This is rather a good decision. You might have seen cars moving about with different colors of doors and bumpers. Well these people purchase second hand body parts for their cars. Later they would apply a simple paint job on them and get the desired look. This is a lot better than wasting money over brand new bumpers. The over all cost of second hand bumpers along with paint job is lesser than a new bumper. As far as performance ATV parts are concerned, well they must not be bought second hand.
The only reason why you would end up selling a performance part is because it is about to be worn out. Mostly people don’t bother with it; they simply throw away such parts. A dealer would take such thrown away parts and fix them up. The problem with these parts is that they still do not provide proper performance. This could result in giving birth to some other problem regarding your vehicle. Mostly dealers would obtain these parts from vehicles which are in scrap yard. Now you can imagine why it is not wise to purchase second hand performance ATV parts.
If you are looking for brand new parts, well the internet would provide with a wide variety of them. Over the internet you would easily find parts which fit in your budget. Make sure that the parts come along with a returnable warranty. This is important as the part might not fit in your ATV.
