Hi guys I am new to the site, I am from South Wales in the UK and I have only been riding since May of this year but I have fallen in Love with it. I am not a fair weather rider and am happing to get out in any weather rain or shine I have an XT125 r black and silver which is my pride and joy as I sold my car just to buy it. I got on it today though and found that my speedometer is not registering, it was working last night but this morning it stays on zero, I was wondering if anyone knows what the problem could be? thanks
