Just picked up a 03 YZ450 the other day. Considering streeting it as a motard eventually, but I'd like to get familiar on the dirt first. Been riding a 01 KDX220 for the last 3 years. I like the power of the YZ. Never had a bike that will power up and 4th gear before. Seems the bike sat more than being ridden as it still has the original tires. The rear is shot so I'm looking at getting a new set. Having never bought dirt tires before, should I stick with the stock size and if so what compound? never knew they offered a variety of compounds dirt tires. Considering Bridgestones as I roadrace with them, but heard good things about the Maxxis tires also. Mostly ride trails in North GA, a monthly trip to DP, some ORVs. terrain ranges from sloppy trails to rocky trails and the occasional MX lap or two. I'd like the tires to last, but don't want to be sliding around in the GA clay. I do a lot of stop and go riding as I ride with the kids. Any problems with overheating? Should I just throw in some Water Wetter to be safe? The previous owner has never had the valves checked, so I plan on having them inspected to be safe.
