The first stand set my son bought was that Venom set. The front will definitely contact the stock plastics under the headlight, you can remove the little fairing piece though fairly easy, two bolts, two plastic rivets. The rear, we've never had a problem with but it has always been used gingerly, and you have to always make sure the holding screws into the mount holders are tight, they loosen up easily just from simple use. Since there isn't one available, I made a mount so I could use GP lift.
Like the others have said, you get what you pay for and they covered the reasons. I have mostly Pit Bull stands, front and rear, and one Woodcraft front triple lift, either are much more solid lifts, the Venom doesn't really compare. We only use the Venom rear lift now for a bike that has spools, and to just sit on. I will be getting a Woodcraft rear stand for the reason Brendan brought up about adjustable height for when changing rear tires. A huge improvement to changing the rear is having that assembly captive, changing the rear is breeze now. The Fast Frank work and captive spacers. <Chef's kiss>
