BLACK+GRAY Product Review
Black+Gray Plastic Wheel Chocks have a low profile and won't bend large disc brake
rotors like conventional steel hoop chocks can (and did on my Hayabusa),
and are available with a clever quick-disconnect mounting system using
Dzus fasteners. The optional quick-disconnect mounts can be installed entirely
from above the wooden floor in a trailer or box van, eliminating the need
to crawl around underneath the trailer or truck to install nuts on through-the-floor
bolts. The instructions for installation are clear, simple and easy-to-follow,
and the chocks have proven convenient in the Roadracing World box van.
They may be more difficult to install in the ribbed bed of a pickup truck,
simply because the chock side flanges must rest on a flat surface but for
box van or trailer use they're hard to beat. The Black+Gray chocks are
available in three widths, 4-inch for off-road and Vintage bikes, 6-inch
for modern sportbikes and racebikes, and 8-inch for use by riders who want
to tie their bike down rear-wheel first. ... I've used the 6-inch and 8-inch chocks with
quick-disconnect kits, all for tying in bikes front-wheel first, and they
have worked and held up great. The quick- disconnect kits make it very
convenient to remove the chocks when it's time to haul something other
than motorcycles, or to work in the trailer or box van.
