Being fairly new to HD, but not M/C in general, I have an engine question. What is the real difference in the TC engines? I know the softails have the balancers, and the touring have the rubber mounted engine. Ever since HD came out with the TC balanced engine, I’ve wondered why not stick that engine in the touring bikes AND have the rubber mounts to make the smoothest engine known to mankind? (at least as far as big twins). I love my ’07 RKC, and have never ridden a TC balanced engine and wonder just how good those balancers are compared to the rubber mounts. I’m thinking the rubber must be better, otherwise HD would have put the balancers in the touring bikes. Friends have told me the softails will shake your teeth out, while a guy at work (who, as far as I know has no reference) says his Crossbones is smooth as silk. Then again, he may just be looking at my engine at idle and assume that it always shakes like that. Somebody out there has ridden both models of about the same year, so I’d like some info on all this.
