Keeps the costs low - or not. Wonder why they use the dated swingarm though? :)


I don't see why they didn't just make a subframe to fit. It would work. :)

This is the comparison from the Canadian site for the 2011 and 2012 WR

http://www.yamaha-mo...2=3869&model3=


I'm a little concerned over the inch plus drop in ground clearance. I realize this is also a function of suspension settings, but the '07-'11 WR was soft and had more GC. With the change to the 250f frame I was hoping for something closer to the 15" that bike has.

Ground clearance is key for off road. It's prolly the tall motor of the 450 stuffed into the 250F frame therefore they had to lengthen the engine compartment. :)

What is the earliest date this bike will be available? Does anyone know? I will need to get one of the first.

Ground clearance specs, just like suspension specs, are not measured the same from bike to bike or brand to brand, and are usually meaningless unless you measure them with the correct spring rate, at static sag height.

mauricedorris, What I'm saying is that EFI has just as many, maybe even more, issues than the "thing of the past" carb. I'm willing to bet that the new WR would run even stronger, and smoother with a carb installed over that EFI. Just my opinion, that's all it is. Maniac

Cuz they got em in the parts bin...........Not nocking the thing, but it is pretty evident, with the exception of fuel injection developed for the existing engine, and some updated plastics. It truly is a very budget oriented evolution. The bike appears to use most of what Yamaha has been producing for years on not only the Wr series, but on YZ models. Sheer weight has always been this bikes biggest enemy. Looks as though Yamaha did little to address that issue. It's really a shame these bikes are so dam heavy. If this bike did actually GAIN weight, that is inexcuseable on their part.:smashpc:

I understand their need to economize. Fewer and fewer units will sell in this economy and their supply line has been disrupted to say the least.

I have heard of very few problems with FI. Therefore I assume its good. You probably are aware of more issues than I am.

I know on my KTM, I thoroughly dislike changing jets. The guy riding with me on the Husaberg hits the start button, no matter where we ride, and his bike fires right up. It runs without coughing or spitting or bogging.

After a couple of adjustments, I did get it right. But I definitely look forward to not having to mess with the carb again.

I guess a part of me wants to believe the hype.

FI>carb, that's why all modern cars have it. It's the logical progression of things.

-What about the pump filter not being replaceable?
-What about the fuel nozzle not being cleanable with compressed air or a wire 'hair'?
-What about a fuel pump that will fry itself if you run out of gas?
-What about a fuel pump that was never designed, made, or produced for off-road use, and will (and has) self destructed in hard racing?
- What about a fuel pump and BF and nozzle assembly that gets replaced after every moto in SX and MX racing, unlike and FCR that can go 5 races?
-What about having to use a fuel 'sock' in the gas tank to keep dirt out, even if you gas has been filtered?
- What about if you loose pressure in the pump nozzle, and you have to repressurize it with a tool that no dealer has in stock?

You mean all those great things about FI, or all the other ones!

You have to keep messing with the carb, because you never finished jetting it correctly.

My KX starts first kick. Needs 4 four slow and one fast to re start if dropped.
My CRFX starts first button push. Needs hot start to re-start
My WR starts first button push. Does not need hot start to re-start
All are FCR carbs with R&D powerbowl II and full Kehien brand re-jets (No JD jets or needles).
None have been FA mix tested, but I would love to do that......

Its as if they asked a real offroad rider, what parts of existing yzf's would you chose to put together and build the ultimate offroad yamaha. None of the parts are new, all tried and true! I couldnt have done it better myself! Cant wait to ride one!!!!:smashpc:

Exactly what Krannie said! Ask Ryan Dungy if he's had any issues with his "EFI". Well, on second thought, don't ask him. He's too polite to tell you the truth about his "issue" in Texas.

Simple fact: What's the # 1 component on a M/C that fails?
Answer: Electrical components

Maybe I'm finally becoming an old fart that just hates Technology! But when I'm running down in Baja this winter, I don't want to be doing it on any bike that doesn't have a carb!!!

CARBS DON'T BREAK!!!

Everything that you are describing sounds more like poor design and poor quality. Don't confuse a poorly built product with a vastly supperior technology.

I'm just waiting to see some specs (weight in particular) on the bike, and for them to appear in person at the dealership for a close up inspection, to make a final buy/blow it off decision.
It's main competition as of now is the KTM 450XC-W, which is what I'll be comparing it with. At the moment, the WR is $1200 in the lead.

Saying "Vastly superior technology" is the same as saying "my idea is better than yours".

It means nothing until it is proven.

Currently, FI has PROVEN itself to be a better performer, easier to tune, faster to tune, but ONLY FOR A SHORT PERIOD OF TIME, and then it requires additional maintenance, or replacement.

More often than a carb by a factor of at least 25 to 50.

FI will eventually catch up with carbs in reliability, probably in the next 3 to 4 generations.

Until then, I refuse to be a Beta Tester for a 'vastly superior technology' that is impractical and high maintenance in an off-road environment. MX is different. You can see your truck from the track!

Here's a list of 'vastly superior technology' that took a looooong time to be perfected:

- 21" front wheel: went from 18, to 19, to 20, to 21, to 23, then back to 21.
- long travel suspension: this could take up books with the 'technology improvements' that lasted about 45 minutes until breaking. 1972 till about 1979 until it was superior for the trail rider.
- Reed valves: that took about 5 generations
- Aluminum frames: still inferior and heavier, but cheaper to make.
- blah blah blah
