What's so unique about the 06-07 Dyna that causes rotors like these not to fit? I checked the part number on the 2009 street bob and the OEM front left disc is the same as the one on the 2006 street Bob. Do these guys mean it won't fit any laced Dyna 06 and newer? or just something about 06-07?

Thanks.


See here where what I think is the same rotor is listed as OK for an 08-10 Bob, but not for 06 or 07.

I am looking for a five-point star-shaped floating rotor for the dyna laced hub. Not sure why it is so hard finding one.

 

I know the brake pads are different and IIRC the rotors are too. '08 and newer are floating rotors. The axle diameter is different also but I don't think that matters.

 

According to Ronnie's the brake disc didn't change when the caliper changed in '08. Caliper changed in 2008 ,but HD used the same disc until 2010.

My 07 came stock with a floating front rotor. Back isn't though.

 

They probably don't make that "Your brakes are dragging" sound we have all come to expect on our Dynas if used on those years.

 

 

Does anyone know if the 2010 front rotor will work in place of a 2006 rotor? I bought 2010 SB rims for a 2006 SB and was just going to use the newer brake rotors with the stock calipers. The rear rotors have the same part number but the fronts are different. Will they interchange?

 

It's because the rotor is 11.5". The front Dyna rotors on the '06 and up bikes are 11.8".

 

in 2008 they changed the size of rotors to match the new calipers that also came out in 2008
