Kenny G: I am afraid I do not know, BUT go to the xena site and they have a measuring chart you can print and use to MAKE sure you get the correct product. It works great and the product is killer as well. Best Oct 10, 2014

Lyban I: I believe they come in different sizes. Best way to find if it fits is to measure the width of the rotor from the outer edge to the inner edge. That measurement should allow you to determine if it fits Jun 16, 2014

Alexander E: Use the measurement diagram that is supplied. It completely depends on the disc rotors mounted on your bike. I ride a Harley 1200n and it fits just fine. Jun 16, 2014

Randolph H: I would measure your rotors, and also the thickness. Also the throat distance where it fits over the disc is important. I seem to remember the website gave some info, but I went online to the Xena website for more details. I would also suggest you get a lanyard to hook on your handle bars so you don't try to drive off with it installed. TWICE!!!! Sep 17, 2014

Lukas J: Based on pictures of your bike I see online, the front rotor slots look pretty standard width. I too feel my slots are "standard" and the lock fits with room to spare. I would think this would fit your bike just fine. Jun 6, 2014

John W: I use this lock with a 2014 Indian Chief Classic, so don't know whether it will fit your bike. The most important consideration is the thickness of the disc...not the diameter of the perforated holes. When I use the lock with my bike, it goes through one of the pie-shaped cutouts in the disc.

Hope this is helpful and good riding!

Douglas H: Measure your disc thickness. This one fits my front but not the rear. I would prefer to put the lock on the rear but I ordered the lock before my Ebay purchase bike was delivered. I have yet to attempt to us the alarm feature. Even to install the battery you must endure the alarm being actuated. I am also afraid I will fumble the lock removal process and set the damn thing off early in the morning. I live in a small apartment complex and don't want to subject my neighbors to screeching unnecessarily. The every time you need to change the battery you need to go through the initiation of letting the thing go off. Would be nice it if the alarm function were more user friendly, but maybe this is just the most bullet-proof design available for the price. The lock does not come with the coiled plastic reminder cord that many locks do. If I had it to do again I might end up buying the same product again (with a larger gauge slot to accomodate larger rear disc) but I would do much more research on the alarm features of different options.
