Jeez,,you guys kill me,,lol

 

Let us have our fun!

 

not through the twistys it wont!! but the vrod does better rollin burnouts..true

 

I got two buddies, one with a road king, the other with a fatboy.
I don't now about the long race , but off the line my 1200 sporty can smoke them.

 

That's what I have, a 1200 sporty custom. It feels very fast to me!

 

Stock v-rod is the only one that can run beside me but of course my my 04 custom isnt stock though either

 

 

Have you ever ridden a v-rod? My friend has a 06 street rod v-rod stock will out perform any stock sporty made in the twistys

 

It's not how fast you can go... It's how quick you get around!

 

Before the 96ci Big Twins the 1200 Sportster was second only to the VROD in performance stock for stock. With the introduction of the 96ci engine, the lighter Big Twins like the Street Bob are pretty close and it would really come down to rider (as most races often do).

Now, when it comes to modified bikes that's another story...

Weight of a new Sportster 1200 wet is about 580. (Solid mounts were at the 500 even mark.) I've seen Sportsters modified to produce about 100hp at the wheel giving them a 5.81 hp/lb ratio.

A big twin like the Street Bob weighs in at 667 wet. It would need to produce about 115 hp to match that ratio. A heavier bike like the Fat Boy Lo (731 lbs wet) would need to produce 126 hp to match it. Heaver still like a Road King Classic (810 lbs wet) would need almost 140 hp to match that kind of acceleration.

I don't know what HP numbers are stock for these engines but stock the 1200 has 7.34 lbs per ft/lb of torque and the Road King Classic comes in around 8.80 while the Street Bob is about 7.25. Like I said, the 96 ci engine in a lighter Big Twin is a quick Harley.
