B&W Bike Bar
I also use the B&W Bike Bar, 2007 Road Star 1700. No need for tie downs. Just use the clamp on the frame, drive the bike onto the bolted platform on the RV garage floor, the clamp or bar on the bike will securely clamp onto the bolted platform and you're good to go. Again, no need for tiedowns, the 850 pound bike is secured to the floor of the RV garage. The bike bar is a bit pricey at $350, but well worth the ease of use, convenience and knowing the bike is secure. I have a XLR AMP 395, no tanks below my floor, installation was easy, about 1 hour. Good luck...
