Thanks. Was the freeway rpm difference noticable? My calcs make it more like 2.4 larger teeth on the rear, but that is splitting hairs. That sounds like what I was looking for. Forgive this newby question, but does changing the belt require removing the rear wheel?

Now I achieved what I was looking for and I honestly think this is the way the bike should have been put to market as the 50-70 mph range is where pretty much most of us ride.
With both the wife and I on the bike I find 5th is a more usable gear rather than buzzing round in 4th unless I’m on a freeway then you have good overtaking response.
As far as changing out the belt , you remove the rear exhaust and support bracket, take off the front pully cover and then take out the bottom bolt and loosen the top bolt of the exhaust side rear shock.
If ta dont have one already, it’ll be a good idea to get a work shop manual.

But now if you go with getting a larger rear pully ( and that’s if you can find one that’s 3 teeth larger to fit the sporty ) and don’t jam up with ya belt guard ETC )
The stock belt will do Nicely.
A guy that I used to ride with “ said “ he knew a guy 🙄 that knew a guy that knew a guy that put a 27 front on his sporty If ya believe that 🤥 , But is was a rev munger and only good for wheelies
Hope this helps ya out

Thanks and it does. I have to apologize as I no sooner posted that then told myself, "you have a manual, look it up". So I did. I was out cruizin today, had to make a run to town about 50 mile round trip. I was flowing with the traffic on the freeway at 80 mph and realized, this is this bikes sweet spot. Crazy smooth. Problem is that speed would surely attract unwanted company with many lights on their vehicles. Then I remembered this thread and thought I should get that smaller pully. That might bring the sweet spot down to 75 or maybe 70 right where it should be.
So this will be my next project. Kinda funny since the 883 guys want to gear up and you geared down and soon so will I. This bike is plenty fast enough for me but the low speed change will be welcomed.

Your going to need a tuner like the power vision to make an ECM adjustment to correct this.

Found this on a website somewhere, thought you might find it useful.
- 2004+ 883 models have a 34T front primary sprocket and 2004+ 1200 models have a 38T front primary sprocket. Both models have a 57T clutch basket.
- 883 models from 2004-2010 came from HD with a 28T front final drive sprocket, and 2011+ came with a 29T front final drive sprocket.
- 2004+ 1200 models came from HD with a 29T front final drive sprocket.
- HD also offered a 30T front final drive sprocket on certain international models.
- All 2004+ models, 883 and 1200, came from HD with a 68T rear final drive sprocket.
- Here are all the possible gearing combinations with factory sprockets, in order of shortest to tallest:
- (57/34) x (68/28) = 4.07 overall in top gear (stock 2004-2010 XL883)
- (57/34) x (68/29) = 3.93 overall in top gear (stock 2011+ XL883)
- (57/34) x (68/30) = 3.80 overall in top gear (XL883 primary with HDI final)
- (57/38) x (68/28) = 3.64 overall in top gear (XL1200 primary with 2004-2010 XL883 final)
- (57/38) x (68/29) = 3.51 overall in top gear (stock 2004+ XL1200)
- (57/38) x (68/30) = 3.40 overall in top gear (stock 2004+ 1200 primary with HDI final)
- From the shortest combination above, to the tallest, you would reduce your rpm at any given speed by about 16%, which is a LOT. For example, if you're turning 3000rpm now with the shortest combination, you'd be turning only 2500rpm at that same speed with the tallest combination

Not mentioned above, but the XR1200 uses the 883's primary ratio (34T front).
Also, be aware that primary side gearing changes will change how much torque you're asking the clutch to hold. The deeper 883 primary puts more torque to the clutch.
Although primary side changes won't affect the speedometer, they can play hell with gear indicators, if you have one. This can be fixed with a capable tuner device though.
And as already mentioned, final drive changes will change your speedometer reading, but again, it can be fixed with a capable tuner device.
