I have a 06 YZ450f and am trying to find a good suspension company. Enzo and TBT seem to be the most popular in my area. I race race mainly offroad, everything from mudy tight woods to open desert. I am 5'8" 185lbs. Been racing for two years riding for ten, trying to bump up to the B class. If anybody has any good experiences or bad that would make my decision alot easaier. Some stock setups and ergo may also help, the bike is completely stock as far as that goes.
