Vrod vs Sportster

[ScooterTrash]

This is a letter written by a guy on the XL list(sporty) who said he outran a VROD and everybody called BS on him, so this is his response letter:
I thought it was interesting, he went through all this mathmatical crap to back up his claim:happy3:

Hey Guys,
I just found some data that supports my contention
(and personal ovservations) that a Sporty can beat out
a VRod. You may remember that I made this claim a few
posts back and several of you jumped on me saying that
this could not be. I say balderdash...It can happen.

The VRod data that I'll be quoting comes from the
Jan/Feb issue of Hog Tales page 35. The Sporty data
comes from my Dyno runs on my own modified Sporty.
The VRod is a stock 2006 VSRC(1130cc). My Sporty is a
2004 XL1200R with SE Air Filter and Supertrapp 2 into
1 pipes, Dyno'd for F/A Ratio of 13:1 and Exhaust
system tuned for max torque at 3250 rpm.

The VRod's weight is given as 600 lbs and the Sporty's
weight is 558 lbs. At 3500rpm, the Sporty's
Torque/Weight Ratio is 0.129:1 and the VRod's is
0.105:1. Note that the Sporty's is about 23% more torque/weight at that rpm. The Sporty also develops more HP at 3500rpm than does the VRod (42 for the VRod vs. 48 for the Sporty for an HP/Weight advantage of 23%). Given that the VRod is a heavier bike, the HP/Weight ratio also favors the Sporty. All this converts to a faster Sporty (at the start, anyway).

At 6000rpm, the Sporty has achieved Max HP of 74 while
the VRod is still climbing at about 74 also.
Given the lighter weight and greater torque, the
Sporty should achieve max HP sooner than the VRod.
At max HP, the VRod beats the Sporty with about 110HP
compared to 74 but by then, the race is over.

Because of the greater amount of torque, particularly
at the low end and the greater amount of HP (also at
the low end) and the lighter weight of the Sporty, the
tuned Sportster should beat the stock VRod.

On the road, my Sporty DID IN FACT leave the VRod in
the dust. I don't know for sure, but I think the
Sporty would beat the VRod in the 1/4 mi.

Finally the VRod lists for $16,295 while the Sporty
lists for $8,595.

Gimmy a Sporty anyday, anytime, anyway.

this is a response from a vrod owner:

before you make a money bet on it, the Vrods flywheels are a lot less heavy than those in the sportster engine. that will make the Vrod rev faster (just like the buell X1, S1, M2, ...will outrun a tuned sportster that makes just as much power and torque as those buell's) and also, if you dragrace a Vrod with your sportster, the Vrod rider only needs to let the clutch slip at around 7000rpm for a pull that will make you feel like standing still. maybe if you would cut off some weight of those sportster flywheels (it will cost you a little torque in the low rpm range) it would rev fast enough to keep up with a Vrod, just don't bet on it.

and yet another reply that makes sense:

You can not compare engine torque values on different bikes with different final drive ratios. Torque is very much misunderstood by many. If you calculate the torque values through the primary drive, transmission, final drive and rear tire dia.to where the rubber meets the rode. Then you can compare those torque values, the bike that makes the most torque where the rear tire meets the rode if the both bikes are the same weight will accelerate faster. The easier way to compare is look at horse power curves of each engine in their operating rpm range. A Vrod or 600cc sport bike when ridden hard by a decent rider will probably not see less than 5000 rpm. The Vrod has approx 40% lower final drive than the Sportster both in 5th gear. When both bike are running 3500 rpm in 5th gear the Vrod is still making more torque where the rubber meets the road. The Vrod is also running slower than the Sportster so if he speeds up the same ground speed as the Sportster the Vrod will be turning 4600 to 5000 rpm. Now compare the engine horse power of the Sportster at 3500 rpm and the Vrod at 4700 rpm then factor bike weight in and see how they compare now also look what happens to horse power up to both bikes engine red line from these points.

hmm i will still take that v-rod over the sporty any time any day.....With a good rider in a RACE all that stuff wont make to shits of a difference.....You know that just as well as anybody elce....

but hey its whatever...I did find the fact that the one guy said a v-rod or a 600cc sport bike when riden hard will be above 5grand....HAHAHA a 600cc sport bike will be above 12grand when ridden hard.....

But anywyas cool topic v-rod wins.

[Ramius]

^^^^^^^^^^^

Listen to it SCREEEAAAAAM I remember even with earplugs my 600 would feel like it was rattling my brains out above 11 grand =)

[B.S. Motorsports]

See my bike isnt to bad up there at about 10-13 its buzzy but not as bad as my buddys r6 thats for sure...

[hotcknstrips]

my kawi will smoke them both. :keke:

Either that V-Rod owner had his bike for only a day and knew nothing of it or he's just a plain, crappy rider.

damn vrods, always picking on the sporties

No way mang! I like Sporty's!

[B.S. Motorsports]

but v-rods are better lol

[speedismo]

Vrods rule. Sporty's should have been discontinued many years back, like rest of harleys. :laughing6
oh wait, I like the fatboy too, for the poser factor!

oh snapz, right. how do i escape the wrath of big bad harley boys now:confused1

*follows Jake and runs away*

[train460]

Vrods rule.!
second place means you lost.

Ooooooohh. Ya'll are gonna get it if/when Scootertrash returns from the Land of the Banned(TM). :keke:

[R6MILF]

I have to say sporty's...there classic and I'm biased cause I rode my dad's 86' 1200 sporty in High school.
But when I wanted my own bike again i went for the R6 cause I can't afford the maintenence of any harley, and the oil kept staining my boots!!!

[arturo3rd]

second place means you lost.
good post

Is Scooty banned? wat for, for uttering the 'N' word?:confused1

Yeah, he wasn't playing nicely with the other children. :angry7:

[B.S. Motorsports]

when did this happen and does anybody have a link!

[arturo3rd]

yes. something about enough n's to be in a tarzan movie.

I like sporties more, stick to the original designs and leave the new school shit to jap bikes. dont get me wrong i like the vrod but i dont think i would ever own one. I like the basics where nothing flows and wires and oil is everywhere. HD is making millions with a design that hasnt changed much in the past 100 years, why change it now?

Agree but i think harley makes more $ from other stuff than they do on their bikes. T-shirts, doo-rags, etc.

[train460]

a harley buddy came by the house last week on his new-to-him bandit as his harley is in the shop. He had on a harley t-shirt. I told him that the micro chip imbedded in the shirt that will let a harley start is not needed on his bandit.

hehehhehee, I saw it,
real world, the harley world should follow the direction of the water cooled, Revolution power plant in the vrod.
The sporty and others have antiquated pushrod style, air cooled motors, althogh very cool sounding and I love em, they are old, old ,old technology.
Mine hauls butt now, but I've dropped some coin into it to get there. whereas the revolution motor makes the power I have all day in stock trim.
I still love my sproty though, its just dang cool and lots of fun to ride.
Maybe I'll by a vrod next, maybe not and get the bagger I've been wanting.

mine hasnt cost me any maintanance I didnt initiate and mine leaks zero oil

[TxVrod]

My next Harley is gonna be a Road King bagger

[Greenway Smokey]

maintence is pretty cheap. Especially if you do the routine maintence and don't wait for something to break.

I think you need to watch these bikes in the begining. They have a lot of schedual maintence at the begining and that feels like it costs a lot because if you ride a bunch then you will at the dealer a lot.

Mostly in puddles underneath the bike. :keke:

Hell yeah, i want a bagger!
