will not be the same for everyone but I found the Shoei's to fit the best out of AGV, Arai, Rjays, Rock hard, HJC. I got a medium. The helmet is very quiet. Wind noise before 80kmph is non existent with the visor down. I had a shitty RXT helmet before which was louder with earplugs in than this helmet without. There is no whistling from a poorly fitting visor either, it fits extremely snugly around a rubber seal lining the visor bit. It also has a special type of visor mechanism which pulls it down quite tightly over this so the seal is completely airtight. The ventilation is very good with tactile vents which are easily move around with a gloved hand. They slide very firmly unlike some helmets which seem to have quite loose/flimsy vent covers. There is a vent at the front, 2 just above your eyebrows and FOUR along the back of the helmet. With the front vent open the visor doesn't fog up unless it's very cold and you're breathing hard. If it does, the visor opens very easily unlike other helmets which have somewhat harder visor mechanisms. Despite being very easily opened the mechanism is very sturdy and has a very quality feel. The helmet is also very light which is quite surprising as it isn't made of a carbon polymer. Moving your head around is very easy and puts no strain on your neck. I've worn it riding for 4 hours at a time and you can almost forget it's there. Visibility is very good. Looking forward at the road there is no interference from the lip of the helmet. The visor is also quite receded which makes checking your blind spot very easy. Overall, the helmet is spectacular. However it is up to you weather or not the $800 price tag is worth it. If you're in the market for a new one, definitely take a look at this helmet.
