Purchased a 2017 Sportsman 450 HO in Sept, 2017. Rode it till its first oil change came due. Winterized it, trickle charge on it. Turned key in April 2018 and its dead. No click. Dead. Onboard voltmeter read 11.7 V. Replaced battery. Turned key. Nothing. Turns out the starter solenoid was bad. In 2months of use. and four months of storage. Warranty expired at 6 mos. Onboard voltmeter read 11.7 V on the new battery too. So, Polaris supplies an inaccurate voltmeter and poor quality solenoids. Honda here I come.
