Lester Wheels:For the CB750K and CB500/550KFront:
The fronts are interchangeable as long as they have the 6 bolt pattern for the disk. In fact the same front wheel can be used for the CB750K, CB500K, CB550K, and GL1000 (possibly other Hondas w/6 bolt disc).Rear drum:
The rears are different between the 750 and 500/550. Inside the brake drum is a hub number. The hub number for the CB750K is 20200. The hub number for the CB500 series is 20100. Both came in either 16" or 18" with possibly a wide (3.00) 18" as well. The major differences in the two are the sprocket carriers. If you have the 20200 and want to use it on a CB500K then you need to get the sprocket carrier for the CB750K and vice versa.For the CB750FRear disk:
I am not sure if their were any changes in the hubs of the CB750F models. I think some models had a 530 chain (75-76) and some had a 630 chain (77-78)? Either way I believe the differences were in the sprocket carrier itself and not the hub. The Lester wheel for these bikes has a hub number of 20400. These came in either 16" or 18" with possibly a wide (3.00) 18" as well.Tube or Tubeless?
Lesters can be run tubeless. I know they don't have the bead retention grooves like modern tubeless rims do, but Lester marketed their later rims as tubeless and their seemed to be no change to the bead retention area. Some wheels will have a T or TL stamped into one of the spokes. The TL means tubeless and looks the same as the wheels only marked with a T.What do the stamped numbers and letters mean in the spokes?
Most Lesters have the size of the rim, the date the rim was made, and either a T or TL stamped into one of the spokes. I have never seen a Lester wheel with the part number stamped into the spokes, in fact I have never seen a Lester wheel with the part number stamped anywhere on the wheel. The part numbers were a variation on the hub numbers.
A typical stamp looks like this
T 19x2.15 TL DOT
