This is one you probably haven't heard before -- I am going to set up
my just-restored 86 CR500 as a 1/8 mile drag bike (at a commercial
asphalt strip near here). Not even ridden since the restore, it has
an FMF pipe and the Boyesen Rad Valve installed. In the class it would
run they have everything from BMW bikes to snowmobiles with rollers and
shifter go-karts!

I did finally get the bike started after some help from the group (had
to straighten a dip in the fuel line and back out the pilot screw to 2
turns with choke off-- now it starts like a moped but doesn't sound
like one).

Does anyone have the slightest idea what kind of ET or trap speed it
would do (I weigh 160)? The closest set up I have seen to this is
the TT/SuperMotard bikes (http://supertt.com) and CR500 road racers a
few years ago.

Ideally I would like to find a used front and rear hub to lace up to
17, 18 , or 19" rims with steet tires permanently mounted and keep the
current wheels for off-road games. Apparently the 85-86 CRs all shared
at least the front hub, judging by the common rotor. Let me know if
you know of any for sale. The rear hub is, of course, a drum brake unit
from that period.

Any other helpful suggestions other than that's crazy I would be
interested to hear...

RR reckons they'll do low 10's on the quarter (search Deja) but I don't know
how that would convert to 1/8ths...

an aussie magazine measured one at 2.8 seconds 0-100

only other rumour is that the trannies can't take ashpalt launch's very
well...

also you'll probably want to run wheelie bars if it rides anything like
mine!

shit! you are one day too late. I just this morning took what was
left of my 85 CR500 to the dump, including both front and rear hubs...

Haven drag raced a Kawi 500 H-1 triple 2 stroke and a Kawi Z1R bored to 1300cc
for a few years, I have to raise the BS flag real high on the CR5 doing 10 sec
1/4's . In the 1/8th, my Z1R would run 6.5sec and the Triple would run 7.5sec.
I was an average rider with good reaction times though they don't matter. A
friend with a more then adequately modified Yamaha RD400 could not touch the
500 no matter who he let try and beat it. Come on, 10 sec. in the 1/4 on a
single cylinder, That is about 130mph. The national record is 7.2 at 195 on a
Pro Stock drag bike.

I would guess a low to mid 9 sec range in the 1/8th.Depending on the start you
could possibly get into the 8's.Most 600cc sportbikes with avg talent can get a
low 8 in the 1/8th.Of course there are exceptions to the rule...A high 8 sec
1/8th would roughly translate out into the high 13 sec range. To get below 9
secs in the 1/8th you will need to be running better then 77-78 mph.

Nope. chassis CR500's drop ALL the stock street bikes at our drags, they
make R1's look like R0.5's!!

even a stock CR500 in it's standard MX chassis with knobbies will outrun a
600 streetbike, it's got way more torque (+20%) and nearly half the
weight......

not many 600's will throttle wheelstand at 80mph like CR500's do!

Bob those are 70's/80's engine designs,if you know anything about the CR5 it
has an awesome reputatioon for making power & torque.....absolutely NOTHING
like a heavy H-1 or Z1R engine. And comparing to an RD400???

If CR5's can do 0-60mph in 2.8s (magazine test), surely 10.2s quarters are
possible.....

Sure....lol. i've done a bit of drag racing in my life. R1's have aprox. 132
bhp weigh 385 lbs dry in street trim. Top speed for your Cr is under 100 mph.
high 12's are a big reach.R1's and similiar bikes are running over 125 mph in
the quarter and they have a hard time getting under 10.2's

motocross bikes excel at 0-60. that's the bread and butter. but will get caught
and passed shortly thereafter by most sports bikes like they were tied to a
stump.

here's the facts:

NOTE this is for STOCK bikes, a chassis CR5 would be substantially
better....

R1 : Torque 72.7lbs.ft, weight 451lbs+165lb rider
=8.47lbs/lbs.ft of torque

CR5: Torque 55.7lbs.ft, weight 232lbs+165lb rider
=7.127lbs/lbs.ft of torque

GUESS WHAT? the CR5 with rider carries less weight per lbs.ft of torque IN
STOCK FORM than an R1!!!!
(Torque determines acceleration), so a chassis CR5 should have no trouble
seeing off an R1 at the strip.....

What Mag? What Issue?

>surely 10.2s quarters are possible.....

Yep, but not for the CR5, If it were possible and such a reliable motor,
why don't we see more of these on the track. I started in 1982 and have
NEVER heard of one.

