Acceleration vs 2005 road king classic

A friend of mine is purchasing a '05 road king classic, and I was wondering how my vn750 would compare to it in terms of acceleration. I know my engine is half the size, but it feels pretty darn lively to me. Anyone have any experience with the Road King? Personally, if I was going to spend near that anount I would get a Nomad, I love the way that bike looks.

In my opinion I believe the HD will out do the VN.

VN 750 hp- 66 @ 7500 rpm Road King- 67 @ 5200
VN 750 Torque- 47.7 @ 6000 Road King- 80.4 @ 3400
VN 750 weight 530 # approx Road King 790 # approx.

Can the power to weight ratio advantage of the VN750 overcome the huge low end torque advantage of the Road King ??

Probably not, but I'm still impressed by the performance of the VN750

this is what I could find

VN750; 1/4 mile seconds @ MPH 13.70 @ 97.6

FLHRS Road King Custom; 1/4 mile seconds @ MPH 13.44 @ 96.44

so give or take.....it gets a run for its $!

if it goes vroom or boom, I LIKE IT!

My experience was with an 02 RK that I got to ride for 50 or so miles on a road trip when I still had the 750. We swapped bikes for a spell. Of course, going from the nimble 750 to the RK was going to make the RK feel pretty clumsy and it handled pretty poorly IMO. I had ridden another friend's Vulcan 1500 classic earlier that day as well so I had a pretty close comparison to that bike also. The RK really lacked in every area to me, even when compared to the 1500. Everything was smoother and softer to the touch (clutch, shifting, throttle, ride) on the Vulcan's compared. I'm not a fan of the vibes that are built in to the RK. Not sure if they've improved that or left it alone. I'd say most folks who like that bike, like the vibes and even bought it for that. Power was good, but easily overlooked because of the other factors that were blurring my vision (literally).

I've been scoffed at by a hand full of HD riders when I had the 750. The few that were allowed to ride my 750 were thoroughly impressed and never said a negative word about it afterward... It holds it's own with the best of them!

2005 RK compare

My friend has a 2006 Road King, stock with the 96ci mill. Who ever jumps first will be out front. If you go together it is dependent on the road ie..uphill RK downhill VN etc...on the flat he can just pull ahead. That being said, my vn winds up nicely while the RK feels almost ready to come apart over 5000 RPM IMHO. If he goes stage one it is over. If I go stage one it is also over. I will take my 1500.00 investment over his 22 grand any day. The guys who have taken the mods of the professor to heart can blow away a standard RK.

I would think the RK would have a very slight edge. But you will have someone on a RK looking next to them wondering how a little jap bike with half the motor is still hanging with him.

Close enough the advantage would go to the rider and not the bike. IMO.

Global warming? So what if my kids never see a polar bear. I never saw a dinosaur and I'm ok.

Yne 750 will take the line, buth the Road king will take you on the top end.
Tey have alot of power but that weight hurts off the line.
My Ultra has the same motor and it is really quick mid range and up.
Pluss he has that 6th gear whis is used at speeds of 65 and up.
I took mine to over 100 and did not use all that motor, Launched off the line hard one day and pulled the fron tire off the ground.
I was shocked for a 900 LBs bike and stock motor.

It would be a very close race. It would depend on driver experience and hole shot off the line.

If you get to any hills or if you are 2-up riding.. forget about it, the RK will leave a 750 in the dust.
The 05 RK is a great bike. Very comfortable.
In regards to fit and finish.. the RK beats out the VN1500
In regards to performance and smoothness, the VN1500 wins
In regards to ride comfort.. they are very similar.

Its hard to compare a little scoot like the VN750 to a HD touring bike with a 96CI motor on it.
A better comparison would be a HD Sportster 883.
