Engine size info
 
I am a NewBee and looking for some basic information. I now own a Royal Star 1300 but I am looking to purchase a Road King in the near future. As I look around I am seeing a wide range of engine sizes and would like to know if there is really a big difference between the various sizes. I have seen 96cc, 110cc, 103cc, twin cam, 1450, 1540, 1690.....? Thanks for any info provided

Interested in the same I bought a 1200 forty eight sportster. And looking to MAX it out. I don't know the engine sizes and options.

96, 103, and 110 as well as 80 are all cubic inch (CI) sizes of various Harley engines. The larger numbers (1300, 1450, etc) are roughly the cubic centimeter (CC) equivalents of the CI size.

So what is the the Max bore out on a 1200 sportster? And insurance said it is a 1202cc...

That's right. 1200 Sportsters are 1202 cc. 883 Sportsters are 883 cc.

Sportsters aren't generally spoken of in cubic inches. The bigger bikes are. The 80 inch Evos and the 88 inch Twin Cams are sometimes referred to by the number of cc. The newer 96, 103, and 110 motors are almost always referred to by their cubic inch size.

80 cubic inch - 1340 cc
88 cubic inch - 1450 cc
96 cubic inch - 1573 cc
103 cubic inch - 1687 cc
110 cubic inch - 1802 cc


There are a lot of differences between the motors. 80" Evos have a single cam. The rest of the "big twins" have twin cams. Obviously the larger the cubic inches the more power and torque you get.

Now, the Sportsters have 4 cams. They always have. Even back when the Ironheads were being made. Ironheads were 900cc and 1000cc. On the note of old Shovelheads, they came in 74" (1200cc) first and then 80" (1340cc) later on. The Evolution motors came after the Iron and Shovel motors. The twin cam motors replaced the single cam 80" Evos in 1998 and the Sportsters kept the smaller quad cam Evo motor going. They still have quad cam Evo motors in the Sportsters to this day.

Hope this info helps.

  • 88 cubic inch - 1450 cc
  • 96 cubic inch - 1573 cc
  • 103 cubic inch - 1687 cc
  • 110 cubic inch - 1802 cc

Just to add to Rohan, all of these are twin cam, big twin motors. (as he mentioned) The design is essentially the same. The difference is in the model year.

88" - first twin cam. It started in 1999 (2000 for Softails)

96" - Second generation TC. Started in 2007. Same bore as a 88" but longer stroke.

103" - Latest TC. Sock motor in 2012. It was available as an option on some bikes earlier. Same stroke as 96" with bigger bore. There was also a 103" on earlier Screamin' Eagle bikes.

110" - This is the CVO motor. Same stroke as 96"/103". More bore.

Any of these motors can have the displacement changed remarkably easy. There was Harley big bore kits that take an 88" to a 95" and a 96" to 103." The aftermarket guys have tons of other options.
