FYI I just purchased a Baja Designs Kit for my 2004 WR 450f. Baja Designs I decided to go with Baja Designs as I know that they've been around for quite a while. Also, I like how you can keep the stock headlight assembly because I am using the Acerbis Dual Sport Rally handguards with the signal lights built in (they are very low profile) Acerbis Handguards I was always interested in DSing my XR,DR but never got around to it.... 'til now. (with a WR no less! ) Once I paid my deposit at the Yamaha Dealer I ordered my Baja Kit. I found the Baja guys quite helpful. They are very willing to chat with you about whatever tech question you may have. When I ordered my kit they were being swamped with orders from all the guys in California rushing to D.S. their bikes as the new legislation was coming into effect. I was surprised that I got such good service. Ask to speak to Jeremy in the sales dept or Dan for Tech. info. They told me it would take 2 weeks to receive my kit I had it in a week and a half. I paid $345 (US) for the WR kit plus $8 for shipping, plus taxes and brokerage into Canada. I feel it's pricey but it is cheaper than buying TWO bikes right? I haven't installed the kit yet (it's still way to cold out there and my garage is not heated.) but the parts look well put together. I will not be using the signals that came with the kit. They are massive and although they are DOT lights I don't think that they do the WR justice.... I will be using K&S flushmounts on the rear. Flushmounts They are more low profile; they look better and will be less prone to damage. They are not DOT approved and I will take my chances (I won't be commuting to work on this bike ) The only thing that concerns me about the kit, or any of the kits available is that the headlight "may not be as bright as you like" ... is what the Baja guys told me. By the way, this goes for ANY of the kits not just Baja as I understand it. Last year Baja Designs was using a higher wattage headlight. I think he said it was a 55 watt. After receiving calls about burnt out regulators the Baja tech dept. decided to use a 35 watt headlight bulb to decrease the load to the regulator. He told me that Yamaha has wired the WR a little "screwy"... the regulator has been designed to put out BOTH AC and DC current which is not a conventional design for this type of bike (besides KTM ) Anyway, They told me that now they use the 35 watt bulb for the headlight and expect no problems. THE 35 WATT BULB STILL MEETS DOT REQUIREMENTS. Regardless of that, I asked what I need to do to use a higher wattage bulb (50/55 watt or more) and was told that they would need to rewind my stator which is a common task for a lot of other bikes. However, they have not done an WR450f yet so he couldn't tell me when or if they could do mine. I guess it takes a bit of electrical engineering. He said they are going to try to get going on the WR situation soon. (get on the phone guys!) If they could figure out the KTM's wiring issues they can surely figure out the WR. So for now, I'll ride with the 35 watt headlight I'm sure it'll be fine. Don't be wary of Baja Designs though; I researched all of the kits: UFO, Trick Dual Sport, Electrex/Dakar and Eline. The heart of the issue is the wiring on our WR. It may need a stator rewind. Nothing against Yamaha on this one they built a race bike not a street bike. Also, nothing against the other kits, I just liked the Baja because I didn't want to change my headlight assembly. The Baja Designs tech. (Dan) was the only one who could give me definite answers. I felt that he was quite honest with me while the other kits that i inquired about came with "you SHOULDN'T have any problems!" I will let everyone how my install goes and how it performs soon. I still can't believe that I'll soon have a street legal WR?????? This all may be old news to some but I haven't noticed any posts with detailed Dual Sport info for a while. Maybe this will help other new guys. I checked this site religiously to help me decide which bike to buy. This site has a wealth of knowledge. Hope this helps other riders Any questions?
