Back when men were men, Harley engines displaced 74 cubic inches, up from their original 61 inches.

During this period there was a common upgrade making those motors 80 inch strokers. Punching out every square inch might make a shovel 92 inches, if the beast could get enough oil.

Then came the 88s. Betty got a 95-inch upgrade. But here's my view. I doubt any of us have enough sense to find out just how fast Betty will go. I can't. I've never hit the rev limiter in fifth gear.

Now, say what you will, but the 96-inch engine was an attempt to regain power and still make better EPA numbers. You could get a 103-inch engine on CVO models. Now a 103 is common, but you can get the 110-inch engine any number of ways. (And BTW, my shop has admittedly put five 120R engines in street bikes.)

So here's my question. Now that 103 and 110 engines are available to the masses, when will the next big thing arrive? When will a 'green' legal 120-inch engine be announced in 'The Enthusiast'? It's either JIMS or S&S that already offers a 120 or 122-inch engine that runs on pump gas. And since most of us like air-cooled engines, when will the detuned 120-inch beast make its debut?

Whether we need it is immaterial. The claim is that a +100 inch motor is needed to pull three wheels. BS. A 45-inch flathead did quite nicely with the old ServiCar. Unless you and momma each weigh 300 pounds (possible from what I've seen) or you routinely do the ton with your Tri-Glide, these motors are strictly for bragging rights.

I believe the legal 120R is coming, possibly first to a CVO. The only question is 'when.'
