Turbo WR250R

Why would you need to weight the back of the bike to pull a wheelie when you have a 650 engine and a turbo that supposedly gives 75% extra horsepower? I normally see the boys that struggle to wheelie 250’s pull that sort of trick

It certainly is different

If you could do a good wheelie you would know that you sit at the back of the bike when you do the wheelie, look around, you do it, rethink it, its for control, lowers the centre of gravity making it easier to control remember your 4th gear Wauchope wheelie, you would have been sitting down the back :blink:

DOH!

Thanks TB. You confirmed my point though. I sit on the bike. I don’t stick my leg down the rear mudguard to unweight the front wheel even more so that I can do one. That’s what you do if you struggle for power to get the front wheel off the ground. My point is, as mentioned in previous post, why would you need to do that on a turbo’d XR650?

You could sit on the handlebars and be cracking wheelies on that bike. If an XR has 60hp and the turbo gives him 75% more power then he has 105hp to play with on something that weighs 140Kg.

Maybe that’s what I’m doing wrong with my wheelies. I’m 55hp short and I don’t dangle my leg off the back. I’m surprised that even you have stooped to defending a poor wheelie technique just because the dude is riding an XR. And everyone says KTM riders are the defensive ones….

I am finding it very hard to believe that a single cylinder “lugger” with a long(ish) stroke and great whopping slug, relatively low revving, with no extra cylinders to help smooth the power pulses out and so forth is capable of 105 real neighing neddies without continuous breakage, how would the gearbox stand up to it, the frame, the output shaft?

I also don’t really believe a stock 650 puts out 60 hp, masses of low and midrange torque yeah, but 60 RWHP that’s pretty impressive for a heavy valve trained, long stroke, no gizmos single cylinder.

not dissing the Xr650, is a mighty bike fer sure, but honda must have hit on a magic formula that the old “sound of Singles” lads with massive cams and years of development on already stressed motors never stumbled upon.

a 530 hell even a big husky 610 or whatever they are this month.
The Big HUSKY isnt a huge power house..It holds some serious torque but its a slow revver,likes to take a bit of time to wind up. can be Snappy up high if you wish it to be, All up its a rather ” relaxed animal”. certainly wouldnt consider a Turbo for it though..it’s way heavy enough already. Want “power” i reckon the 510 or the big 530 ktm would be more than enough…Imho…

From here on i will never question or ask or wonder about a thing you say write or do Moto, I also now see you dont like to be questioned or made fun or your posts , you have now become my authority on everything but always have been. I was only speaking of wheelstands in general, which is why I mentioned your wheelie at wauchope which is why I spoke about sitting position, sorry I thought I was helping , but you would know that , sorry my bad

Mr Blue, you are correct a stock XR650 does not produce 60HP, mine only produces 63 and has a lot of work done to it (measured at the rear wheel) Check this figures with Steve. Gearboxes would be the issue I think with the wheel slipping and then grabbing traction again, its a problem desert racing with all 450’s as the gearbox size is small compared to the hp the engines are capable of which is why cushion drive hubs are used.

Ta TB, that’s what I thought, the KLX650 is another example of a good alrounder that some folks have a passion for as well, and i reckoned Honda would’ve been insane to release a highly stressed Hi-Po thumper into the “adventure” market, cause those laddies want Africa on one oil change, not Johannesburg on a engine rebuild.

I always view HP figures cynically, remember the old streetbike Horsepower shootouts in the 90s? my worked GSXR11 won the North coast region for two years running in both top classes with only 152 RWHP on a humid day and a very linear torque curve, yet a stock ZZR was supposed to have 160-170 according to the press statements, yet the old girl annilliated all comers with supposed huge HP outputs, was only bested by the huge $$$ metro turbo & NOS bikes.

Monos are an individual thing POB (point of balance is different for different techniques and riders, low speed I am almost sitting on the rear guard, arms straight, body at right angles to bike, higher speed I am much more forward as I am using power more, standing I am crouched at speed to avoid “quick flip”

Cant speak about Monos mate, but as far as the hp figures go we sometime rush load engines on the dyno to get a hp spike (it will be higher than real hp) as such to comfort a whinging truck driver, if he believes it is higher he thinks it goes better ! :blink:

I wouldnt believe the figures about mine but I have proof, interesting the drop in hp of a current high performance 450s and 250s 4 strokes when they warm up and get hot incredible the loss in hp. People dont related torque to performance enough, plus a bigger four stroke doesnt rev as quickly (any brand) so it may seem as though it isn’t as powerful as we know

as we both know TB H/P or PS is only a by product of torque, a torquy engine with well sorted gear ratios will always feel slower, but across the quarter or hillclimb events will easily match the screamers, particularly where sharp cornering and getting power down is concerned. The boyz in north Qld years ago used to build “junk” 308s with whatever pistons etc they could get, no staic or dynamic balancing, no blueprinting, no trick head work, just a well sorted intake, cam, and exhaust set for linear torque output and a stock redline, tri-matic and 10 bolt in a higher ratio and could get down to 11s’ in a kingy besting 450-550 hp clevelands and chevs.

we built one and put it in a LX torana and it was lethal, for an outlay of $1200 in bits from the wreckers and the cam, manifold and carb.

I try to take the same integrated approach with all my vehicles, for example my mild modded V6 Rodeo will easily outrun a SV6 to 140-150 klicks, now i just gotta find a new diff with the right ratio that fits under the bitch to complete the package.

:laugh:

I said 60HP as I’ve other other people over the years say that’s what they generate. The figueres were always meant to be taken with a pinch of salt. Also, who believs they are getting 75% more power. I sure as hell don’t.

I agree with Bruce, I reckon reliability would be a massive issue and it would run for all of 10 minutes flat chat before it stripped gears or melted a piston.

I went fishing and caught me a big fish

HMMMMMMM.:side:
this thread is gettin a bit serious, and we cant have that!!!!

my mental radio is playing simon and garfunkel at the moment…
MrBlue has inspired me….

the sound of singles……by simmo, giraffe uncle and menace

Hello Kato, my old friend,
Ive come to roost with you again,
The hondas 60 horses softly creeping,
Took TBs knobs off while he was sleeping,
The torque curves MrBlue has planted in my brain
Still remain
They show the sound of…..singles.

In restless dreams I roost alone
Through Champos lanes of cobblestone,
With the warmth of his free jacket,
Moto turns his collar to the cold and damp
One day my arse were stabbed by the flash of
An Orange gun
That split the bum
Now ive felt the sound….. of singles.

And on the OBT forum I saw
Ten thousand XRs, maybe more.
Moto talking without speaking,
Moto hearing without listening,
Menace writing songs that voices never share
And no one cares,
For his song, about the sound…..of singles.

Fools said i, you do not know
My 2 stroke like a cancer grows.
Feel the power and it will teach,
My arms are streched now i can reach.
i admit that i love the sweet scent of castor oil,
And muddy soil,
They are the smells…. of singles.

And all the old bulls bowed and prayed
To the new XR Mick had made.
Chops banana flashed out its warning,
the next day we were all in mourning.
And the signs said, turn left at alberqueque
And stop to eat beef jerky
And taste the sound…..of singles

Sometimes we ride into a big ditch
Like mick did on his Big Red Bitch
And after jumping all the erosion mounds
We all feel like we’ve just gone ten rounds
And when your Yamaha wont start in the middle of a single track
drink from your camelbak.
And hear the ever…….

distant sounds……of singles:kiss:

Unbelievable, you are a unit, a unit with a talent

karma for that and my hat of to you my friend

i wish i was a unit with talent for ridin mate..:silly:
