Hi I got my x3 in april last year and got it custom fit by the Arai man, very snug, I have however found that it fogs up, even with the pinlock in in heavy rain. also it is quite a noisy lid so earplugs are a must.
I havent used my bike vey much in the last year, so all of this is based on the runs I have done.
late last year I was diagnosed with a prolapsed disc in my neck which gives me some pain, in an attempt to aleviate the pressure when riding I've removed the peak, so we'll see how that goes on, when I get back on it.
hope you are getting on okay with yours.
