good post idea! I'd like to see some trikes in there like tri-z's and tecates. Those must be close to the top of the list.

 

thanks for the comments guys, keep'em coming... I'm still correcting and refining this list as I go

 

ltracerx is correct of all the 250's the tecate has the most horsepower and is the lightest of the bunch and then the lt 250r and then the 250RT has the least amount of power.of all the actual dyno tests that i've witnessed ,a fresh piped 250r only puts 28 hp to the ground and i seen my very own bone stock completely original tecate with the opriginal piston and rings after 11 years in storage put down 34 hp to the rear.
but as far as other machines go i'm not sure and can't really give any numbers as i don't pay much attention to the others.
the real way to figure these numbers is actual horsepower from the crank and then figure horsepower to wieght ratios.
and if you go that way then i can tell you that a tecate 4 had 42 hp ,lt250 38 and the coveted 250R has 33hp.
figure your power to wieght ratio with actual horsepower figures instead of rear whell power,oh and the banshee 's only have 33-35 hp.

 

I'm just wondering how you got the numbers for the Suzuki Z400 and the Kawasaki X400. The quads aren't even in production yet. Quads tend to lose a little more horsepower than bikes with equivilent engines.

Also, the numbers for the Polaris quads seem a little high, but they might not be if they were run on a proper dyno (one that will take CVT machines). The last I heard, they would make about 28 or so horsepower at the rear wheels (36 for the 400 / 38 for the 500 at the crankshaft) on a dyno set up for manual transmissions.

This would seem to justify what I've said all along about the difference between sport quads and high performance quads. The differences are in the power to weight ratios. Numbers 1-10 are what I would consder "high performance machines". Numbers 11-19 I would cnsider "sport machines". I tend to go by the much clearer pounds per horsepower, but this is a valid approach. May I suggest that we all agree on the number .0775 as the baseline for the "high performance" machines and that anything that falls below that is considered a "sport" machine?

 

The 1986 250R weighs 328 pounds, I'm reading that directly from my owners manual. The '88 and '89 will weigh even less due to the aluminum swingarm's for those years.

 

Thier aint no way a stock Banshee is makin more hp than a Raptor. A stock banshee has to be in the 33 hp range and the 250R's more in the 30 range.Also I have heard rear wheel dynos of a stock DS 650 in the 41-42 range. And how does a 250r weigh almost the same as a blaster? Also why isnt thier a regular DS 650 in the line up. They weigh about 20 pounds less than the baja. And are faster because of it.

 

Your HP numbers in current form look pretty close...

The Quadzilla is a little high I think, never seen any real dyno's but seen enought of them run that 51hp sounds REALLY high.
Cannibal is close - up to almost 45hp on the higher end models like the Moto
The stock Banshee is closer to 34 or so
250R class quads are on
Raptor is on
Z400 is probably very close if not a tad high
DS650 is low, I've seen closer to 42
400EX is a bit high - usually 27 is a pretty safe number for a stocker
Sport400 seems a tad high
Scrambler 500 seems way high - mid to upper 20's is more appropriate
Warrior is a bit high
the 250X is probably a little low

 

Thanks for the clarification on the 250 racers, KillerKX. I thought those HP numbers on those quads were off. In fact, I friend of mine with an R told me just last Sunday that the "official" stock rwHP was 28. I have a C-dale brochure that says the Cannibal puts out 33HP at the Rear wheel weighing 380 lbs. (.0868) and the "great" Raptor w/ 28HP at 420 lbs. (.0667...yuck!) and the 400ex w/ 21hp at 389 (.0540...and another yuck!)

By the way, DSAPP... where did you get these numbers??? A lot them are not what I've read or heard. The above figures I wrote, for instance, are from CANNONDALE, themselves. Why would THEY undercut the HP in their own brochure after using a "Superflow Cycledyn Dynometer" at their very own factory?????

and lastly, Yodaddy, WHAT THE HELL ARE READING?????!!!!! I looked long and hard for the numbers in your little rebuttal and still don't see where you got them.

And it's totally normal for the 2 strokers to put out more ponies than thumpers twice their size...not to mention the superior weight ratios, BadBombardier. 2 strokers haven't faded out of production for lack of power...quite the opposite along with emissions issues. I think the constant puming up and touting of 4 strokers (and ignoring of 2 strokers) by today's mags is starting to work!!!

 

1986atc250R,

Are you sure the C-dale moto does 45HP?? I was under the impression that aside from the rev-limiter and hydralic clutch, the cannibal had the same motor as the other 3. The improvements over the cannibal by the other 3, I thought, were in chassis and suspension upgrades.

 

Dsapp,

I pulled out my May '88 issue of 3&4 Wheel Action for the 250 High Performance shootout. The factory dry weights are as follows: TRX 250R 339.6 lbs, KXF 250 Tecate 4 328 lbs and LT250R Quadracer 325 lbs. Then again, the 87 TRX 250R dry weight, according to 3&4 Wheel action is 328 lbs...but that model was slightly altered in 88 so who knows for sure!
