According to CMNSL, the part number for the CB350 handlebars change several times over the various iterations; to wit:

  • K0: 53100-286-010
  • K2: 53100-286-010
  • K3: 53100-286-010
  • K4: 53100-317-700
  • G: 53100-455-000

Predictably, I have a G and (per CMNSL) that part number is unique to the G. Are there any real-world differences between the various part numbers or is this just Honda changing suppliers or some other bit of bookkeeping?

I don't know the answer, but I go through that same thought process every time i'm looking for parts. It does seem that many times, even with multiple part numbers, the parts are interchangeable.

Probably just a slight difference in height and/or bend over the years. The G model may have a longer handgrip/control section to accommodate the brake master cylinder.

On a side note, I've noticed there is no 350 K1 model listed in any Honda literature. The '68 and '69 are both K0, and the '70 is a K2. People commonly refer to the '69 as a K1, though.

Re Honda parts codes:
First five digits specify the part (in this case, handlebars)
Middle triplet specifies the bike the part was ORIGINALLY designed to fit.... (G bars may be slightly different in bend angle so the master's reservoir sits level, or have a longer straight section at the ends so the master has room to fit)
Last sequence indicates iteration... (ie -000 is the original design, -001 may indicate a slight change, a different manufacturer/supplier, or a superseded part for whatever reason)
Letters following parts codes generally indicate paint color

Another one of those weird things they did back then... the K0 VIN was from 1000000 to 1020595, the K1 from 1020596, then the K2 at 2000000

Does the middle triplet remain constant across part numbers? If so, this would seem to imply that the '455' triplet would denote any part originally designed/manufactured for the CB350G, yes?

Doesn't always, as many parts cross over to another Honda - example I can immediately think of would be the early and later 450 middle numbers of 283 and 292, and some of the 283 parts fit all of them, hence Steve's reference to ORIGINALLY

Honda made many revisions over the years for productivity. They were trying to stay competitive and keep the bikes up to date. The parts may interchange but they are made differently, better or cheaper.

The four-hole rubber disc("packing"), part# 16955 268 020 that you find in the CB160 petcock assembly is also used in the CL72-77 and the early GL1000. The product code number(268) is for the CB72.

No.... The BIKE CODE for the 350G is actually -344-, SO, any part with that 344 triplet was SPECIFIC (originally) to the 350G, (and WILL fit your bike), but MAY have also been used on other models or variants (for instance, the "euro" version, or Japanese domestic version, as opposed to US model) at a later date.... I'm sure the G model also has MANY -287- and -317- middle triplet parts from the earlier "K" CB-350 models as well......
