I just got an '03 1200S, stage 1. It has bassani street pro. pipes, and Kury Hyper V air box. what kind of time and and top speed can I expect in the 1/4? Man, I'am lov'n this bike.:banana

One of our members has one that does 11 seconds in the quarter, I think its more than stage one
Ask Stevo, he knows Sportster's real good
:tour

Best WAG would be for a 1/8 but if your good and can get to WOT and feather the clutch quickly without the wheel pointing to the moon,

maybe low 1.90's in the 60ft
Low 8 seconds ET's
MPH around 82-85

You'll be suprise what a good rider could do

I saw a figure of 12.96 for an 04 1200 I dont know if its right or wrong but I would say its in the general area .

The rubbermount Sporty's are faster than the older solid mounts. A 12.96 sounds a bit fast for a solid mount; even a 1200S, but I could be wrong! :dunno

I would put my money on your bike running low 13's. I don't know what your skill is in racing, but low 13's are difficult to achieve in a Stage 1 solid mount Sporty without knowing what your doing! haha

I HAVE BEEN TRYING TO SHOW MY TIMING SLIPS BUT CANT GET THEM TO LOAD AS A PICTURE ( I AM BASICLY HOPELESS ON THE COMPUTER ) BUT IT SHOWS MY 98 1200S BLASTING THE QUARTER MILE IN 12.89 @ 100.3 MPH COMPARED TO MY FRIENDS 05 1200R (BOTH STAGE 1) 13.44 @97.2 AND I WEIGH ABOUT 40lbs MORE. I GUESS MINE IS NICE AND LOOSE WITH 50000 MILES ON IT.

with a hyper charger, 1 3/4 in dragpipes with torque cones, thunder slide, se race ignition moduel, taylor plug wires and accell plugs, i ran a 13 sec flat in the 1/4 cant remember the speed but that was onkly the second time i had ever put it down the track and i guarentee i can put it in the high 12.80's now. with the same equip as above

ok so what is a 1200 S i have been looking at the harley site and cant seem to fine a 1200 S ??? 13.0 dont sound bad !

Sportster 1200 Sport
They were only made for a few years. I have one and love it. At the time they were the more performace, less chrome sportster.

The rubbermount Sporty's are faster than the older solid mounts.

Are you sure? What's the reasoning on this statement? I would think that a solid-mount 1200, weighing 50 lbs less than its rubber-mounted counterpart, would be faster just from the standpoint it has less mass to carry. Oh well, what do I know? I'm sure there's a good explanation for it.

Cheers,

Depends on the rider, like launching at full throttle slipping the clutch as fast as you can and also doing full throttle shifting can drop a few tenths off that slip.

I agree. 580+ lbs. for the rubber mounts. Without rider they barely hit the old muscle car standard of 10 lbs. per hp. A 13 flat would be exceptional for a stock rubber mount.

This has been covered before, the power gains for the 04+ 1200's offset the weight gain, and they end up being about equal.

Way to many variables to give any definitive answer. The newer bikes have the better breathing heads. Thats why a second spark plug was needed on the "S". Anyone, do the "S" and the 1200 R share the same cams?
The "S" has much better suspension wich puts it in a different realm as far as I'm concerned. Throw in a few turns and the "S" model becomes a real Sport Bike.

Iv'e seen many dyno results with basic stage 1 on the rubbermounts pushing right around 75 HP. How about the "S" model?

I can turn 12.9's consistantly on a '96 883 conversion. Stock883 heads, nothing special.http://videos.streetfire.net/video/f83b9551-e950-42e8-a61a-98080134e101.htmhttp://i101.photobucket.com/albums/m54/cwissler/dragracewheelie.jpg

Motorcycle Consumer News, which seems to be about the best source as far as mags go, has the times as follows:

1200S, tested 10/99

1/4 mile: 13.15@98.65

wet weight 526

RWHP: 56.4

TQ:65.5


1200C, tested 12/03

1/4 mile: 12.99@100.11

wet weight 585(larger tank)

RWHP:58.0

TQ:68.7

From what I"ve been able to figure thru various mags, the extra weight from the rubbermounts seems to be more than offset by a little extra power and a more useable powerband and torque curve.

I love the S models, but I cringe at the thought of winding a non rubbermount past 5 grand, much less 6 like the new ones.

Nice info there but the results are really meaningless unless the weather was exactly the same and the test was done on the same dyno and at the same track with the exact same conditions.

We could give you a number but that number is meaningless because of differing track condition, rider skill ect.
Go to the dragstrip and ride your bike and you'll know for sure and don't be disappointed if you not in the 12's.

Those results look a lil off as far as I'm concerned, but maybe not. Most reviews I've read though list the '03 1200S running a 12.9 from the factory.
Also I have an '03 and after putting 5000 miles on my bro's '01 883 and my 1200S they are completely different bikes vibration-wise. My bike's vibes really smooth out after 3400 rpm and I have an SE 6800 RPM ignition that I take advantage of every so-often. I rode with a guy on an '07 R1 yesterday, he was nice enough not to completely lose me all the time. He was impressed with bike's performance compared to other HDs, though. I hang in the corners right there with him. FTR I got mine up to 125 mph yesterday, only performance mods are SE ignition, plugs and wires, and I cut out some of the stock backing plate. Also FTR I had a slight backwind and my cafe bars really take me out of the wind. I can't wait to see this bike in action after full stage 1...

If you don't have a Screamin' Eagle ignition get it. I bought mine NIB for $60. Best money I ever spent on it.

Actually, of the few tests I've seen of the 1200S, that was the quickest I've seen by at least two tenths. The other test I've seen of a rubbermount had it at 13.04, also right at 100.

I also know all about weather conditions affecting ET, from my own runs with different cars over the years...it's just a guideline, but from what I've been able to decipher through different tests, it still looks like the rubbermount is a little quicker. I would love to do a few runs against one to see though!

Oh yeah, as far as vibration goes, I have read that the S models seem to be smoother, maybe due to the twin plug design? I haven't ridden one, so I really shouldn't comment. The only solid mount I rode was a 96 1200, and it shook so hard after 4500 I thought maybe something was wrong, but there wasn't. I would love to ride an S sometime though...I am putting the S shocks on mine in the next week too.

The 1200S runs TEN TIMES smoother IMO. okay maybe a little exaggerated but not much. My bike rides like a completely different bike compared to my bro's '01 883. I run 5000+ rpm many times on the highway with no real issues.
