Very easy to install on in about 30 minutes. Buy extra set screws for the left hand grip their black and I dropped it on blacktop driveway. Like looking for aneedle in a haystack. Called company gave me the size and went out bought replacements. Tech support was very helpful. Look great 2010 883 Iron
Highly recommend performance machine Renthal Wrapped grips. Really good quality and looks super good! I have a medium to large hand and they fit my hands perfectly. Realizing more that the Harley Stock grips were really too big for my hands. The only downside of the grips is that the throttle grip is a little loose and so when your motorcycle is idling it'll rattle some. I found some tips on-line of how to lessen that rattle.
Easy install and the quality of these grips is excellent. No flaws in the chrome and the Renthal rubber is of great quality and super grippy. The only way you'd get a better grip is to glue your gloves to them. I am very happy with this product.
