the standard darkside tire

The big Rocket can chew up tires so thats one reason the CTs are chosen for high mileage riders

That it does! I thought my M109 & C109 went through some back tires. Both were big powerful cruisers with lots of torque and a heavyhanded rider. The Rocket goes through back tires a couple of thousand miles faster than both of those.
 
Riken Raptor 225/55 ZR16.
Works on a 2012 Roadster with ABS. Just don't let Triumph know it's on there, they won't do warranty work because of it.

Thank you...my bike is out of warranty and I wouldn't let dealer touch my rocket ever again anyhow.....
I was just wondering about the tire size difference and abs reactions...

Looks to me to be within an inch the same diameter as an OEM 240/50R16.
Should not affect your ABS assuming you still are running the OEM front size of 150/80R17.
I did the calcs awhile ago, but as I remember the circumference difference needs to exceed 8% of OEM for the ABS to stop functioning. I run a slightly larger rear Excedra Max at 240/55R16 and with a 130 front the ABS stopped functioning. I can get away with a 140 up front and retain ABS function.

Welcome to the Forum Holley Rocket Man, see you been watching for a couple years, you can also run a 245/50/16 it to gives you almost the same diameter to a stock tyre it will only just fit in the swing arm but gives new meaning to "Fat Bottom Girl"
 
HansO be correct.
FYI - if not too wide, that 245/50 would be .3 inch smaller circumference that the 225/50 and just .6 inch larger circumference that the OEM motorcycle tire.
Bear in mind that these calcs are also affected by mounting on the motorcycle rim width versus the intended car rim with.
This got me interested, so I checked and found that Riken Raptor is recommended for a minimum rim width of 7 inches. Since the Rocket Roadster rear wheel width is 7.5 inches, I would think it be no problema in the mounting department and have little affect on the circumference calcs.

I think you may have that backwards. The 245/50 would be taller, and the 225/50 would be the shorter of the three.

I had used the 225/55R16 size.

I see that the Riken Raptor comes in both a 225/55 and 225/50.
The 225/50 would be 1.86 inches smaller than the OEM and the 225/55 would be .93 inch smaller and the closest to OEM.
