2013 sportsman 550 xp, anything major flaws to look for before buying?

I was gunning for a 570 eps wich was setting me back 9000k but I just found out a relative want to sell his 2013 550xp with 1800km on the odo.

What are the weak spot to look for? does the 2013 have the pinch bolt on the sterring stem? Is there any recalls?

The condition is good and the price is exellent since he is selling it to me.

He rolled the bike to the side once while trying a turn slide on the first ride. I was there. The atv only tilted to one side and have scrapes on the side. He repainted them.

As a result the front rack cracked at the lock and ride attatchment, rear rack cracked too becose of passenger box. He rigged the rear one with a plywood to keep the seat. (the front rack will be tossed for a clamshel box anyway)

He also got water in the cvt in a medium sized water hole. Rushed to fast in it. I expect to change the belt and have the clutch fully cleaned. Just crossing fingers I wont have to change buttons and co…

It sounds like the atv was ridden very hard but it wasnt, just 2 new guy accidents.

I will change the air filter to a foam one and the rear rack too, add the polaris front box and use it as a dirt road rider.

Upgrades I should look for as I look do maintenance. I and not a hard guy on my stuff.

I was looking for a 570 eps until I heard of this bike. IMO the better bike is the 550. Right? I test rode both, the 550 three model years in a row and back then it was the best 500cc class bike for fun riding. The 570 is a nervous, fun , snappy engine but the heat problems turn me off since I ride only in the warmer days of summer for a 100 plus km a day. The 550 seems to have trickier maintenance, oil filter under the engine and belt location.

What is your opinions guys?
