i run my buddies all the time on sport bikes... with a bunch of motor work i do just fine

 

Ducati's latest v-twin on its Multistrada is a 1200 cc Engine. Same displacement as Sportster and same 2 cylinders and it makes 155 bhp. Its all about the technology.

 

A P-51 Mustang, incredible in its day, is no match for a modern jet fighter. A V-Twin, which is my favorite engine design due to the kind of power it puts out, takes many mods in order to win stop light races, if at all.

Fuel management, fuel injection, electronic ignition, twin cams, et al, a V-Twin is still basically just a slice of a radial engine. Biplanes, anyone?

 

Andrew Hines is also on a larger displacement bike than the metric bikes. His is roughly 2600cc while the inline 4's are only 1600cc. Also, when talking about Stock motorcycles, the metric bikes have the obvious advantage because they are running essentially race spec equipment stock but the Harleys are more built for cruising. Set-up a sporty with more race spec stuff similar to a metric inline 4 and you will get close to the performance but never equal. Somewhere after all the bowed up chests and big egos the laws of physics come into play and the winner will be the inline 4 design vs V-twin.

I bought my Sportster knowing what it was and what it is capable of and I am in no way going to race a sportbike, I have had plenty of them and know their capabilities.

 

Liquid cooling allows tighter tolerances, which allow higher stress operations.
Multiple valves per cylinder mean more efficient fill.
Lighter weight means higher power to weight ratio.

All of this conspires against you. Your Harley doesn't have a chance against 'em.

 

All else fails, get a VRod

 

You Guyz are Killin me,,,

Go race a Big cruiser,,a 1300 cc yamaha or such,,that will
Get yer pride restored real fast.
