why does my rear wheel keep locking?

examiner sorry.

You didn't mention it at all, but I assume you're not using the rear brake as you're changing down?

Exactly the same thing used to happen to me, but was soon sorted when the art of blipping was explained to me

It'll still happen ocassionally when I'm being too eager with the ol' downshifting, and is definitely a pant-wetting experience!!

Blip blip and blip again....

Learn to blip and you could be on the journey to being a riding god.

I'd like to learn to blip, but as with everything I don't want to get it wrong and take a spill...

How far do u blip it? Do u drop the clutch at the blip or let it out as normal?

As you want to change down gear blip throttle clutch in down gear clutch out its a matter of timing.

chain loose was one thing i didn't mention. i think i've a bit too much play in mine, i can take it off the rear cog without tools. ok ok ok i made that bit up, but there's probably about 1 1/2 " movement. too much? the hand book reckons 1.2" max...

when i pul the clutch in , give it a little rev - miminal ammount -
as the rev counter peaks and is on its way down - pull the clutch out
.
after a while - when pulling the clutch out you will be able to keep the rev counter steady.

its easier on a 125 than a 600 btw

too loose i recon.
i had my chain come off the 125 when cornering - its not good to lose power on a corner-

should be able to pull it half way off the sprockets.
too much and its too lose

I don't understand why "blipping" should only apply to strokers when its all about matching engine speed to road speed. What difference does the engine stoke matter?
