Part # 20668200
Tank Bag Sport

It's well made, it's easy to install and to use. It's very convenient. It's only negative is that it is small, but the description and pictures clearly show its size and so that is not a surprise. I can fit a wallet, smart phone, garage door opener, and a pair of gloves. I recommend it, I was looking for something easy and convenient to use and something that did not take away from the appearance of the bike. It does these things very well.

I just purchased this bag for my S1000XR and so far am very pleased with it. It is great for day trips especially since the OEM BMW bag (which I also have) is rather large and is very bulky when you must remove it to fuel up. This tank bag simply snaps off easily and just as quickly can be reattached after fueling or removing it to take your valuables with you if you make a stop for a meal. The quality as you might expect from Wunderlich is very good. The bag isn't very large but will carry everything you might need for a day trip, with ease. If you're going on a multi day ride...get a larger bag or use a tail bag in conjunction with this Sport Bag, which is what I do. I keep tools, tire repair, etc., in the tail bag and my wallet, phone, camera, sunglasses, hat, ear plugs and small items in this tank bag for which it is perfect. Yep, it's expensive but really is the only game in town for quality and ease of use on the XR.

I just got this tank bag last week and I'm really impressed with the build quality and capacity despite its small size inside. I've done a video review you can see here https://youtu.be/l_hBFRqiRpo
