    after 3 months with the noise driving me insane a mate found the appears that the piston in the front brake caliper has siezed and the clicking/tapping noise is actually my brake pad rattling!! iv since been told that it is a common fault with this bike.Im not sure how dangerous this is but hopefully someone else wont be driven mad for months after reading this.Other than this problem i have to admit I love my gpr125 ;-)

I too would head for the speedo cable, but if you say you have checked it let's move on. Did you try "removing" the speedo calbe yet? Might be worth a try. After that we're looking at brakes, wheel bearing, or an interferance issue. Have you tried setting the front end up on a tire stand and rotating the wheel by hand to see if you can replicate it without riding? I would start there.

Xt 125 2007 speedo does not work would there be a obvious fault or would it need replacement if not what would be cost cheers

Your bike should have a cable driven speedometer. Look at the left side of front wheel...wheel axle is, you will see the speedometer cable attached. make sure that end is securely tightened, if it has come off, the internal cable may have slipped out. If its go under the speedometer housing and check the nut on the cable at that end...make sure its secure. Chances are it loosened off so cable was no longer engages into speedometer.
Other possibility...cable inside the outer sheath broke. A new cable is around $20 Cdn.

Hi Fishguy656, if you have a security alarm on your bike it's tied into your turn signals and any wiring problem you had with the rear tire must be addressed and correctly repaired.

A strange clicking noise in front when vehicle is moving

If this is a US production vehicle it is not a 2005.
Production stopped on the Axiom in 2004.
If you have a 2004 Axiom with a 3.5 Direct Injection engine it maybe due to low oil level. Check the oil and make sure it is at the correct level. Low oil level can cause the camphasers to rattle and cause engine damage. The phasers are only activated when the vehicle is in gear so you may not hear the noise when in park or neutral. Also maybe caused be loose campulley bolts. Severe engine damage may result if this is the case. Have it inspected soon to avoid damage.

Rattling noise

I know this may sound lame but I had a similar rattle and it was the catch on the fuel lid.
I put a little rubber on the tounge of the lock and now it is quiet.

My speedo always shows 0,any ideas on what it might be?

what type of bike is it. More than likely your speedo is cable drivien, you can check by following the wire from the back of the speedo to your front tire, if it is cable driven you may have broken the cable inside, this would probably be the cheapest and easiest fix.

Speedometer not working properly 2003 v-max

Easily checked. Get a friend to drive at an indicated speed in a car or another bike. Good reference point. If the speedo is driven by a cable remove at both ends and inspect for frayed wires on the inner cable. Just slide it out of the outer housing.

the connection on your front wheel where the speedo cable connects the link between the cable and gear more than likely broke you will need new speedo cable it happened to my cruiser

Speedometer wont move

You probably have a broken speedometer cable. Was the needle wagging back and forth and making strange noises periodically before it quit working?

If your unit is cable driven, get yourself an old piece of cable and insert it up into the speedo and then spin the cable while watching. If the needle jumps its pretty much assured the speedo head is ok and that your problem is in the cable or in the front wheel. Bill
