I played around a bit with that online dyno...

A 600-pound bike with a 180-pound rider needs 90 RWHP to break 12 seconds in the 1/4.

A stock Rock has 140 HP at the crank, which is about 1 HP per cubic inch. It is unlikely that Triumph's new 1500 will have more than 1 HP per cubic inch at the crank.

If Triumph does give the 1500 1 HP per cubic inch at the crank, that'll equate to about 91 HP, which in very generous terms would be 78 RWHP.

A 600-pound bike with a 180-pound rider would pull mid 12's in the 1/4, which is easily better than a Speedmaster or America.

I just can't see any of us captains, who are used to very nice performance, switching to a 1500. I do think Triumph could easily compete with Harleys if Triumph gives the bike 1 HP per cubic inch at the crank. I don't see the 1500 stealing from Rocket sales so much as destroying America/Speedmaster sales.
 
That is a niche that Triumph needs to fill though, 865cc to 2300cc is not much variety. And that is the range in which most cruiser sales are made in the US.

Good analysis. What's the point if it doesn't get more than 1 HP per CI. Might as well get a V-Max.
 
1500cc would fit in with a 2 cylinder rocket motor. Even sideways they would be wide. Maybe just keep it inline with the frame like the R3.
 
I heard from the Triumph guys at sturgis

I heard that a mid size is coming out and all I can remember is that it is going to be a belt drive I guess its true what ever is said in sturgis stays in sturgis ????? is that how it goes :D
 
Here is an "artist's rendering" of what they think it will look like...

There are plenty of 1500 cc bikes out there - Harleys.

However, if they doubled the size of the parallel vertical twin, I might consider it if it weighed less than 600 lb. and had over 100 hp. The Rocket is a bit of a moose for me when I'm not rolling. Great power though.
An 1800 V4 would dot it!!:D
