DB Holders subframes and fairing brackets are made of high quality aluminium alloy and have a black powder coat finish. These subframes end fairing stays are suitable for race use, but do not have mounting points for street bike accessories such as passenger footrests and mirrors. Some fairing brackets have fibreglass air intakes included, reinforced with kevlar and carbon. DB Holders subframes fits all bodywork that uses the original mounting points. Very good choice add-on for your trackbike which is much cheaper than your stock subframe, and much lighter!
