I was planning on selling my quad because i've been jumping it and getting some nice air but the landing is so hard it beats the heck out of me. Thats the only thing wrong about my quad. If i sell it i'm hopeing to get 2800. I wanted a larder quad like a 250r or 400ex but i don't have that much money. so i was wondering if a used 300ex can be modified enough so that i can jump it and have it really reliable. would a 300ex be worth modifying an keeping for along time or should i just wait and buy a 400ex
