Fast shipping! Excellent quality!


Looks nice, installs easy, just have to finish rebuilding caliper.


Fits Perfect and looks great. Didn't come with direction had to get torque values out of shop Manuel. Goes on easy!


very nice piece no problems with install my bike is a little hard to fine parts for 1st year with a 5 speed


Correct replacement, easy installation, show quality chrome, very fast delivery. Thanks so much, will be shopping with you again.


Good quality and finish. Includes a particularly comfortable contoured brake lever. Somewhat tight fit on chubby (1 1/4) drag bar primarily due to the curvature of the bar.


The front master cylinder fit and finish is terrific. I encountered no problems installing this item on the bike. Although, I did have a question as to why I had to use DOT 5 brake fluid. After I E mailed customer service and posed the question as to why, I received a reply explaining the reason. Not only are the products top notch, but the support is also. Thank you.


Easy to install,great look and fit.Only wish they sent instructions


Quick, easy and the right part.


worked fine and quaility seemed good


The product was excellent and the service was outstanding - very, very helpful!!!! Thanks to Angelo and Dennis (techs) they did everything for me and provided detail explainations of my questions. I am very satisfied!!! GREAT JOB!!! Thanks again, Ric


Nice part. Like the sight glass.


I have a 2003 Spirit and this product was same look as original. do believe it is better qulity. I saw the same type master cylinder on ebay and people were paying double the price I payed. J&P has a few nice parts still for Indians at a great price.


The product is high quality but there is no brake switch included.
