Hey guys, i got into mx and trial ridding about a year ago when i got my first bike (a ttr-125) an i probably outgrew the bike b4 i ever owned it because i had to get a bike i could share with my 9 year old brother who is half my size. I am ready to move up to a bigger bike now and will most likely buy a semi used bike. Here is the delima, I do about half mx riding (what i can on the ttr cause im 6'2' and 200lbs) and half trail ridding. I like the power from 250's but would consider a 400-450 also. I was wondering if it would be better to get a Yz250f if i went with a 250 over the Wr because i have heard that the stock wr's are sluggish at the bottom of the powerband. Another thing that worries me is that i know that mx bikes are ment for the mx track and not trails and if the yz would overheat with alot of trail ridding. Basically what im getting to is would it be easier to fix the sluggish WR thing or make a Yz not burn up on trials. Im really leaning toward the Yz because i really like Mx ridding and i know it will perform better stock but dont want to get something that i will have trouble adapting to my other ridding uses. Thanks in advance for your help.
