deathsentry0 Posted November 13, 2011 Share Posted November 13, 2011 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.

PeterC Posted November 13, 2011 Share Posted November 13, 2011 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. Link to comment Share on other sites More sharing options...