These are actual numbers as reported by Cycle World for a few 99 machines

Honda CBR929RR
Dry weight 413 lb.
0-60 mph 2.75 sec.
1/4-mile 10.35 sec. @ 137 mph
Horsepower 131 bhp @ 10,500 rpm
Torque 69 ft.-lbs. @ 8750 rpm
Top speed 168.0 mph

Kawasaki ZX-9R
Dry weight 434 lb.
0-60 mph 2.76 sec.
1/4-mile 10.39 sec. @ 137 mph
Horsepower 130 bhp @ 11,250 rpm
Torque 70.8 ft.-lbs. @ 9100 rpm
Top speed 169.2 mph

Yahama YZF-R1
Dry weight 415 lb.
0-60 mph 2.87 sec.
1/4-mile 10.36 sec. @ 138.2 mph
Horsepower 133 bhp @ 10,250 rpm
Torque 73.8 ft.-lbs. @ 8250 rpm
Top speed 167 mph

Just my opinion, with a little 2 cents to stir the pot.

didn't say it was reliable!, merely quoted R.R. who used to have a lot of
support/respect here in rmd.

great figures!
interesting that all 3 are so close....
and I thought R1 was king at the strip, my '98 test had it 451lbs,
@10.19s...

Torque does not determine acceleration. Torque and the speed at which it is
applied determines acceleration. This is essentially power (work per unit
time). Here is something to consider. Two cars, "A" and "B". Both are
identical except for the engine and transmission. Car "A" has an engine
that produces 200 ft-lbs of torque at 1500 rpm. Car "B" has also has an
engine that also produces 200 ft-lbs of torque, but at 5000 rpm. Horsepower
is
equal to (torque X rpm)/5252. It terms of horsepower, Car "A" has 57 hp
((200 X 1500)/5252 = 57 hp). Car "B" has 190 hp ((200 X 5000)/5252 = 190
hp). If each car has a transmission designed for its engine, then Car "B"
will accelerate much faster than Car "A". This I can assure you of. This
is why you would not choose a diesel for racing.

Something else to consider. I can produce quite a bit of torque on my
bicycle. This is force applied to the pedals times the perpendicular moment
arm. For a few seconds, I can probably produce an average of 50 ft-lbs.
This is very close to the CR500. If your theory was correct, then I could
out accelerate the 500 since the total weight of bicycle and rider would be
much less than the 500 and rider! Of course this would not happen.

Finally, back in the mid '80's, Dirt Bike mag raced a CR500 against an
Interceptor 500. The CR was re-geared and the tires were changed. It did
beat the Interceptor, but it only ran in the mid 12's (if memory serves me
correctly). The CR (essentially unchanged) would certainly be no match for
a current 600 sport
bike, most of which now break into the 10's.

if you can only produce it for a few seconds, then you must limit the CR5 to
a few seconds and therefore maybe you would win!. I recall horse vs human
races where the human would ALWAYS lead the horse for the first few
seconds.....

OK Ted, lets use your HP figures then......

R1, 451lbs, 130hp +165lb rider
=4.738lbs/hp
Chassis CR5,say 195lbs, 85HP (CR5's are 65HP stock,most tuners can get them
to 85),165lb rider
=4.235lbs/hp

HOLY SH*T BATMAN! the CR5 is STILL ahead even on Teds HP calculations!!!!

Sorry you guys had to get all riled up...

Here are some posts from the DRAGBIKE.COM advice list:

---------

Steven.I had a buddy who bought a kaw kx-500 mid 80s and put 2
perfomance machine wheels/7inche rear slick, pipe,and air shifter and he
ran 7.0s-7teens.He did have some port work too.He weighed about 160-180
pounds and was very consistant.He won more $$$$oa that bike than he
did on his h-2.You will probably run high 80s to low 90s in the mph
department.Good luck!!David

David Greathouse ran a KX500 in S/E and was very successful, ran in the
high 11's 1/4 mile, dont remember the 1/8th mile times. The bikes are a
natural for drag racing if the chassis is set up right, very good power
to weight ratio.

hey guys,
in 1988, i rode a new {at the time) kx500 at palmdale raceway here in
cal, with a stock chassis and just a street tire on the rear. it went a
12.09 @ 119.00 mph!!! in the 1/4, it was a blast! it was for an article
in DIRTBIKE magazine. they took a thousand pics and we ran it until we
blew the motor up.

EXCELLENT STEVE!

based on these figures, a chassis, air-shifted CR5 would realistically be
capable of 10.2s, just like Rich said. QED.

What a buch of Bs. Some clowns write in this Bs. Let's see the points, a time
slip anyone that could verify such hogwash. Are you asking me to believe 123
mph from a relatively stock Kx 500 in the 1/4 mile, and this same person is
used for facts to support this crap.A KX500 couldn't do 123mph falling off a
cliff......much less on a strip.

maybe in Kiwiland that's quick, at willowbank they do 4.83
@466KM/h(290mph) - that looks pretty quick....

