Handlebar Risers, Barbacks, & Bar Extensions 101 - What Do I Need to Know? August 03, 2017 11:03

We get calls daily from people who want to adjust their handlebar position but they don’t know where to start.

It’s really simple. To install risers on your motorcycle or atv you need to know 2 things:

  1. What is the diameter of your stock bar? Common sizes are 7/8" and 1 1/8" for dirt bikes, dual sport bikes, many street bikes, and atvs. For Harley & other V-Twin bikes common sizes are 1" and 1 1/4". Standing to the side of the bike/atv, simply grab a ruler [or a caliper] hold it up above the bar (near the bar clamps) and check to see what the measurement is going across the bar from side-to-side. Note: Rox risers only work on machines with a 1-piece [eg. tube] handlebar and top/bottom style bar clamps—they do NOT work on bikes with clip-on style handlebars.
  2. How tall of a riser can your stock cables handle? 99% of motorcycles on the market have enough factory cable to install our 2" risers, but most atvs can only install 1.25" risers before the cables will get too tight. Remember though, these are just rough guidelines. Some bikes can install 3" risers with stock cables and some can only install 1 3/4" risers with stock cables—if you are unsure how high you can go you can take a look at our fitment charts, give us a call at 218-326-1794, or you can do a simple check on your own. Remove the bar from the stock bar clamps. Find something to use as a spacer [a scrap board of 2x4 will work]. Place the spacer board underneath the handlebar and try turning the bar fully both directions. If your cables or wires seem overly tight remove any zip ties and/or cable retainers then run the test again. Repeat test until cables are relaxed through the complete range of steering motion.
