Hi guys I'm currently in the market for a trail converted MXZX 440 and have a few (06,07's) that I am interested in, but then today I found an 07 600 mod that has been trail converted as well that is close to me. The 600 mod has similar miles to the 440's (2000-2500mi) and is also very close in price, give or take a few hundred. I mainly do most of my riding in some fields and pits around my house, but do go off and ride some trails that are local as well (never more than 100 miles on a ride). My question is which is the better way to go since they are both trail converted already? The 600 mod looks to be in real nice shape, but how easy are parts to find in case something goes wrong engine wise compared to a 440? Any advice would be greatly appreciated!