Picture me, on my bicycle, lined up next to a CR5 with same weight rider.
We both take off and accerate as hard as possible for 2 or 3 or 4sec...you
pick the number. Who do you think would be ahead after that time elapses?

First of all, I have no doubt that a heavily modified CR5 engine, in a
special chassis, could match the 1/4 mile time of an R1. Hell, use nitrous
or forced induction and its a no-brainer. As a matter of record though,
your numbers are slightly off. The dry weight (no gas) of an R1 is closer
to 415lbs. A stock CR5 puts out closer to 55hp at the rear wheel. 130hp at
the rear wheel is pretty accurate for an R1. It doesn't really matter to me
though. I mentioned the mag comparison of the CR5 vs 500 Interceptor to
make a point. The point is that even the most powerful dirt bike engines
are really wimpy when compared to the most powerful street bike engine. The
Interceptor 500 was far from the most powerful street bike engine of the
day. Good for a 500 of that time, but no match for engines twice, or more,
the size.

I am assuming that these are Pro Stockers? If that is the case, then you folks
should bring these motorcycles forward and run them in some NHRA sanctioned
races. Then you could be a record holder. NHRA www.nhra.com Pro Stock record
is 7.1 sec in the qtr. Bring it forward and have your name posted in the NHRA
record books. That 4.83 @ 290 could replace "PSB 7.154 191.48 Oct-99 Matt
Hines - Trinidad, CO '95 Suzuki GSX-R Houston, Texas".

Yeah me too!, the best part is we are all pretty civil about it, flinging

really? most tuners can get 85 hp they must be using splitfire plugs and

go? That 236lbs or so you mentioned for weight. That was dry weight wasn't
it? If so how come you are using wet weight for the R1? BTW that is a pretty

Interesting that your top fuel (car) is MUCH faster than us (4.48/326mph to
4.83/290mph), but our TopBike is quicker than yours (6.72/190mph to
7.154/191mph), must be the cost factor, or I guess you have a longer history
in performance car engines.....(bike drags being a little more recent?)

Your claim that the Cr 500 made 65 hp stock seemed high so I went back through
some old issues(and my wife complains about me keeping them!) I found a dirt
rider mag/ Dec 1985 on page 84 there were the specs on a 1986 Cr500 guess what?
It weighs 235.5 lbs dry and 250 with a full tank. It made 47.5 hp at the rear
wheel at 6000 rpms. Torque ratings 41.5 ft lbs at 6000 rpms. where did you come
up with the 65 hp from a stock Cr500? probably the same place you found your
other facts......Hmmmmm. I welcome your rebuttal....<vbg>Why don't you
recalculate using real numbers this time then get back to us?

64.6 Ps/6000 must be at the crankshaft, notice 47.5 kW/6 has to be rear wheel.
Thanks for posting the links info it's a far cry difference then your original
claims.The R1makes 150 hp at the crank BTW.That being said....with the obvious
power to weight advantage of a bike like the R1 a 10.2 quater mile time out of
a highly modified Cr 500 is virtually impossible . I don't think it would be
impossible to get one in the 12's if it was highly modified....I stand by my
original statement 9 secs in the 1/8 mile high 13's low 14's in the quarter for
most Crs.

Nope. Wrong yet again!! 47.5Kw = 64hp, they are just different units of

kW means kilowatts. It's a metric unit of measure. 1.34 hp = 1
kilowatt. Being an Aussie, he pulled his information off of a metric
website. I'm not familiar with the Dirt Rider article, but dyno
readouts are often in kilowatts.

A kW is a kilowatt or 1,000 Watts. The Watt is a unit of measure for power
in the metric system. It is equal to 1 Joule per second. One Joule is
equal to a force of 1 Newton applied over a distance of 1 meter. 1hp is
equal to .746kW.

BTW...I found that old DirtBike mag with the CR5 vs 500 Interceptor race.
The CR was stock with the exception of a street rear tire, different
gearing, and holes drilled in the air box. The best run was 12.33 @ 102.35
(corrected). The riders claimed that it could do better with even taller
gearing (It topped out well before the lights).

And in HP too. The kw vs HP is digressing from the discussion. Internal
combustion engines for human propellant usage are rated in HP.
Electric motors are rated in either HP or kw.

Yes! - you are quoting a magazine using a Dyno in 1986, anyone who knows
anything about Dynos will tell you that you CANNOT get absolute figures from
them, you can only use them for apples to apples comparisons.

