MT09 LED projector headlights

Hi all, I did do a forum search but didn’t find a topic on this specifically, but if I've missed it, mods pls merge, tnx...

For those that have a 2017 MT09 onwards with the “Optimus Prime” LED projector headlights, you may find, as I did, that they are pretty poor on low beam in unlit areas. Just want to let you know that adjusting them to a higher angle from the way they came from the factory made a big difference to mine, to the point where I felt comfortable up to 100 km/hr in unlit, rural areas, including around bends.

As you would see, if they are aimed too far down, the beam is a fairly narrow strip with a small vertical extent, causing the problem. I found when I adjusted them up the vertical dimension of the beam increased significantly, to the point where I was worried it might be too high... However, after an hour of night riding I didn’t get flashed once by annoyed oncoming cars, so must be OK..

The adjustment can only be reached by removing the four allen bolts on the small cover on top of the headlight assembly. The knurled knobs are NOT the adjusters - use the silver hex bolts with phillips head slots between the black knurled surrounds, screw them in to raise the beam... 10mm or 12mm spanner, I can’t remember... I do remember ending up using about two turns in from the factory setting. I suppose the two other hex bolts in the outer edges of the assembly are for left/right adjustment, I didn’t touch those...

Of course, I’ll have to adjust them again since getting the suspension tuned, as well as different springs (0.95 to 1.00 on the rear, 0.90 linear on the front instead of 0.95 “sort of” progressive) and damping we dropped the clamps slightly on the forks, so the bike will have a different stance from when I did it last... I’ll try to do the full story on the suspension mods shortly...

I’m guessing the Tracer doesn’t have this issue? At least, I’d hope not...

Must admit the Tracer headlights are brilliant from factory. I don't know why they fitted different lights to the MT when the Tracer's are so good to be honest.

It's a common problem with LED projectors though (in cars too), because LED doesn't have much 'bleed', so the cut off is very stark and makes you feel you can't see past that outline of light, whereas halogen has a diminishing edge which gives the feeling you can see farther. As you say raising them from factory setting will make a difference. Two cars I've had with LED projectors have both needed them tweaking very slightly up to get the beam just nice. Like you, I was worried they were too high but no-one flashes or seems to have a problem, so think it's all good :)

Indeed Otter, I also prefer the look of the Tracer headlights too... Oh well, I don’t look it in the eye when riding, so, yeah...

Guys & gals, sorry, got it the wrong way around in the above post, the knurled nuts are silver and the adjustment bolts are black. Doh!

Hey foureyes, have you tried the adjustment? It certainly had me down too (despite liking all else about the bike) but I now consider them “acceptable”....
