Project CB690 (KTM 690 engine in a CB550f frame)

Fabricated the headlight ear/blinker bracket, and installed headlight shell. The front blinkers have an integrated white light, to compliment the integrated brake lights on the rear. So far I'm pretty happy with them.
I am not entirely sure I like the headlight where it is. The ears seem too narrow, and the headlight seems to project forward too much. Next I will fabricate a dash mount.

Impressive build...just came across your thread and have spent half the morning reading the whole thing!
Particularly interested as I had a similar idea a few years back.....classic styled big single ....and have now made several of them...

nice work. I recently picked up a 2015 690 enduro. I'm so impressed by the engineering and characteristics of these engines.

Thanks guys! Unclerob I really like how those turned out. Do they have a build thread?

Just a list of things to do on the bike.

  • Tank, including mounting, fuel lines, petcock, fuel tank vent, fuel level switch
  • Dash mount
  • Radiator fan mount
  • Sidestand switch mount
  • Exhaust mount
  • Rear brake master and pedal
  • Two more seat mounts
  • Steering stop and lock
That's about it, really. Then it should be a runner, and ready for the MOT.

Needed a muffler mount. The top pictures shows the bracket welded to the muffler, I'll open up one end of the slot so I can fit this threaded adapter in. I made the rectangle bit on the Haas. The counterbore chamfer will be tigged up and sanded flat.

Impressive! I've been planning a KTM-powered Cafe racer for years. Maby time so source parts:)

Installed the passenger pegs. They are a bit forward, which I thought would look better visually when they are in the stowed position. But, there is actually little room to allow for the passengers feet, they have a tendency to collide with the front riders feet. These may get moved.

Could you swap side left and right so when they are stowed they align with the tubes?

If you installed them as Doc said but right at the corner I think they would flip up and match the angle of the top part of the hoop almost perfectly. Instead of matching the angle of the main frame. That might look good and give you room for feet.

Hi Doc and Maritime,
I do like that idea, I may cut them off and weld them on as you say. That and I will beadblast and paint the footpeg bodies black for less visual impact.
