Posted November 13, 201113 yr Hi Guys need suggestion what are the primary things I need to modify my YBR-125. Stock parts, maximum speed I can muster with it is 105Kph. I was thinking about changing size for front and end sprockets then transmission gears but additional information would be alot of help.
November 13, 201113 yr Look around the forum - there are lots of people like you, no intro, asking for help. The best advice, which most don't take, is if you want it to be faster get a bigger bike.
