The frame is identical to the 2012 yz250f according to Yamaha.

Not quite "exactly" the same. The rear triangle is different for the WR to make room for the air filter and battery. If you look at the one of the sides of the frame, left I think, you will see where the mounting point is for the YZ250F, the tapped hole. Whereas the WR has a tab welded to the frame.

[Supermega1] The Comp ECU preloaded map is flat, all zeros. I found that out by "downloading" it from the ECU after I installed it. I just plugged in one of the basic maps on the sheet that comes with the ECU. one of the things I think is nice about the programmer is that you can store up to 9 preset maps.

Yeah I checked that with the programmer when I installed mine. But I am 99% sure its different (besides dirt rider said so ). From the things I've read to my experience with it after installing it. Just because its reading "zeros" in the programmer doesn't mean the default values that are programmed in the COMP ECU aren't different then the ones in the Stock ECU. Its just reading the new values as "zero" values or as the default values for the new ECU. Not to mention those "zeros" only represent "Fuel" and "Ignition" which are the only variables that can be changed in the ecu. The ecu has variables probably for at least 10 other things in it that are not adjustable which means they could be different from the stock ecu to the comp ecu.

When the bike was completely stock you could barely fire it up first try. Idle was lumpy and it was hesitant to rev loaded/unload
Pop the comp ECU in and it fires up first try every time, idle was smooth, and there was no hesitation to rev loaded/unloaded

That is without changing anything other then the ECU.

That is the subframe not the frame.

So I just filled my tank back up and it took just less than 1.5 gallons to fill it back up. So to recap.....fuel light came on around 35 miles, I drove it 46 miles, and still had approximately 1/4 tank of fuel. That means it was getting about 30 mpg and should get around 60 miles to a tank. That was with the comp Ecu, map for the stock can with woods map, PMB exhaust insert, and a combo of moderately aggressive desert and highway riding.


That seems a little high but, I will take it all day if it is repeatable. YMMV.

Sorry for my bad English! Just want to express that the bike can run like crazy when twisting the throttle, but when ease off the throttle it hiccup.
So, anybody has the map that can works for Dr.D pipe? This is the very first 2012WR450 in here, and we have no dealer who can help set it up.

Thats OK.Your English is better than our Vietnamese.Your buddy needs to get the competition ECU that also comes with a shorter throttle stop screw and the YZ Power Tuner.The ECU comes with some baseline maps, The FMF exhaust map would probably be a good starting point for him. He is running premium fuel in it right?

Thanks for the advice!
The Comp. ECU and Power Tuner was ordered. We often use A95 gasoline, that's the best we can have here.

Has anyone noticed that the swingarm is from the 2011 WR? I don't understand why they would take a 2012 YZ250F frame and put a 450F engine in it and then take the cool new swingarm off, which is supposed to be lighter and flex better, and put old technology on that new frame? Is this new model just a strategy to get rid of some left over swingarms, engines and frames? The engine design is ancient, except for the FI. And the weight is over the top. I know some of you will never get the whole weight issue but my WR250 was 220lbs dry after spending lots of bucks on making it lighter and it felt really heavy. This thing is what 270lbs??? Do they really think that Whibbs is going to race one of these? Not unless they build a one-off 220 lb version just for him.

Yamaha could build the best off road bike in existence if they wanted to.

They don't. All they are concerned with is profits.They have lost touch with the passion of motorcycles. Hate to diss them, I ride and own nothing but yamahas, but its just nuts. It's almost as if American politicians have taken over Yamaha.

BTW - You guys who bought the 2012 WR450F, I'm just jealous. It really does look cool and I'll bet it's great in the woods. I wouldn't buy one to race, but for fun, it's probably one of the best. You could ride it, wash it and ride it again many times over before having to do any serious maintenance.

I agree. The same as taking six years to finally put the SSS fork on it. Like no shite, took 6 yrs to finally make that connection??? Really? Had that many open bath forks to get rid of?

Hydraulic clutch??? Why isn't this standard? What about the Auto Clutch?? Think they know how to do that after 30 yrs of quad trannys? Street Legal?

It's almost as if they don't really want to sell a bunch of bikes........

Build it and they will come.
