The A vibrates less than the B at speed. What you are feeling on the tourers at idle is low frequency vibes at low RPM. The higher frequency vibes at higher RPM are absorbed by the rubber mounts whereas thevibestransferright though to the frame on the solid mount.

I have a Street Bob but if someone gave me a B with a Deluxe wrapped around it I would probably take it.

Hard mount feels more like a motorcycle to, unless you're cranked up to about 105.The it feels like a runaway jackhammer.The little 4"x3" mirrors (on apes) look about 4ft X 3 ft. But, I loved the crap out of the thing. She's no longer mine (I screwed up!). Old fart.

ORIGINAL: kmm

Number 1 Counterbalancing consists of a different crank ( Heavier crank than the A motors)

Number 2 More weight less power (thats why the B motors are in the soft tails not the touring bikes)

Number 3 Centrifigal force makes the B motors buzz thru the the floorboards due to the heavier crank

Number 4 A motors shake at idle , B motors dont

Number 5 As for The post that mentioned rubber mounted engines get more power to the ground how come MOROSO and tons of drag racers all run SOLID

mounted motors?

Number 6 Come to the table with some knowledge
#5 - Drag racers run solind mounted motors WITHOUT a counterbalance.

See the irony in your knowledge comment?

I demo'd an Ultra Classic last Sat. I thought the vibration at idle was very cool.

I like the balanced motor in my 07 FXSTC, However, that balancer does soak up a couple ponies and foot pounds of tourqe. the best deal is have one of each.[sm=americanasmiley.gif][sm=drooldude.gif]

The quote regarded rubber vs. solid mounted to get the power to the ground and stay in place

I have owned 5 V8 Vegas I know torque

As for counterbalancing small blocks the 400 small block was so countered balanced it was EXTERNALLY balanced same with the 383 stroker motors

I've owned both and prefer the rubber mounted engine for many of the reasons mentioned above.

That "shake" when at a stop light is mystical.

At 52 I'm not sure which is best - thinking about it briefly I'd err of the vib and shake as its gives me a good excuse not to service the ol' lady when I can't feel anything from the waist down!
