Topic: Year Model of Forks

Restoring my CB750
Need some help to determine what Year Model of Forks these are as far as I know there from a CB750, I have seen some with holes in the bottom groove and some without.

[754]

They look like 73 -76 750 tubes, but i dont know the length off hand.. If they are, can be switched with 77/78 tubes that are plated all the way up.

Originally I purchased a rolling chasis serial number on the frame is CB750-2099507 but im not sure if the front end was the part assembled with that frame from the factory.

Rocky,

I just finished up putting my forks back together (1976 CB750 K6) and your tubes look similar to mine, except for the grunge toward the top.    So, I'd be inclined to agree with 754.

The Spring in the background of your picture looks real short.  New fork springs should be a little longer.  And it looks like your fork spring is a single rate spring, so it could be original, but likely needs replacing.

What do the parts inside the sliders look like?

Sorry I haven't been back sooner I have attached a photo of the internal part of the tube, would like to know if anyone knows what model front forks I have on this bike

As per my previous thread, I too would like to know. My 75 550k has two different length rods, one of which matches yours.

Rocky2010,
The parts you show in the picture look exactly like the internal parts on my 76 CB750 K6.
I'm just not sure on the length of the internal pipe, although it seems like it could be the same as my K6.

Maybe one of the guys that currently has their forks apart can measure theirs and confirm.

The part shown above should be just over 9", not including the bolt.
