Yes your tires almost with 99.9999% accuracy have tubes but....

I was under the impression that tubless wheels have a different rim profile that provides a better seal than tube type wheels. Is this not the case?

I just looked at the tires to see what size was actually on there (not sure why I didn't before).
The rear tire is already a 120/90-18 and the front is a 100/90-19.
Also, the rear tire, at least, is tubeless. Couldn't see very well to tell if the front is also or not.

Most, if not all, tubeless tires made for the street can be used with tubes.
I posted a video in the Bike Related forum of a guy racing a KZ750 on 7 year old Bridgestone BT45 tires.

I ride in the city and there are many idiots who cut you off once one got in front of me and slammed his brakes. Both tires skidded when the front at least should have grabbed. Now picture that in the rain. Ride it awhile and see where it gets you.

Just for info please. If old tires are dangerous I'm in deep crap because I just checked mine out.
1977 KZ650 Tires 2 yrs on the bike but 13 yrs old
1977 KZ650 Replaced in 1994
1978 KZ650 Replaced in 1994
1978 KZ650 Original
1979 KZ1000 Replaced in 1991
1980 KZ1000 Original
1974 H2 Replaced in 1993
On top of that these tires were probably "old" as I used to buy tires sometimes 6 or 8 at once and store them in the garage. State of the art 1930 garage though:laugh:

You are correct.Check the rear wheel size again. I would think the rear rim was 18" and not 19" but I could be wrong as I have never owned a 750 twin.
Front: 3.25H-19 4PR
Rear: 4.00H-18 4PR
Metric equivs are:
100-90-19 Front
110-90-18 Rear

I've now lived by this rule for 90,000 miles of riding and only ride if I'm comfortable with my tires. I just replaced two tires last week that looked "Brand New" still had the nubs on the tread, but they were 6 years old a dry rotted.
