I'd like to know how good the suspension on that thing is (some roads near me look like the Moon's surface), and I'm especially interested in the mileage it gets.

I'd like a WR, but the price tag is absurdly high - 7000, plated. A bit too much for commuting and the occasional offroad/goat path-like road excursion
why would you asume the bigbore out of the question just because you are EFI???
EFI should adjust fuel ratio by the wide band O2 sensor.
you don't nessesarilly need a bigger intake to utilize a big bore.
Think of this: 327ci chevy motor with 2 bbl carb. 454ci with 2 bbl carb
454 is faster and makes more torque even though it has the same 500 cfm carb. now take the 454 and cam it put a tunnel ram and 2X4750cfm holly's and you are makiing some serious power.
same but different.. Remember??? there is no replacement for displacement.

Well, you need to remember that we don't have that sort of gas guzzling cars over here. I assumed the EFI would take the big bore out of the picture due to my past experience with modded bikes, that required EFI tuning after engine modifications. Unless of course you would know of a product that would allow EFI changes for the KLX, which I do not know of.

Honda releases the CRF250L for sale in Asia. Complete specs here:

http://world.honda.com/news/2012/212...l/?r=m?from=fb

The listed curb weight is 315 lbs. If this is right, I will remove half my curse.

143 KG is still way more than my old XR600, but then again it didn't do 100 mpg...
I'm starting to like this new red piggy

315lbs is a lot better than 324lbs.

I wonder why the Aussie version (apparently) weighs 4kg more?

This is an improvement, for sure. Maybe the North American ones will drop another 4kg? That would do it for me.

With a two gallon tank, bring on the aftermarket. Why this over a wr250r at 300+lbs wet? Are there other benefits outside of it being Honda Reliable?

I was excited until I saw the weight. No point in getting a 250 that weighs the same as my DRZ400. I guess a WR250R/X is in my future.

Can't think of a single reason, aside from the obvious - price. And 'honda reliability' is not much of a selling point anymore either. Not when you look at the maintenance schedule and reliability of something like the WR.

I guess 2/3 the price of the WR and an alleged better mileage (see link above).

The biggest bang for the buck is the big bore and yes you can do it all by itself with awesome results.
The kit is $527 not $350
Im looking at picking up my friends KLX with the 351 kit, pumper carb, full exhaust.

What kind of mileage are you getting out of yours? He hasn't ridden it enough to really figure it out.

Runs on low octane and cheaper. I doubt it's more reliable than a wr250r.

I wished you were right on the "should" part - that's how I understood EFI. However bottom line is, I don't think anyone's gotten the 351 to run right with EFI though there are some guys in Thailand sharing info and getting real close. Off topic but if interested in how they are progressing they are somewhere on gt-riders.com

Lower price
Lower seat height
Choices are good

In the end the WR250R might be the better bike. We'll know soon, I hope.

This weight is troubling though. At 324lb, no F'in way. At 315, not likely interested. At 300, could be a contender.

At a tick over 300, the Husky 610 and KTM 640/625's are still considered pigs...


So a UJM 250 at 300?

There are no bikes that I know of that use a WIDE band O2 sensor and system.
They are all narrow band with limited adjustment range, and use maps for everything other then cruise.

Good systems seem to be able to adjust for small changes, the ones that have catalytic converters and intake pressure and air temp sensors (think Suzuki).
Other systems are quite crude and can not adjust for even small changes, and come super lean stock, think Harley Davidson.

A carbed engine can run a small or a big carb, its just jetted for the carb.
Since FI systems use maps mostly, and ignore the oxy sensor most of the time, a big bore kit would cause problems without changing the maps.
