Hairspray is all well and good until you loan your bike to a "Death Gripper" who got cought in a rainstorm. Hairspray is water soluable, dont cha know?
I took it off and silicone glued it. BTW that POS didn't even clean my bike when he returned it. Learned my lesson. No one is ever riding my stuff again. Don't even ask.
Grips: I like the Domino's that came on my SD. They are thicker in the center and thinner towards the edges. When you lay you hand on them, there is better support for the middle of your hand. (That's just one of the many little quality touches that are on a KTM)
