Later on, this disturbs the bike’s casual performance and drive. Because once your engine gets too hot, you will get sure stutters while driving the vehicle. 


Check the coolant fan every 2-3 months. Always try to keep it clean and tidy. You’ll usually find it covered with dust and other particles when you cover a long journey. A small cleaning after the whole tour might minimize or entirely remove any future problems. 

3. Engine Problems and Malfunctioning

Load is a word the engine of Polaris sportsman 850 fears the most. Excess load on the bike and dreaming of a havoc ride are impossible with the 850 models. 

One of the most common symptoms of excess load on the engine is it stops working suddenly and restarts on its own. You need to clutch the speed up for a proper direction, then. 

Moreover, you’ll find the lights and other stuff on the vehicle go off during the ride. That’s entirely unexpected because you might be driving at night. All this happens when you drive the bike for a long time at high-speed verse conditions. In short, the engine got some serious issues while driving it with its whole stress on.

4. Heating Problems

While driving the Polaris 850 for test purposes, we found that the right side of the shield panel becomes too hot after some time. And with time goes on, there are symptoms of melting of the shield. 

And our assumption says that the problem can lead to catching fire on your bike. The engine and the bike’s body tend to become hotter then. As a ride, you won’t feel good riding the bike on it. 


Give a rest to the bike after riding for a long time. Also, speeding up in adverse conditions won’t bring any virtue to the bike. You can enjoy the best ride with a moderate speed at the most challenging places, but certainly not when you speed up.

We recommend safe and calm driving with the proper precaution to avoid accidents or steer failure issues. Because at that rate, even the most experienced driver will face trouble controlling the bike. If needed, diagnose your power steering before every long ride you go on it.
