HP for 2006 XL1200c

[Gone]

Anybody know how many HP the 2006 1200c has. The only thing on specs i could find were 79 ft/lbs @ 3500rpm. Some guy told me it would be 52.6 HP which seems low.

[cgp-1200R]

I read in an article that the stock 1200 has 70 HP @ 6000 RPM, The 883 has 53

intesting my z1 had 83 HP @ 6000 RPM but 57 ft/lbs @ 3500 RPM

Check out [motorcycle consumer news] Best article ever written on Sportsters. I'm sorry I don't know how to do a link. The 1200 has 70HP, 58hp at the rear wheels. The article tells you every thing about what improvements are on the new sports.

Depends on whther you're talking rear wheel or crank.

Not being a mechanic, I'll have to ask. What is the diff. I just need to know what the max HP is of the motor. The reason i'am asking is because i am importing the bike from california to europe and the customs here ask what the Hp is for import tax purposes.

There is a frictional loss in the drivetrain of ALL vehicles.

So, manufacturers GENERALLY publish (for bragging rights) the CRANKSHAFT hp and torque figures.

If you dyno ANY vehicle you'll find the rear wheel HP/Torque (or front wheel hp/torque as the case may be on many cars) is less, sometimes significantly less.

Harley doesn't usually publish crankshaft HP figures. THEY DID when the rubbermounts first came out and IF I remember correctly, what you're quoting is there or real close.

HOWEVER, if you're talking about less hp = less taxes, I would get my hands on some dyno sheets cause they're gonna show LESS.

The Rear Wheel HP of a STOCK 1200 is probably in the 60s

The Rear wheel HP of a STOCK 883 is probably in the 40s

Harley publishes some dyno charts in their Screaming Eagle brochures that show stock 1200 hp and torque curves. Providing that to your government regulating body might be enough to get you the cheaper rate.

Thanks Kev

I'll check out the screaming eagle brochure

If you are looking for a legal documentation for customs then what you want is an MSO (manufacturers stated origin). I get one with every bike or car I purchase. It has the manufacturers stated SAE hp on the document as well as weight, body style, VIN and all sorts of goodies. They are free and simply need to be ordered at the time of purchase.

my 2006 1200R dyno'ed 50hp before stage 1 (20 miles on the bike) and 73hp after stage 1. after 5,000 miles it dyno'ed 70hp, the mechanic said it was because the room temp was cooler on the original run.

Could be mixing apples and oranges here, and I'm paraphrasing because I don't have the book in front of me at the moment. Buzz Buzzelli, in his Sportster Performance Handbook, points out that HD's published HP figures are inflated by something in the neighborhood of 10 percent as I recall. So a 1200C with the AC/pipes/jet combo puts you up around the published HP figure of 70. Don't recall if these were crank/rear wheel numbers.

Someone please help!!
I changed my derby cover on my new 06 1200 sportster custom and of course
the transmission fluid ran out,approx.a quart.
where do I refill the tranny oil and how much should I put in?
Also I unknowingly poured the lost tranny oil into the engine fill.
About a half quart.I was thinking that the engine oil fed the tranny too.
did I destroy my new bike?Iwas told that the engine oil is different from
the tranny oil.My 1000 mile service is due in 250 miles,can I wait til then
to change the engine oil?Please help out a lost new harley brother.

On the left side just above the shifter is a window with 2 allen head screws. You must pull the plate to fill the primary. The whole thing only holds a quart so if it were me I would drain it first by pulling the plug that is just behind the tensioner bolt on the underside of the primary cover. You don't know exactly how much you lost from the system so start from scratch. As to the 16 ounces you put in the engine, I wouldn't worry about it if it isn't overfilled and you only have 250 miles to the scheduled service...

Sorry for the off topic reply folks but I thought this was worth taking care of.........

The formula for computing HP is horsepower = rpm x torque / 5252. Now that is of course a theoretical computation, but I think it is pretty close for a 1200 when you plug in the numbers you listed. It comes out to 52 HP.

Have talked to the Harley main office to get all the papers on my bike. Maybe it will show up there. If it does, i'll post it. Have asked the to specify HP on the doc.

[LuxBlue]

About 70 hp stock....add SE II exhaust or other free breathing pipes, a carb rejet and Hurricane air filter to get another 4-5 hp.

[procad00]

using the numbers you gave of 79 ft/lbs @ 3500rpm the horsepower is 52.64 subtract 10% for driveline and we're down to only 47.376 (79x3500/5252x.90)

Procad00, max HP is not at the same RPM as max tourque.

[bosskag]

harley $tealership told me the 1200 sporty has 70 hp (engine) (same as the 1450, but don't tell your big twin brothers) :-)

[adam]

I dynoed my 05 1200c today and got 71hp at the rear wheel. I have an air cleaner kit, Vance and hines big shots, and rejetted the carb. The guy said that a bone stock one would probably be in the 50's.
My friend did his 88" fat boy and got 71 or 72 with the same mods.
My peak hp was at around 4500rpms. This is all factual and not what some one wrote in an article

Procad00, max HP is not at the same RPM as max tourque.

No but the two are equal at 5,200 rpm.......

[aka_Matt]

your peak HP was at 4500 adam?? that sounds way too low... my peak TQ was at 5000, with HP at 6000...
