FAQ – Road Star

Frequently Asked Questions (Road Star)

I am part of the Road Star Clinic Online Forum, Road Star Clinic Facebook Group, Yamaha Roadstar Riders Facebook Group, Custom Roadstar builders, parts and trade and the Road Star – Parts & Bikes Facebook Group. In each of these groups there are common questions that are frequently asked and answered so I thought I would create a list of said questions and answers to help novice & experienced Road Star owners. If you have a suggestion for a FAQ that I left out please feel free to contact me and let me know so I can add it to the list.

Handlebars & Cables

Q: What are the tallest handlebars I can add to my Road Star without having to change the cables?
A: There are three cables and one brake line to consider. The specs on the OEM handlebars for the Road Star is as follows:

– Road Star Height 7″, Pullback 13″, Total Width 33″, 1″ diameter, Center width 8”
– Silverado Height 8″, Pullback 13″, Total Width 32″, 1″ diameter, Center width 8”
– Silverado S Height 6″, Pullback 13″, Total Width 32″, 1″ diameter, Center width 8”

Short Answer… Based on the feedback I have seen, you can install bars with a height of 10″ and still use the stock cables. Some owners have indicated that you can install 12″ bars and still use the stock cables. This may or may not be true of the brake cable. If looks are important then you may want to increase the length of the cables.

Long Answer… Since every bar is different, the best way to determine what size cables will work is by installing the new bars and using a string to measure from each connection. You will want to ensure that the push/pull throttle cables aren’t too tight, as they may not allow the push/pull action that is necessary.

The bars on the Road Star are 1″ in diameter. You can use larger diameter bars but you will need to ensure that they taper to 1″ at the risers and the hand controls. To use the OEM grips and controls you will need at least 7.5″ at a minimum. The Road Star comes with weighted handlebar ends. You can follow these directions to adapt them to your new bars and add up to 1″ depending on how you set it up (1/2″ by default). Keep in mind that if they are knurled (unnecessary for the Road Star), they will show if they are made for a Harley and you don’t have the one piece risers.

Your cables (new or used) should be lubed on a regular basis with cable lube. Motion Pro and other companies make a cable lube tool to do this. Lubing them will ensure they will stay functional for a good long time.
