The instructions were simple, you do need to be familiar with how to take off and put the throttle cables back on, but that's really simple. There are youtube vids on the subject. You will need something to cut off the glue tube tip off and the right size allen wrench to tighten, lock-in-place, the clutch side grip. After installation the new grips were MUCH better than the OEM set! Look really sharp and feel solid, and give a solid grip without feeling harsh on the hand. Unlike the popular kuryakyn ISO grips, they don't feel "squishy", nice and "SOLID". My friend bought some really expensive HD grips that were very similar to these and these were MUCH less expensive. I expect long wear judging by the quality. My grips arrived 2 days earlier than stated, so I was really happy about that too! Ordered on a Saturday evening, website stated delivery by Thursday, and got them Tuesday same week!
