The K1600 water pumps are the same, just have new vendor, per Victory BMW in Arizona.
I find it so incredibly amazing that BMW has not issued a recall on these water pumps yet.
Water Pump - Part #: 11517721959 - $277.20; Three O-Ring Sets - Part #'s: 11518523124 - $74.40; for a Parts Subtotal of $351.60. Naturally this is under the BMW Warranty and I've no idea if the labor rates were included in the $382.54 with tax.
Now here's the kicker, both Victory BMW and Scottsdale BMW have now replaced every K1600 they've sold that's reached 6K miles, every single one. This means that they have NOT replaced the water pump on sold machines with only a couple of thousand miles on them, but if our K1600's are reaching the first major service then the pumps are failing!
4 days from now Son Seth (15) and I are leaving for a 8K mile ride to Alaska and back, can you imagine how incensed and livid I would have been if this had failed on our ride!
I'm so baffled that BMWNA is not being proactive on this, only just waiting for the failures!
