    Sportster 883CC to 1200CC Conversion Kit is rated 5.0 out of 5 by 1.
    Rated 5 out of 5 by from 883 Stage 1 Kit I purchased a 2016 XL883N for my girlfriend last month. The bike was as expected for a 883 Sportster could cruise on the highway at 70 mph easily however it was a struggle at 80 mph. With 110 miles on the bike i had Naples HD install a Stage I 1200 kit, with a Sands 2 into 1 stainless exhaust. THIS BIKE TURNED INTO A MONSTER!!! After 550 miles i had it tuned and dyno'd ... 78 HP and 81 lbs of Torque. In 4th gear it will Scream from 60 MPH to 104 (rev Limiter) very very very very strong and very quick. This is with a 210 lb rider. You will not be disappointed with this upgrade! It will leave my 2016 stock softail in the dust. I would like to ad that with the upgrade the engine runs much smoother, with a much reduced vibration

    2006 883 to 1200 kit

    Can I still purchase the 883-1200 kit for my 2006 883R? I know I can get a aftermarket kit but I only want genuine HD parts... I just purchased the bike 10/11/2016, and this is my first harley. If I cannot purchase this kit still, I will either have to find every part individually or sell my Harley and buy a Indian. Will not sell my sport to buy another sporty.

    Asked by: Kimy12

    What will my Rpm read in 5th gear traveling at 100 kph or 140 kph?

    What real time results can I expect from this conversion kit? On my 2015 super low 883; while in 5th gear traveling between 100 to 140 kph my rpm reads between 3000 to 4500+. In similar fashion what rpm will the kit deliver in 100 kph or 140 kph?
