I'm not sure about the legal stuff in your Country but it shouldn't be an issue. BMW tested and certified the bike claiming a top speed of "over 200 kmh". Therefore the tires required to certify the bike must have a speed rating of at least that. Now in reality, how often are you doing over 200? How about over 180? The onice should be on you. If you go over 180 and have a tire failure, that's your fault. What's the maximum speed limit in your country? In Canada, 120 kmh is the highest I've seen so the tire is safe for all legal speeds here with room to spare.
Bottom line......you know the speed rating so ride within it.
Any lawyers here??
