Does anyone happen to know the horsepower numbers for the new 2004 Sportsters? Both 883 and 1200? Thanks! | ||
| Josh_ |
motorcycle.com claims "The 883 engine generates 53 peak hp at 6000 rpm and 51 ft. lbs. of torque (crank) at 4300 rpm." "The 1200 on the other hand, ... is 70 peak hp at 6000 rpm and 79 ft. lbs. of torque (crank) at 3500 rpm." | ||

What the hell are you doing buying a Sportster? Trying to cruse cool when Susan's on the LowRider?  | ||

Spinning slightly off the subject... and since Aaron just posted... how much hassle would it be to fit an 883 into a XB9S? (Now many are thinking why would someone want to do something stupid like that? Well, I would like to find a salvage XB and dumb it up for my son to use in college for cheap transpo. Something cool looking but with beginner horsepower. My first idea was a blast engine in a salvaged XB.) yeah... yeah... stupid idea... humor me please! | ||

Put an XB front head on a Blast engine and slip it into a 9S frame. Just a thought. Or just buy him a CM450 Honda for $500 and save yourself a lot of hassle and concern. YMMV | ||
| Dasxb9s |
The thought was later put the XB9 engine in with a race kit when he grows into the hp. Then have a sportster engine to hop up. ...and the XB looks cooler than the Blast. Though I have a Blast that could provide a "donor" engine. Just thinking out loud. | ||

No problem, without thinking up stuff we'd all still be rolling around on rocks. | ||

Josh ... I LIKE Sportsters ... this ain't my first. I really like what they did with the 04's. Big improvement IMO. | ||
| Fullpower |
except for the part where they added 80 pounds. | ||
| Josh_ |
Well my first two bikes (ever) were 92 (last year for the chain drive) and 96 (last year for the peanut tank) 883 Huggers. Can't believe HD stopped making that model. 'Course I can't believe Buell stopped making S3s either. According to HDs website they went up 66lbs. The Sports now tip the scales at 555 dry. My incoming FJR1300 is a claimed 537 dry (with saddlebags) and a measured 631 on the road (anyone weigh a '04 Sporty? motorcycle.com did a comparo and included it - but didn't weigh it) | ||

Now that they have rubber mounted the engine I find myself thinking about a new Sporty all the time. They are nice simple motorcycles that can be used for a multitude of purposes except maybe track days. Well maybe track days if you want to have alot of people shaking their heads. | ||
| Fullpower |
manufacturers "dry weights" are an absurd fiction, quoting them in public should be a personal embarassment. once you have removed such "accesories" as tires, battery,coolant,brakefluid,transmission and engine oil, and all suspension damping oil you no longer have a functional vehicle, so the weight of such a heap of parts is irrelevant. | ||
| Josh_ |
Which is why it's nice that motorcycle.com normally weighs the bikes and dyno's them so you can compare dry and crank vs real and rear. Even worse is its not even the ship weight since they come with batteries and susp. fluid. Kenb - they're great track bikes, especially if the track is dirt. | ||

Aaron, I'll second the kudos on the new Sportys. My neighbor accross the street has the new Custom version. I've ridden it a number of times. NOTHING like the old ones. Kind of fun actually. | ||

The dyno I've seen on a stock 1200R had 61hp & 71 ft lbs. The dyno Aaron posted on the stock 883 was probably on the low side. I haven't seen any dyno's that low on 03 & earlier 883's. Most were low to mid 40's and the 04's should put out more. I just bought an 04 1200R. Wonderful bike. I think it corners very well and plenty of power stock for my intended purpose. | ||
| Aaron |
I don't see anything new on the 883 that would add any power over the previous models. Unlike the 1200's, they did not get a better set of heads. Same "D" cams as before, too, although I understand the 1200's got "W" cams for 04. Yeah, the 39.5 seemed low to me, too, but that's all she had. Need to get me one of them happy dynos I guess. I'm still thinkin the SAE isn't good to us up here. The chart above is pretty telling ... notice how the power peak moved down the rpm scale with the increase in displacement. It's running out of breath. Teeny tiny little valves in them 883 heads. edited by aaron on June 22, 2004 | ||

