Reproduction Honda throttle / starter / kill switch assembly for the CB450 from 1971-1972. It's common for the starter button's on these bikes to wear out due to arcing or 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 single pull throttle cable. Not push pull.

If you are running aftermarket handlebars check to make sure the 29.5" wire harness is long enough. There is a locator pin built into the switch, just like the stock ones, if you're running aftermarket handlebars you'll need to remove the pin or you can drill a hole in your bars for the pin to fit into. Also note that these switches are made for use with stock bars where the wring runs through holes in the bars.

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 29.5" long.
  • 6 Male Bullet connectors - yellow/red line, 2 black, brown/white line, white, blue
  • 1 Female Bullet connector - black/white line.

Replaces Honda Part Number: 35300-319-670

Note: This switch has a total of 7 wires, some of the stock switches had 9 wires. There is a solid yellow wire and a white/yellow stripe wire that isn't part of this switch.

Fits Honda:

CB450K Super Sport - 1971-1972

and can be used on many other bikes.

    Right hand throttle switch

    Posted by Shaun on 1st Apr 2023

    The fit was perfect for my CB450. It has 2 fewer wires than my original so I had to think about what was getting hooked up in the headlight, but it was straightforward. With fewer wires, it was easier to slide the harness into the handlebar. (With a little spray of armor all). I would definitely recommend this product.

    My factory switch was no longer functioning. This assembly was a perfect fit and match.

    Great product

    Posted by David B on 11th Oct 2019

    I’ve used this switch a few times and also the turn signal/horn switches they offer and I’m very pleased. Great fit, look authentic and are very affordable . I had to adapt by grinding out a groove in the bottom half as my 72 CL350 had external handlebar wires. This is designed for internal bar wiring. It worked great with no alterations on my 70 CB350
