Hiya, i have a yamaha DTR SM 125 my headlamp doesnt work and i am trying to find out how to replace the lightbulb. i have taken the fairing off but i cant seem to get into the headlamp. can you replace the lightbulb or do you have to replace the whole headlamp? if you can just replace the lightbulb what lightbulb do you use? thanks for your help guys

Ok Henri, first thing you need to do is buy the manual for your bike or even see if there is a PDF of it on the net, cos this will save you hours of time, cos all the answers to this and loads of other questions are in there.

Usually you just get at it from the back of the light, most of the time fairing does not need to be removed. Have a good look and a fiddle with the back of the light under the dash.