I suggest that Honda Motor Corporation in the year 2000 would have a much
better chance at providing the correct figure than the DirtBike boys after a
days drag racing and few Bud's back in 1986!

> any Bs has rubbed off on me it came from your direction.......The only Bs
i've
> seen are your outrageous claims of Cr500's running 10.2's in the quarter

I did not claim it, I quoted it from Rich Rohrich!

By now you may have guessed that yes, I was an ex bike drag racer, running a
GSX-1100 (stripped,cammed,balanced,flowed,slicked,welded up clutch but no
air shifter) which ran easy 10.8's

I now own a CR500, and although I didn't get the chance to run them back to
back, I can tell that the (stock) CR500 feels stronger than the 1100 (which
was about 110-120HP)

I can also tell you that I have ABSOLUTE FAITH in Rich Rohrich's quote, that
a chassis, ported CR500 running gas (NO2) could run10.2s. I would probably
even bet my house that it was possible.

You do not believe this, and do not appear to know who RR is.

I wonder if you also , think honestly now, would be prepared to say that
such a bike ABSOLUTELY COULD NEVER UNDER ANY CIRCUMSTANCES TRIP 10.2s?
If you can answer 'yes' to that, and still consider you don't talk BS, you
are certainly one deluded fellow.

Finally, since neither of us can either prove or disprove the claim, I guess
we will have to agree to disagree and leave it at that.

Thanks again for you input, and I look forward to our next discussion! :)

see ya dude,

Depends on where you are from. I remeber seeing ratings in HP, kW, and PS
(Pferde Starke). Guess where that was.

Matt I was struggling to explain hp to Kw to him, there was no way I was
going to confuse it further with Pferde Starke to Kw to hp!

So yes I used 47.5Kw= 64hp (actually 63.7 but I rounded it)

NO.. you check again.. :)
He never mentioned hp anywhere!! his were in Pferde Starke
I quote him saying 64.6PS=47.5kw which it does.
I must admit I did make a typo (typed PS instead of hp :)) but it was too
late after sending the post.

But I mean how can you argue his post when you're going and changing the
units in which hes quoting figures??

The bottom line is basically a CR5 on the strip is not going to break the
11sec mark :)

NO... YOU CHECK AGAIN
the 64.6PS came from the Honda site

Your only correct statement

Remember this? 'So yes I used 47.5Kw= 64hp (actually 63.7 but I rounded it)'
Another correct statement

I'll summarise 64.6PS=47.5kw = (approx) 64hp
WHAT DO YOU NOT UNDERSTAND?

>But I mean how can you argue his post when you're going and changing the

To make it easier for him. You may not know it, but many engineers use PS
and HP virtually interchangeably, since they are so close anyway.
IN THIS ARGUMENT IT MADE NO DIFFERENCE

You don't do a conversion in which the given data is 1dp an then 'round' the
answer to 0dp!
Thats like pre 1st year learning!

Many engineers??? Don't speak for me at all!
'I' AM an engineer... I'm working with 5500hp engines EVERYDAY.. and there
has NEVER been a single time that I have run across anyone whether its in
engineering, motorsport anything that uses PS as being HP.
They're not the same therefore they're not mixed.. EVER
Its like saying a US gallon is the same as a UK gallon.
Gallons a gallon?? I think not!

Anyway..
You keep thinking that a CR5 is going sub 11sec and maybe Santa will bring

OK,lets make it real simple for the engineer....

Matt Porritt,Rubber Chicken Man, Reckons 11+

mmmmm, I might put my money on RR methinks.

go and bolt on another exhaust RCR man.

From my understanding, while the vocabulary words are the same, that is Pferd
is German for Horse and so on, the actual methods of measurment and arriving at
that number are different, so that Hp and Ps aren't quite the same.

Like if you took a Z28 Camaro measured by the Germans in Ps you'd get a
different number than the US dealers advertise for Hp. (And they're both
probably lying)

http://www.chevroleteurope.com/germany/camaro/german/cam_xxx_de_de_z28.htm

212 kW/288 PS bei 5.200 U/min.

while in Canada:

http://www.gmcanada.com/english/vehicles/chevrolet/camaro/cama_details.html

Horsepower - 305 @ 5200 rpm, Torque
335 lb.-ft @ 4000 rpm

So whatever, there also could be variations between export models...

Don't stop now, it was just getting good. It almost broke down to the

No apology needed. It was a good discussion (for awhile anyway), and,
if I ever hit the lottery, I'll be sure to purchase a R1 and build a
chassis 500 and shake 'em down. All findings will be reported to RMD
post haste.

Though the working population are starting to get tired of being stood
