Oh I would definitely still balance them. There's weights on your wheel already. Are they there because the last tire was out of balance, or the wheel itself? No way to know. It's worth the time and cost of building a simple stand out of 2x4's. I've had good luck with the balancing sealants like Ride-On once it's pretty close. And it helps with small punctures.
Is that the Road 5? I have the Road 4's on my Z1000 and have loved them, best tire I've ran so far. Almost replacement time, so it's probably getting the 6's for next spring.
