Well the new motor is really the M8b motor if you want to compare it to TCs. My bet is that if they try to commonize the sporty, it will be with the new street 500 / 750. Make it 900 / 1200 ccs and dress it differently.

No need for a B motor so the Softails and Dynas will share a common core frame area.

Sporty will ill get a refresh too but will keep EVO 883 and 1200 engines.

Street models will expand with the vrod engine in a new model.

I'd like to see them take another crack at these..I'd be first in line..old racing buddy of mine from back in the day has a near mint one, worth about $10K..they weren't competitive and were short lived but how cool it would be to own one

Think about that next time you get on a commercial airliner.

Sure, they go thru a lot of maintenance checks but still - great argument for aluminum frames.

:-) I'll probably still prefer steel motorcycle frames though

This is common knowledge, and has been known for decades: Every time a commercial aircraft pressurizes and depressurizes, the skin flexes. This causes work hardening of the aluminum, and that makes it prone to cracking. That's why there are regular inspections once an aircraft has a certain number of takeoffs and landings.

And it will be black. You heard it here first.

Ok the claim is that any stress will eventually cause aluminum to fail. What structural / material property of aluminum causes this failure? Common knowledge would would mean that it is likely documented somewhere.. Or is it simply and old wives tail / popular misconception.

It's not a claim, it's a fact.

We're not here to educate you. Nobody cares if you believe it or not. There are readily accessible FAA documents on aircraft inspection requirements. Google it.

I thought everyone knew about "work hardening" of aluminum. Guess not.
