When trials riding, it is obvious that your trials motorcycle will become muddy. However, there are some key areas, such as the air box, you really dont want the mud to reach. Thus, EP have introduced the Evotech Rear Shock Mud Flap for the Gas Gas TXT GP 300 to their suite of trials motorcycle parts and accessories. The bespoke design of the thick, flexible guard gives a secure fit, offering another layer of mud protection for the air box.
