what should be the first thing I do to my quad? 2005 honda 400ex?

 

Better tires and nerf bars. Id reccomend Maxxis Razr'2 for tires and AC racing propegs for nerfbars.

 

I'd get an exhaust.

 

Better to make it safer and handle better before making it faster.

 

Well it's all what you are looking for, do you want performance parts or do you want looks and protection parts. If you want performance than i'd look into an exhaust system, jet kit, airfilter to start with, if you want protection than i'd get a bumper, nerf bars, skid plates etc. I would still get nerfs first cuz they are a must when jumping.

Someone said tires?? i would definately leave them alone till they ware out, Stock 400Ex's tires are some of the best holding tires i have ever owned, i would go with the exhaust and stuff first, then if it dont handle good enough, widen it, but i alwaso thing they handle real good.
