I started with the Cruz tool it, then took a few things out and added a few. I have tools for changing tires on the road, small slime air compressor, Genuine Innovations 45 gram co2 cartridges to seal newly mounted tires, GI tire plugging kit, Motion Pro Bead Pro tire breaker set, BMW spark plug puller tool, and oil filter wrench. I also have a fuel transfer syphon hose, GS911.
Your right, this stuff adds a lot of weight. And it is held in the left pannier all the time. For an RT, not sure you need all this stuff. Especially if your not traveling in the states, as help is usually just a phone call away. Oh, and don't forget your MOA book.
