KZ1000ST,1979 model, what kind of neck bearings?

Have to replace the fork seals and front tire, so figured a good time to replace the neck bearings. Does this model take needle bearings (no reason to replace) or ball bearings (gotta go) in the steering stem?
What would be the best tires fore/aft for handeling? Old ones are like a rock.
Thanks up front,
Ken

either way i think you are going to be installing tapered bearings (whatever) from what i can tell....my chain 79 is rollers..balls...i did some checking and was told by a pro mechanic self supporting shop owner/friend that the ones sold are all balls and they are good..spome complete with new dust seal rings ect...but that there is some better ones for 40$ more..he did not know the name just buy the more $ he said ...he has had less fitment issues and wear with more expensive ones....a call to Z-1 ent .com turned up no bad reviews of the all balls product from the salesman...no all balls bearing issues ever...great product...but...turns out they sell another set...for guess what...20-40$ more... does it matter...???i bought the more $ set and it has no seals included...

anyways Z1 enterprises will have em.... and mine ,on my bench to go in next were on my door step in 2 days

you want to look online for avon tires...roadriders

The ST was a fantastic bike, had tapered bearings from the factory, so I doubt they need replacement. They went all out on the ST. It looked like a MKII, but everything was heavy duty, heavier frame, forks, shocks, all bigger bodywork, tapered bearings, tubeless wheels and tires, first ever on a motorcycle I believe. All built like a tank, then in 1981 they went to he KZ1100 that was all back to light duty parts. I have the rare pleasure of owning a mint example of each, and put the ST next to the MKII and the ST is just a brute of a bike. Still the MKII is my favorite Kawasaki ever, but if I had to choose a street bike for function and parts availabilty was not a factor the KZ1000ST would be my number 1 pick. Sadly they kept the ST 2 short years and don't care to support parts for it which 90% of it's parts are unique to the model unfortunately.

Thanks for the suggestions, must admit, the MKII is an even sleeker styled bike,it's a brute 'beaut.
thanks,
Ken

Glad to know I can leave the steering head bearings alone, I used to have a Kawi 650 with roller bearings, felt like the steering had a detent in it till I switched to needle bearings.
Thanks,
Ken

Should be OK unless they rusted over the years.