good canidate to see just what kind of change XB heads would make? | ||
| Henrik |
Dave; you've been around here long enough to know that you can trust Aaron's dyno #s . If there was anymore in that motor, Aaron would have found it. That said, I had no idea that the Sportster motor had that little power. Henrik | ||
| Scrap |
Henrik, I dyno'ed my `1200 R with SE ignition,SE air cleaner and straight pipes and got 77hp at the rear wheel. | ||
| Josh_ |
Hard to believe they bumped the 1200 up so much... well ok it's hard to believe it took this long to follow Buell's lead | ||
| Henrik |
Richard, that's not bad at all  I guess I didn't think much about it, but even if Aaron's dyno number is at the low end of the scale, around 40 HP really isn't that much for a bike of that heft. Just curious. Henrik | ||

Guess, HD just didn't want the Sporty's to be outgunnin' the big twins... After a Buell, Sporty's seem kind of anemic. Lot's of folks just don't care about HP or torque, just want to see themselves in the chrome pieces! | ||
| Josh_ |
...just want to see themselves in the chrome pieces! Speaking of which what do you suppose your '68 XL would dyno? | ||

Walk into a HD dealership and seriously compare the 2004 DynaGlide and the 2004 Sportster 1200C. Engine torque: 85 @ 3000 vs 79 @ 3500 Weight: 622 vs 554 Wheelbase: 62.5 vs 60.4 Price: 11,995 vs 9,425 For 95% of the shoppers that is a $2,500 coin flip. Throw in the 883 and you have effectively killed the Dyna in sales. 80% of the Sportster shoppers will not notice or care about the power level of an 883 vs a 1200C, they're price/image shoppers. The 883 is the Blast of the Harley line, the entry bike, at least according to a few folks I've spoken with. The 883 can be pepped up with a ready-to-sell packaged kit, available at more dealerships than a shifter arm for a Buell is. The End of Year numbers are going to be real interesting for 2004 once the year is over. As are the next few weeks and months. YMMV IMHO yada yada yaw | ||

Just wondering off the top of my head, go with me here a bit. If you put a set of XB heads, on the 883, adapted the XB manifold for side draft rather then downdraft, think you could get away with the DDFI from an XB9? If so, what kind of difference would it make? I mean this is theoreticle and all, my brain is fried and stuff but I just started pondering it... | ||
| Ingemar |
And how are you gonna control the ddfi? From which sensors is the ecm gonna get it's input to determine the A/F value? You would need something programmable and go with closed loop configuration. Carbs are easier AND cheaper for the DIY guys IMO. I don't see an advantage at all, especially not for someone who knows how to jet his carb correctly. But the xb heads are definitely the better choice for sportsters. Even better than the TS heads. | ||
| Wyckedflesh |
When you use the XB heads, there is the CHT sensor, the pickup for the ignition is already there since its an electronic ignition. The IAT could probably be tapped into the backside of the sporty's airbox. This wasn't a question of money it was a question of what if. Even the O2 sensor could be added easily enough if there wasn't one there already. | ||
| Ingemar |
You probably end up with a machine running just as smooth as an xb  | ||
| Wyckedflesh |
In looking at it, I would think you would end up with a detuned 9 in a cruiser chassis...better performance then the stock 883 but have it fall just shy of the 9's performance due to the displacement difference. | ||
| Ingemar |
the 883's have a longer stroke than the xb9. The gearing, cams and pistons are different too so your looking at two different engines. Performance wouldn't be comparible IMO. edited by Ingemar on June 25, 2004 | ||
| Wyckedflesh |
Sorry Ingemar, I missed the stroke difference when I went through the sheet. I was looking at the bore difference and not the stroke. |
