How do i change a flat rear tyre on a Yamaha SR 125,?
Answers:
Hi ,
Changing the Rear Tyre is best done by a Motorcycle Garage as it also involves balancing the wheel , ( very important to stop wobbles at speeds over 40mph ) and the Brakes will need to be dis-engaged & the drive chain has to be tensioned correctly.
If you do not have a shop close to you that you can push the bike to then do the following :-
Make sure you can pump up the tyre, a High Pressure foot pump is best.
Purchase either some Oke tyre seal fluid or an emergency pressurised can of tyre reinflater, once you have done this, following the instructions on the can carefully, you will then be able to ride the bike to the nearest motorcycle repair shop.
A new Rear tyre for the SR 125 is about £ 45.00 & with fitting you can expect to pay about £ 70 as a total , but check with the repair shop. Don't try to do it yourself it isn't worth it.
I hope that this helps . Colin
get your dad to do it
remove the rear wheel, back off the chain adjustment, remove the tyre on one side and pull out the tube, fix as you would a bike tube and reverse the process.
Its a longish job - and mucky, and cannot be rushed
pay someone else to do it
I Guess it has an inner tube, you have to remove the wheel, undo the rear spindle (Axle) dont lose the spacers, and I think brake anchor bar and brake pull rod.
Changing the inner tube is a marginal DIY job as these use such a wide tyre, best left to a tyre place but, it does make the bike hopelessly unreliable if you cannot even fix a puncture at the roadside. Join the RAC was my solution when I could no longer remove the tyres on my bike (Guzzi 1000)
Remove the tyre with proper tyre levers, not screwdrivers
If you can get the tube out use a Motorcycle puncture repair kit, Not Bicycle, pump it up slightly to check for leaks, not too hard and stuff it beack into the tyre and pump it up. Always safest to use a new tube.
Dont bother with balance on a back wheel but make absolutely sure the tyre is on evenly it should spin within less than 10 mm up and down 2mm better, wobble will be from incorect fitting not balance on a slow sub 75 mph 125.
Finally make sure the brake anchor is tight , the brake is adjusted to work with your weight in nthe saddle and that the wheel is in straight and the Wheel Spindle nut is good and tight.
with a srew driver!! not how bout a wrench or a pinnapple!!
really I don't know that one but I just had to say that.
Actually,
you should take off the wole wheel not just tire.
You first have to remove the wheel from the bike.
It's easy to change a tire or tube for someone that knows how to.
But if it's your first time, it's a knuckle buster, pain in the butt and you'll probably pinch the tube 2-3 times (each time you pinch the tube, you need a new one).
Take it to a shop or get someone to show you how to do it.
