If you own an Arctic Cat 400 or Suzuki Eiger 400, chances are that you’ve experienced or at least heard of the flywheel failure that plagues these otherwise great ATVs. One minute you’re riding along and everything is running smoothly, and out of nowhere and for no apparent reason your engine coughs and you roll to a stop. You know you’re not out of fuel, but it doesn’t take long to realize you are out of spark, and that points to the dreaded electrical gremlins.

When Polaris introduced the ACE platform a year and a half ago, we knew it was only a matter of time before they would follow it up with additional single seat models. It wasn’t a long wait. Later in the year came the ACE 570, and most recently they’ve unleashed the new ACE 900 SP.
