I finally removed the stock bodywork off my 1000ss today. I'll be replacing it with Sharkskinz stuff, but I have a question for anyone that's used them. The body work has black plastic pieces inside to divert air on to the motor.

Does the sharkskinz bodywork have anything similar? Should I keep them? Are they even needed on a race bike?

It also has what appears to be insulation (man, it's heavy). I assume I can toss that.

Thanks.
