Hi i am running stock tires now on the rear of my 300ex, I am going to get razrs, probable 20 inch, If i go to a 34 rear sprocket will I still have good low end?!? please reply

 

ya you will still have decent bottom end and better top end , since you are decreasing tire size you need to go up 1 tooth up front for every 2 inchwes you take off your tires . so a 14/34 would be like having a 13/34 because of the tires , so it would be a bit faster than stock but you wont loose much low end , i wouldnt recomend this for trail riding though .
