I have a Kawasaki ER5, 07, with 5250 miles on the clock. For some months I have been experiencing rear wheel slide. Like when having to pull up sharply, the rear wheel sometimes fishtails, and yesterday, on a dry road, when going round a roundabout, felt a slight slide to the left. Seems to me that the rear wheel is not gripping the road surface? But more noticeable on right hand turns than left? With only 5250 miles, still plenty of tread. Anyone have any ideas on this?
Rear wheel slide?

What's the shape of the tyre? If you run your hand over it has it squared off/does it feel 'round'?
Pressure still okay?
Think those are the two main things I'd check, but I'm sure someone with more knowledge will have a better idea
Tyre pressure and depth
On checking the handbook, confusing tyre pressures ? Got " 95.5~181 kg ( 215~400lb ) load" in one box, and in another box next to it "280 kPa ( 2.80 kg/cm, 41psi )". Don't know what these figures mean, other than 41psi. So as was 31psi, put more air in to bring it up to 41psi. Also, on checking the tread, got 4mm depth on the outside of the tyre, and 3mm in the centre. Probably need a new tyre soon? Anyway, have to see if the extra 10psi has made a difference?
I ran my Battlax 021s at 36/42 front/rear. The owner handbook only really holds true for the OEM tyres, and even then it's perhaps to be taken with a pinch of salt; check your tyre manufacturer's website/Google for the specific tyre + bike model recommendations on pressures, but 10psi could definitely make a difference!
Bike tyres are normally 'safe' down to around 1mm tread so no need to replace yet unless there's something off with them (or you have money to spare).
Thanks for that. Today not so windy in Essex like the gale force winds yesterday, so will take it for a spin. Post how it went later.
