Brass Balls offers the Keg and Step risers as a replacement for the stock risers on your Harley. Both accept 1" diameter bars. Keg risers have a 2" (51mm) outer diameter, 2 1/2" (63.5mm) high, give a 1 1/4" (32mm) handlebar rise and also feature a bolt-through mounting as found on FXSTS and FLSTS Springer models, but will also fit most other models when used with longer 1/2" bolts and nuts. Step risers are 2" (51mm) high, give a 1 1/2" (38mm) handlebar rise and have a 1/2" thread as found on most stock models. Sold in sets and come with required hardware.
