Default torque on Softail vs Dyna

Why is the torque on a softail approx. 5 ft lbs lower that on a Dyna? Aren't they the same engine? Is the difference noticeable?

Thanks,
Larry

Softails have counter balancers which makes the engine a bit slower to rev. Certainly not big enough reason to choose one over the other.

The gear ratios are different

In addition to the TC88B counter balancers, the engine is rigid mounted. The Dyna is rubber mounted to compensate for its vibration I I beleive you get a few more horses.

the gear ratios and engine mounting have no influence on the output numbers that harley states. those numbers are taken on an engine dyno. meaning the they are testing just the engine alone. this is not rear wheel power, it's taken at the crankshaft and the engine isn't even mounted in a bike while they test. as far as why the numbers are different, i belive it to be a conspiracy to tick off softail owners

I test rode an 07Super Glide and Softail Standard back-to-back over the same course andopened them both up as much as I could to compare performance. I did notice slightly more pull from the Dyna during hard acceleration. However, the heavy vibes from the Dyna turned me off and I fell in love with the Softail. I ordered up a Train and I'm loving it.

It takes torque and HP to turn the counterbalancers in the softail engines.

Deadeye,

What were the reasons you went with the softail? The vibration you mentioned is it only during hard acceleration? How does the ride of each compare? I am debating between a Softail Std and a Dyna Custom or Lowrider.

Thanks,
Larry

Yeah I didn't think before I typed, it is engine torque not rear wheel.

The rubber mounted motors vibrate more at idle (good thing in my opinion).
After that there is not a huge difference either way.
