Check out "Ride on" it is great stuff. Balances, and seals if you have a puncture. It is water soluble, washes off with a hose. I had a rear flat on my Rocket with only 1500 miles. Was a real pain, on the side of the highway, trying to get plugs in the hole, and aired up. Now with ride on, I don't worry. Put it in my Rocket, then my Kawasaki ZRX1200r, then in all 4 tires of my jeep! The dealer where I bought my Rocket, has dropped the Triumph brand, but they still mount my tires, "IF" I bring in the wheels only. They would not mount anything but Metzler, if I took the bike in to them. The last rear Bridgstone I had them mount, took 3 guys on the tire machine, but they got it done, for $20, I left a $10 tip. The rear can be a *****, as there's not much of a drop down in the center of the wheel.
