They are a great idea, a little over priced in my opinion, l ended up making my own for about a third of the cost and it work's fine, l took a bike all the way from Brisbane to Melbourne and back 6 month's ago with no drama's at all, you can get an accessory Number plate from main roads department for $30 and put a trailer board on for your light's and away ya go........... Bike's l've had on my rack include- CR250-EXC300-Husky610-KTM 520EXC..........
