ZX12R Head Shake

[hoffy]

too true, have heard radiator mounts can be a problem with too many mono's !

[frog]

That is a FACT about the mono's. Late rmodels worse than the first due to different mounts.

if you want to check the tyre being out of round. take a photo of the tyre from directly above and compare the profiles. I had the shakes on my gpx750 and it turned out that freeway work + camber had worn the tyre and shifted the centreline to the left 5-7mm. Hilarity ensued before i noted this fact and the bike stayed in the garage until i took the (very short, under 3km) trek to my local for a new pair of hoops.

I'll have to investigate a similar issue, but mine's when the bike is compression-braking with no hands on the bars (On private property of course! ) the front bars and wheel start shaking, only with no hands tho

Just buy a 10, their front ends are much more stable

When compared to an RZ500 maybe!?

1 . Listen to Gos (proviso we keep away from home brew octane enhancements everything's fine )
2. As mentioned , has the bike been binned ?? ie cracked headstem / weld / bearings (see pic)
3. Wheel bearings OK?
4. CORRECT wheel / bearing spacers?
5. Irregular tyre wear / scalloping / out of balance?
