Your headlight setup is pretty similar to mine except I went with the rigid dually LED lights, basically the same price. With my setup I haven't found a situation where I can outrun the lighting. Btw, my buddy just bought the same bike yesterday and I'm trying to talk him into doing RWV.

I plan to use it for RallyWV so much more light is needed.

The stock stator has a 35W DC circuit for battery maintenance and then a 55W AC circuit runs the headlight (35W/35W BA20D – bastard Euro bulb that barely lights the front fender) and tail light (1157 dual filament). The aftermarket fan kit runs off the battery but it is thermostat controlled and hardly ever runs so impact there is minimal.
Stator

The upgrade options are covered pretty well here: http://www.spokanister.net/ktm_stator.htm
These are the options:
1-Modify the stock stator to DC and get a regulator/rectifier to handle the additional power $65
2-Buy a rewound stator and reg/rec. $145
3-Buy a 3-phase stator and reg/rec. good for 250W peak output...for $240

If you researched race lighting options you’ll see there are some sweet LED lights on the market now. I’ve watched this for a while and the latest generation can pump out around 100 lumens per watt when driven hard so I decide to move into the modern age with some High Power LED lights. HID setups are nice but I like the LED idea.
Baja Designs has their Squadron light that uses high power LEDs, Clearwater Lights has the Krista, Cyclops has the Sterilizer(awesome name), Rigid has the Dually and other light bars….. but all these are between $350 and $700 items. The electronics design, optimization of optics, and thermal management design are not trivial with high output LEDs. The price reflects the fact that these are new to the market and the non-recurring design cost gets passed on to the early buyers.
I’m a tight a$$ so I did some searching and ended up going to ebay for two of these no-name Quad-Cree XM-L lights for $180 shipped.


LEDs won't work with DC and the stock power wasn't sufficient anyway. I got the 3-phase stator and reg/rec kit shipped from Accel for $118. They can be found on amazon and a few other stores. The part number is 152450.


The stock system had AC running directly from the stator to the lights so I had make all that circuit DC. The bike is now fully DC with power to spare!!

The bike already had a headlight switch and fuse which I now use on the 8” light. I also wired up the switch that came with the LED light separately so I can run them on their own or with the 8” light.



Here’s a “before“ pic with the stock light. Yes it really is that useless. Doesn't even show up 10ft from the bike. I manually set the exposure so all the pictures are taken on the same settings. The lights to the right are in my neighbor’s yard about 160ft away. The center of the road at the end of my driveway is 120ft.


Here’s the 8” light nice tight pattern. When it’s pointed down low nobody flashes their brights.


Here’s the 8” plus the 2 LED lights. The hot spot of the 8” is barely visible. I still have to figure out where I want to aim them for best effect. It really depends on terrain and speed.


I’m super impressed by the output on these. Now that I’ve seen what they can do I may work on a custom LED array for the stock headlight housing when I throw it back on for woods riding. The big trail tech light may not be needed any more.

Different LEDs put out light differently and have their own sets of lenses that have different output angles (spot vs flood). These are supposed to be about 25 degrees but they have a lot of spill outside the center hot spot. I’ll be experimenting with different setups with the bare LEDs I have on order.
I’ll post some updates once I ride more with the new setup and see how it all performs.

Hope this helps motivate some tinkering or sparks some ideas!!

Thanks for the write up. That is amazing, I can't imagine having that much light during a night stage. I've just been pinning it and sort of hoping for the best every race, haha. Definitely has the wheels turning...pun intended

I agree....can't imagine how fast she'll be with the new low drag setup

I agree. Went out to Perry State Forest for some trail over the weekend. It's definitely a heavy feel swinging that thing back and forth in the woods. I knew it would be from riding the DRZ on single track with the that heavy mother.

As an update on the LEDs...I got to test the waterproof nature ...what looked like a 4" deep puddle was a bottomless pit of rotting mud. I wear a camera just to catch me being epic-ly dumb...



Note: If your headlights are under the mud....you're doing it wrong.

that's one nice mud hole! Hope you are OK after that get-off.

When I first mounted my 8" light I had to ride the bike 60 miles home from the shop, it felt so unstable and twitchy. I guess I've just gotten used to it because the bike feels great now. I hope I can finish all of the stuff I have planned for my bike before the race.

I'm fine. I cleared the bars entirely and the landing was soft. I'm calling it the superman dismount.

Actually I cut the video just after I got the bike upright but directly after that I fell over getting myself out of the mudhole so all you see is me laying on the ground laughing at the whole mess while my buddies come over to laugh at me and take pictures.

Thanks Bruno!! I almost want to race the DRZ instead because the clutch was slipping like mad at SandBlast and I know it's got some more speed in it(even it if I don't). Now that I have that fixed I think it needs some redemption.

Are you coming to WV?

I'm having a tough time deciding if I should race the Super Enduro at RWV or not. If work isnt to crazy, I'll join you folks

You gotta come and make up for the 690 letting you down last year!

Yea, that's part of it but I'm more concerned with the Rally itself. If all the pie in the sky claims come true, it will be a great event. Now that Dick Paddock is helping with the event, I'm sure he'll do all he can. I'll be a last minute entry if at all...(Cue Jeopardy theme)
