I love the torque and reliability from these little motors and it will only be better and less shifting when I put the 351 jug on.

 

I love it, great vids and great data. Thank you so much.

IMHO, this further affirms my belief that the WR is NOT $1000 more bike than the KLX, at least in the power department. For $500 and some change you can get the full Muzzy and a better air filter, and some Kehlin jets, and the KLX will make comparable numbers to the WR. Plus you've got that other $500 in your pocket to better the bike in the other areas (tires, sprockets, etc).

I'm glad I went with the green machine. (or in your case, red )

 

Nice vid and results, jpaul, thanks for posting that.

Good explanation Neil. One thing I would add is that the reported HP is the peak HP of the curve, and as you said is related to torque and RPM. But peak HP is not necessarily peak torque, and is almost always not. Torque is usually dropping off when peak HP is reached.

Torque is pretty much what you feel as acceleration, so you can kind of think of it like that. I'd rather have a torquey bike in the lower RPMs than one that is less torquey in the low-mid range but makes higher peak HP, but that's just the way I ride most of the time. Peak HP may be more interesting to someone that rides their bike like a two stroke and keeps it throttled way up all the time and control the power with the clutch.

 

Have to agree for the money you spent on the KLX I see a 3.5hp diff, can see on the chart where he still pulls away from 65mph as thats where your hp takes a nose dive, I ride the trails mostly hardly ever see 65mph I'm looking for torque as in get to the bottom of a gully and the only way out is a 90% turn with no run, so for the extra $527 a 351 BB kit is the answer and I'll probably still be at or below the stock WR price. Good job.

 

Nice side by side post of both bkes on the same dyno. After reading all the posts about the wr on the adv site .... I thought the wr would have fared a little better.

The horsepower curve for the wr looked real solid and smooth thou...unlike the klx. I wonder how much a power commander and pipe help the wr .... I've read reports that it put up about 30 hp.....but looking at this dyno I find that hard to believe.

 

All dynos read different from what I've seen

But lets review. A KLX owner has to go through the trouble of buying all this stuff then spend God knows how long tinkering with it. Then rejetting in extreme weather changes, plus its a pain to do. And in the end (according to this chart) the WR is still 3+ HP ahead. 3+ HP is alot when your machine doesn't have that much HP to begin with. Your spending over $500+ just to get 2.5 HP. You do the match on the difference between costs on both bikes plus parts to equal HP gain its about right on the money.

Plus, lets not forget all the work is already done WR already..no messing. And if you do its, its already EFI...I mean come on. That is sweet. I know alot of people will try to rationalize a carb to make themselves feel better about their own machine but theres no getting around the fact that EFI is sweet.

 

Thanks Neil!

I was trying to compare the F800gs (84hp@7500 with 61ft*lb @5750rpm) to the F650GS (70hp@7000 with 55ft*lb @4500rpm).

A side tangent from the KLX but it fit well here. I have this curve:


I know the units are metric but the curve works just as well.
HP: They look about even until you get to 5500 RPM, the the 800 keeps going.
Torque: in lower RPM the 650 looks like it has the advantage. Then after 5500 rpm, the 800 keeps going.

I'm leaning towards the 650. (Mostly becuase the 800 is just a wee bit tall for my 32" inseem). Not that I am getting rid of the KLX, But the Shadow may get nudged out of the stable.

I am not a top speed kinda guy, all bikes are more fun on the bottom end for me... I like to play from 0 to 45mph, after that I'm just cruising agian. I dont think I get over 45 in the dirt, 35 seems fast. But that's just me.

 

Not sure about the rest, I'm with ya on the EFI, man, as long as it's done right. Not all EFI are created equal, though. From what I've read the KLX EFI is not so great, which is disappointing. Everything I've heard about the WR EFI says its pretty decent. Personally, I'd love it if my bike had EFI as long as it was done right and not ultra tame which sounds like what it is on the KLX. Apparently Husaberg got it dialed pretty good on the FE450, they commented on that specifically and good it was in the latest Dirt Rider review, I think they have several maps that can be switched in easily for different response, i.e., dry vs muddy, etc.

 

Good lord of course that's right Jason, but in 06 the wr did not exist..soooo here I am with a bored, piped and fcr carbed klx, could be worse thou.

If I were buying a 250 now....wr all the way, no question. Unless I wanted a dirt bike that was just street legal, then it would be ktm smoker.

 

Yeah, here's a rare occasion where we completely agree...scary huh?

I'd also add that the WR comes with a much better suspension and frame, so I think you get quite a bit more bike for the extra $1000.00.

For those among us who like to tour, the the WR's stator has close to twice the capacity of the KLX, so you can run heated gear to your heart's content.

Adding a big bore kit to the KLX will pretty much necessitate getting a more free flowing exhaust, so add those together and you have a few hundred dollars to play with at best. We haven't even touched the suspension yet.

I love my Kawi as much as the next guy, but I'm not gonna fool myself into thinking the KLX is better than the WR. If the WR were available 3 years ago, that's what I'd be riding right now...no question about it.
