I think you make a typo error,, 2007 was when the 96'er's came out..
and I agree the next bump will be the 110 (standard engine)
Then if the Cvo's goes with the 120'' then (?) yrs later it will be the standard engine..
After that they may outlaw Bikes all together,, because of loud pipes. Bawwaaahawaaa...

So, is this a "size matters" thread ?
Just a thought, but self-pleasuring must be difficult.

There's a break even point on harley motors 88 to 96 inch is the sweet spot for them and I don't give a damn what the fanboys are saying once you go over 103" on them you start loosing ground mechanically. Lot's of basic geometry and math don't lie just look at the issues the newer 103's and up are having with heat, crankshafts and a few other major components going tit's up regular

93" is as big as you want to get with a shovel and still keep it civil and have decent longevity, They run bigger but the life span drops exponentially with every inch you go.

Todays motors the piston looks like the top 1-1/2" of a coffee can with an inch wide landing strip for a skirt, those don't do well with prolonged higher RPM's. One of the reason's the moco's been playing with the ratio's in the primary and the tranny so much , trying to keep those R's down. This in turn has lead to ever increasing problems in the primary with comp sprockets & chain wear along with bearing issues in the tranny's and few other things. Bigger the motor gets the shorter that piston gets to keep the engine the same outside dimensions , they want to get bigger an keep it reliable & long lived the motors gonna get bigger like the Victory's.

I will relate it to the Windows operating systems. Every few years Bill Gates needs a few more billion so introduces a new operating system. Was there anything wrong with the last? Shoot, I liked Windows 95. There were a couple bloopers but when I ordered a couple made for me computers last year I had Windows 7 installed. As mentioned, you can only go so fast.

My question is aside bragging rights and getting ever hotter ball cooker motors as they get bigger why does the new bikes need an ever bigger engine ? Speed limits are set in this country and nobody is pulling a mobile home with one.
Honestly aside throttle blippers at bike nights who actually uses a big motor to half it's potential as it is ?
