Reproduction throttle / starter / kill switch assembly for the Honda CB550K0 1974 and CB750K 1973-1974. It's common for the starter button's on these bikes to wear out due to arcing or they can break for various reasons. This is an easy part to replace if your wires aren't running through the handlebars, if they are, it requires removing the handlebars and feeding the wires through. Electric start sure is nice to have when it's reliable!

This is for use with a push pull throttle set up (you can just run a pull cable if you want). We also carry the left side switch assembly here.

If you are running aftermarket handlebars check to make sure the 24.5" wire harness is long enough. There isn't a locator pin built into the switch like the stock ones, but there is a hole in the switch that will accept the stock locator pin which keeps the assembly in place.

This switch assembly will fit on many of the Honda CB's, check your wiring harness and make sure the connectors will work or you can replace the bullet connectors with connectors that match your harness. This switch is handy to have since you can turn the lights off to save on power consumption during daytime riding.

  • Wire harness is 24.5" long. (measured to the end of the shortest wire)
  • 5 Male Bullet connectors - yellow/red line, 1 black, brown/white line, green/red line, black/red line
  • 1 Female Bullet connector - black/white line.

Replaces Honda Part Number: 35300-341-671

Note: This switch has a total of 6 wires.

Fits Honda:

CB550K - 1974
CB750K - 1973-1974

and can be used on many other bikes.

    Great right switch replacement

    Posted by James G Merrill on 23rd Jun 2018

    CB750 K3 needed new right switch. Only one wire was a mismatch from the harness, but no problem to figure it out in the headlight bucket. Works great and looks great, and threading cable through handle bars went much more easily than pulling old stiff ones out. It looks so good now I feel like I should replace the left switch.

    No High Beam

    Posted by Unknown on 19th Apr 2018

    It's a great replacement product, but be careful to get the correct one! I didn't realize until after I mounted this that the light switch didn't have the high beam setting and wire. Only an on/off switch. There is a different throttle switch assembly available that has the 3 light settings. Be sure to get the correct one depending on what you are replacing! Just because they say it's "compatible" for your bike doesn't mean it's the right one.

    Mistake turned to acceptance

    Posted by Michael Townley on 9th Apr 2018

    Generally I don’t like returning parts. When I realized I made a mistake and purchased a K series switch instead of the F series bike that I have, I decided I would just make it work. Wiring colors didn’t coordinate well with my bike but that’s nothing more than figuring out the different circuits in the assembly and how I could make it work on my bike. Aside from my mistake, the switch feels like a very nice product. Fit and finish is OE quality and much cheaper than an original switch. This was a nice compromise between original switches and cheapo ebay switches.
