I follow what you are saying and agree with you too an extent.
And I COMPLETELY understand the cost factor in arriving there. Totally get that.
However, I would also counter (and I'm sure you understand) that power to weight ratio is far more beneficial to the rider when the chassis weight is less.
For example I'd much rather ride a 350 pound sled with 175 horse than I would a 600 pound sled at 300hp.
It takes more money to remove weight than it does to add horsepower, but it wasn't always that way.
In the old days, up until about 12 years ago, it took $100 for every pound to drop or HP to add.
It's not so easy to drop weight now when sleds are 100 pounds lighter than they were a decade or two ago.
We would buy heads, pipes and port/polish a sled for $1000 to gain 10-15hp (and that was a hot sled).
