It also appears Honda may be getting back into the game, not sure the extent of it though. From atvmotocross.com -
"For the 2016 Mtn Dew ATV Motocross Championship, Joel Hetrick, David Haagsma, and Grayson Eller have joined forces to form the new Maxxis/Liquid Wrench/Elka/Honda Team. Besides just a great lineup of racers, the new team also has some of the best mechanics in the industry with Paul Turner, Allan McCostlin, and Shawn Ulikowski joining the team as well, which will surely make for a championship contending combination."
