Bike won't travel straight

[DevonDtr]

Hi, have an 04 yam dtre 125, had a new front wheel bearing and tyres, new pads in a hope to cure this problem! Basically when I let go of bars the bike leans to right, and when I use front brake it goes left!! Where else mechanical wise can I look..

Twisted subframe and slack chain

How severe is the "dive" and is the rear wheel properly aligned and secured? Have the wheel bearings been done properly and are they in good condition on the rear wheel? When moving the handlebars side to side is it nice and smooth or is there any notchyness or rough feeling?

[DevonDtr]

Everything's tight and as should be, was told rear bearings are fine. Its that bad that I have to sit off the bike to the left. Handlebar movement does feel rough

[jaffa90]

Have somebody balance the bike until the wheels are vertical with a spirit level and then see / feel if the bike wants to topple over.

[Tamsin]

if handlebars feel rough then head bearings need changing, that's not going to help the situation

[weasley]

Is the rear wheel straight in the swing arm? And the swingarm straight on the frame?

I would also mention twisted front forks but if the wheel's been out for bearings I'd assume it wouldn't go back together with exactly the same wrongness as before.

Well measuring things up, and excuse my lack of knowledge here, the bit where the bars clamp on is higher on left side so something bent up there : )

Are your arms the same length?

The new wheel bearings, tyre and brake pads; they were worn out and in need of replacing or they were replaced in the hope that they were responsible for your bike not running straight?

[DevonDtr]

Wheel bearing replaced due to play in wheel play, pads and tyres because of wear.

If your penis is large and hangs to the right then that's the problem. Try setting it straight on the tank.

You no answer first question, also get one wheel vertical and see if the other is as well.
