Brand new, Kafe Wheel Chock, doesn't need to be bolted in place. 100% portable and temporary. Simple and it's easy to use. If you ever trailer your bike, this is the ticket to get. There's a video on kafewheelchock.com if you want to see how it works. You won't damage the front fender on big bikes either.Harley Davidson victory Yamaha Honda Suzuki Kawasaki KTM BMW Polaris
