Probably not likely to find kdx/klx blinkers but later model ke front blinkers are identical to what we had fitted here in the 80's. The aftermarket ones are pretty shit.
These rear blinkers are right for our kdx/klx and are off a KLR. The ones I've bought with the short arms have come off the front. They're fitted over a few years & models and are also identical to look at to the originals fitted in the day.
The mounts need to be modded a bit to fit though.
Grind off the rubber dicks and take the thread down to the base and cut off the excess thread so it doesn't foul on the guard when mounted.
