Here at Pro-Action Suspension NJ, we take mass-produced motorcycles and build custom suspensions for them to the specific needs of the owner. We start by selecting the correct spring rates to uphold the weight of the motorcycle and rider. We then determine the correct Pro-Action Valve Bodies to be used to match up with the valving systems to be installed. Pro-Action uses many categories of shock and fork valving: Motocross, Supercross, Freestyle, Desert, Supermoto, Dirt Bike and Off Road. Once one of these categories is chosen, Pro-Action then designs a system that specifically fits the individual for height, weight, type of riding, class of competition, normal finishing position, and years of experience. Ground conditions and terrain are also considered. Pro-Action Suspension Of NJ is the leading edge of technology in Motocross Suspension tuning!
