I longed for one of these suites, an deventually stumped up fo rone.
What a load of crap. I have to put up with it because it cost a fortune, but it is nowhere near as good as the price would have you indicate. It lets the rain in, even with the gortex liner. The legs are cramped, uncomfortable but I do have to say, warm, btu again the gortex liner doesn't work.
I have a cheaper jacket, an Ixon Ranger - it has the gortex IN the jacket, so the jacket stays dry too - the quilted liner is warmer than the rallye jacket. Style is not so good, but features are much better.
I ride roughly 40,000 miles a year. I am out most days doing reasonable mileage and I need a set of clothes that do what bike riders need them to do - the Rallye outfit is fit for May - October only. A very expensive mistake and one that I won't make again.
It is still the suit I wanted. I still like the way it looks, but it is a let down on the practicality stakes. Oh, and the cuffs - I have yet to find a way to stop the rain going up the sleeves, unless you wear old fashioned gauntlets.
When a mate of mine and I first tried on a Rallye II suit we both fell in love with them and despite me having a knawing sense that I should get a Rukka I ignored it and we both ended up buying them for an RTW. They both leaked live sieves in the rain.

He got a replacement Gore-tex liner and that still leaked

-We met another English guy in Canada and his also leaked.

We re-proofed the gore-tex and Scotch-guarded the shell and still they leaked.

We both too regretted our decision when still, later in the evening, we were recovering from being wet and cold after a day of wet riding in Canada. This was a bitter pill to swallow. When you have shelled out around 700 quid for a suit for a 2 year trip and right near the beginning you're having to think about buying an over-suit it is gutting, especially having ignored the thought of 'Rukka'

My original jacket was stolen on Peru so I bought another one hoping that would be ok.....that also leaked

In the end I spent 3 years in my suit and I regretted it on so many occasions I can't tell you...or how often I was wet and cold because of it. I think that those who have Rallye II's that don't leak are in the minority as I've seen very few people defend them who regularly ride in foul weather.
All the connections for the various layers also started to fall to pieces as did the zips. I had a red jacket which started going salmon pink within a few months-Surely BMW can put some sort of UV resistant additive in the dye to keep them looking newer and fresher for longer !?!

This is nonsense for kit costing this much. I could rant for still longer. In short they look good, have lots of pockets, good ventilation and the BMW logo on them. If you want to stay dry buy elsewhere or get yourself a good over-suit.
If I were going again I'd by Rukka or maybe Hein Gericke. I met a German guy in Perth who said he'd had his first Rukka jacket for 16 years before it leaked..
