philhill Posted October 18, 2009 Share Posted October 18, 2009 Hi, have just got my DT175MX running again, see previous threads, and I keep feeling for a bigger gear when riding in top. As far as I know I am on standard chain sprockets for a 125. Is the 175 different and if not which way do I go, bigger front sprocket or smaller rear. Anyone know, done it before? Thanks Phil Link to comment Share on other sites More sharing options...

Thanks Phil Hi Phil, standard front for a 175 is 15 teeth, strangely enough standard for a 125 is 16 teeth so that is higher geared. However you can get standard +1 or +2 (for higher gearing), and aso -1 or -2 (for lower gearing) from wemoto for example, the only problem is the postal strike!

kobascle Posted October 18, 2009 Share Posted October 18, 2009 Going 2-3 teeth larger in the front or smaller in the rear should gain you about a 5 mph increase in top end speed. Hope this helps. Link to comment Share on other sites More sharing options...

Hope this helps. 2 teeth bigger will take top speed from 65 to 73.5 mph Link to comment Share on other sites More sharing options...
