New member. Thanks.

I have a 2016 Heritage soft tail classic.

1. I was told it has a High Output 103 ci motor. What does that mean? how much more than Normal 103 and more of what? Horse power? torque?

2. What is the expected top end? Get to 100 pretty easily, but haven't gone further?

3. quarter mile time/speed.

I like the bike a lot have just passed 1000 miles on it.

thank for any help you give me.

 

84 views and no answers to questions? someone must know.....

 

I suspect the sarcasm won't elicit much encouragement to answer. Perhaps others, like me, are interested to know the answer as well and are viewing and/or watching the thread...

I do know that I've read that Harley doesn't really "do horsepower numbers". Since, like you, I just bought a 2016 FLSTC, I've been using this as a reference for most of my technical questions:

Perhaps that will help you somewhat. Beyond that, I'm a newbie to the motorcycle world myself (beyond some dirt bike racing when I was younger, but no wrenching), so I don't have much further info to offer beyond what HD puts out in that spec sheet.

 

you aren't getting many responses because this information is easily researched with some Googling. So I did the work for you. Your welcome.

1. I was told it has a High Output 103 ci motor. What does that mean? how much more than Normal 103 and more of what? Horse power? torque?
103 cu/in engine is larger than Harley 96 cu/in, which in-turn was larger than the 88 cu/in, which in-turn was larger that the 80 cu/in engine, etc.
A: In stock form it's around 70 HP and 85 ft/lbs torque. I say "around" because there are a lot of variables.

2. What is the expected top end? Get to 100 pretty easily, but haven't gone further?
A: This is not published, and is open to wild speculation. My guess is that it goes "poof!" into a vortex when you reach 88 miles and hour.

3. quarter mile time/speed.
Who cares? I didn't buy the bike for its speed (thankfully). zerotosixty.com lists it as 13.1.

 

Actually, I did not mean to be sarcastic, I apologize.


I found this on the internet , for what its worth:
Here are some number that your stock Harley…

Harley-Davidson Twin Cam (1450cc / 88” 45 degree single plug v-twin with F.I.) – 62hp & 77 ft lbs of torque

Harley-Davidson Twin Cam (1584cc / 96” 45 degree single plug v-twin with F.I.) – 66hp & 82 ft lbs of torque

Harley-Davidson Twin Cam (1688cc / 103” 45 degree single plug v-twin with F.I.) – 83hp & 95 ft lbs of torque
(after find below info this must be for standard 103)

Harley-Davidson Twin Cam (1800cc / 110” 45 degree single plug v-twin with F.I.) – 95hp & 110 ft lbs of torque

103 and 110″ Twin Cooled bikes Touring 103″ 76.40HP 90.20TQ 110″ 84.80HP 98.94TQ

another source:
HO is advertised as 104 ft lbs of torque at around 3250 rpm, compression 9.7:1.

difference is different cams for increased mid range performance and slight increase in compression.


YOUR NUMBERS MAY VARY.

HARLEY-DAVIDSON SOFTAIL 0 TO 60 MPH AND QUARTER MILE TIMES
2016 Harley-Davidson Softail Slim S 0-60 mph 3.9 | Quarter mile 12.7
2014 Harley-Davidson Softail Deluxe 0-60 mph 4.5 | Quarter mile 13.3

2001 Harley-Davidson Softail Fat Boy 0-60 mph 5.0 | Quarter mile 13.4
1999 Harley-Davidson Softail Compare mph 4.8 | Quarter mile 13.1


and this:
If you look in the HD catalog at the 103 Stage 1 and the 103 Stage 2 charts you will see that the 255 cams make about 5 more hp and lb ft. over the Stage 1 bike. From Harley's own Dyno results. The 255's are slightly more aggressive, at least on the bottom end, than the HO cams. This has made me really question how some people say a mild bolt in cam is worth 10 hp and 10 lb ft. on a 103. Not saying they are wrong. Just saying I am a little bit skeptical.
