In my ZZR 25o the Front wheel bearings are shot ..The previous owner must have had a smash as the wheel is also not straight...
How do i remove the bearings as they seem to be wedged inside .its difficu;t to hit them out due to th spacer inside.

if they are really wedged in there and you dont give two shits about the condition of them afterwards, using a drift/long flathead screwdriver and a hammer may be the go, assuming you can get purchase to force it out.
failing that perhaps a light bit of heat from a handheld torch on the aluminimum and using multigrips to yank it out?

the spacer inside the hub should have enough freeplay so that you can
sometimes the best *drift* to use in these situations is a 300mm long piece of solid round-section bar, about 6-8mm dia. You need to get a good purchase on the edge of the bearing, and make sure your hammer blow is sharp and sweet........move the wheel around, repeat, and with one or two good blows, the bearing will come out. Once the first side is out, the other side is easy - use the spacer as a second 'drift', and a larger piece of solid round-section as the outer drift. The other bearing will be heaps easier to remove, because you have a lot more room to get a decent *belt* in
.
I don't think these models had a circlip retainer for the bearing, it will be obvious if its fitted, and of course this has to be removed before you start using the *gentle persuader*
Only use heat from a torch as a last resort, apply only to the hub area around the bearing, and be *really careful*, its easy to overheat alloy hubs and stuff them in the blink of an eye ....

As the others have already stated, grab a Suzuki special tool (otherwise known as a hammer) and a good thick drift, and smash shit outta it till it pops out!
