I recently purchased a 2016 1000-4 and I was very disappointed in the ride quality. The car would do good in the big hits but was atrocious in the washboard and small chatter. After hours of trying to tune the stock suspension I bit the bullet and purchased the stage 3+ spring/crossover collar package from Shock Therapy. In a nutshell it is a night and day improvement. It’s like riding on a pillow compared to the crap stock setup. I also gained probably 2″ in ground clearance.
I’m just surprised that Polaris just wouldn’t tune it like this from the factory.
I should probably add that I never touched the valving in the shocks.
