LA Choppers Blackline Riser Adapter Kit For Harley Blackline If you've got a Blackline, it came with some funky bars. However, if you need to re-position them, regular risers won't work - unless you have these sweet adapters. Inserts fill in the existing handlebar mount holes, so conventional risers can be mounted. Features: Billet aluminum Gloss powdercoat finish Made in the USA
