I'll post the info i was looking for on reviews.
1) im 5ft8, riding position is about the same as far as my lean forward with stock bars but my hands are about 1.5 - 2 inches higher.
2) no cable change needed.
3) bike handles much better with the smaller grip width. I go 95+ at times. (Sportster)
4) I took slack out from above the front fender and relocated my front brake line. Only cable you need to adjust to ride. (Pictured)
5) my check light came on after install. Took to dealership they checked it corrected it and sent me on my way no charge.
6) was thinking apes with forward controls, so glad i didn't. That's for another bike later. Not for a sportster.

These bars look hot on my 48. high quality steel and weldings. Actually feel sturdier than stock HD bars. Can be installed with stock wires and lines, at least on sportster models. (exempt maybe the 72).

I did a lot of research before deciding what handle bars to buy. I honestly wanted some 12" ape hangers but was quoted $1,200-$1,300 for parts and labor, and that's at a shop not the HD dealership. I decided to purchase the Biltwell Keystones and I feel that my bike took a upon a new look. They're definitely more aggressive looking than the stock and my arms rest straight out when riding. My only concern or heads up would be that on my 2015 Iron 883 the front brake line that goes from the bike to the handlebar is a far stretch. I had to remove the bolt from the frame in order to give the line a little wiggle room, otherwise it was going to be very tightly held and it concerned me. I'm not sure if loose or tight is best and I'll be doing more research on that. Aside from that the fit was awesome and the installation was pretty easy. I saw a few YouTube videos on it and it took me about 2 hours, 45 minutes of which were spent removing the left handle grip on the stock handlebar. Not bad considering I don't really have experience on working on motorcycles.

I wanted some different bars to compliment some tank fab and new paint but didn't want to drop a bunch of money having to get new cables for mini or taller apes. These Keystones are pretty much as tall as you're going to get without changing at least the brake line. It was tight getting my controls back on, but it all worked and I used all the stock cables and brake line. They look great, feel great and are a pleasure to ride behind.

I have a 2013 XL1200C

These bars are great if you want a very aggressive look. They could use a bit more pullback but they are a comfortable height. On my 2013 iron 883 I removed the brake line bracket at the top of the triple tree. This gave me enough line to use the stock controls and all.

I was going to Go with drag bars for my Harley 48 sportster. But after looking through many YouTube videos I decided to go with the Keystone Biltwell bars. I'm very happy I did, they have a great feel and are the look that my Harley Davidson 48 needed.

These bars look great on my (now former) Iron. Great styling and always get compliments on them. Great price for great bars. Paired with Avon grips best combo out there.

These bars look awesome on my 15 iron. They changed the riding position to a more aggressive forward position which I liked coming from sport bikes. These are well made and the shipping was quick! took me about 20 minutes to throw them on my bike and I was able to keep all of my stock cables!

Wanted to get rid of the stock bars on my Sportster and I just loved the aggressive looks of these. The ride totally changed too. I lean more forward, head into the wind, flying down the road. Turning has improved as well.

I did have to move the mirrors back up top. I just couldn't see a thing with them after I installed the Keystones in the under position.

I was also able to use the stock cables with no problems.

I highly recommend this product. These bars are super sturdy and have a very nice weld on them. The finish is smooth and sleek. I ride a black Nightster, and these bars have given it an amazing look and feel! I have gotten tons of compliments on the bars. Easy install; make sure to get the dimpled bars if you have the standard Harley controls.
