UOTE=hig4s;7936271]I rode for many years two up on a 650 twin with no problems, and did fully loaded touring (added hard bags and trunk) on an 81 750 that had only a little more horsepower and less torque than an 883 with no problems.

Unless you plan on fully loaded touring two up, you will never need more power. You may want more power, but you won't need it. Actually if you do much two up riding you may want extra room more than extra power.[/QUOTE]
Well said and I totally agree

 

*u** that, that extra power is great. on the highway it's great.

right before i converted to 1200, i rode from baltimore, md to daytona, fl to tallahassee, fl and back to baltimore, md. the trip made me want to convert. highway power way the main reason. the ability to get out of my own way and jump from 50 to 100 in a blink.

i made a trip from tallahassee to key west and back in 24 hours and *u** if that 1200 didn't make that trip a dream.

truth is "do it."

 

Aside from the sprocket difference, isn't the tranny gearing different on an 883 Iron vs. a 1200 48?

 

yes...

I believe the 883 and 1200 use the same trans. The only thing different in late models is the primary sprocket. The 883 is 34 while the 1200 is 38.

Just looked them up on a 2014 superlow and a 2014 48. The part #s are the same.

Along with the primary sprocket, it looks like the primary chain has a different number of teeth, as well.

Can anyone find anything else that would explain the differences in gearing between a 2017 883 Iron vs. 2017 XL1200?

Thanks

 

The primary chain has to be longer because the primary sprocket has more teeth. I changed my 883 to a 38 tooth sprocket and also put a 96 link primary chain when I did my 1250 build.

I believe the front sprocket and chain is it. The belt sprockets are the same. I compared the trans gears and they are the same. I would post them but my scanner is down.

Also if you change the primary gear on an 883 to a 1200 gear. you will loose your gear shift indicator. I had to take a 1200 tune and import my 883 values using a power vision tuner to get it back. There is a table that controls this in the tunes that power vision cant see.

 

Today I bought a 2017 883 Iron, and this the exact type of info I'm looking for.

1) Does just changing the sprocket & chain now make the 883's gearing identical to that of a 1200?

2) With the sprocket/chain swap, how much of an RPM drop do you now get at 75MPH?

3) The stock 883 engine is pretty smooth. How much street manners (idle quality, etc) do you loose when going to a 1200 or 1250, if any?

4) Having already done the conversion, is there anything you would have done differently?

Thanks

 

See replies above. about the engine balance. Harley balances the 883 and 1200 right in the middle. Hammer makes their pistons right where Harley makes the balance.

Don't forget if you change to a 38 tooth sprocket you will loose your gear change indicator in your speedo. If you have a power vision tuner and send Hammer your tune they can fix it for you and send it back. You just install the new tune and you are good to go.

 

This 883 ->1200 conversion now has even more appeal.


Do you know if a TTS tuning module has the ability to fix the gear indicator?

Thanks
