Im having a tough time finding a caliper to fit my 13 street bob 11.8 rotors. Ive searched on here and cant find a definite answer.

 

try looking for one for a 300mm rotor - i think that's the actual measurement

 

Ya it is, seems like a pia trying to find one!

 

Happy I got that right, I'm a'learning!
Have you looked at JayBrake, they have em...

Anyone know if it will fit a 13 street bob?? question is if im replacing a caliper and rotor can i change it to a 11.5?

 

Pretty certain it will, don't think much changed on the forks for a while... It's probably the left you want no?

Yup. If you're changing both there's no reason you'd have to stay at 300mm

 

See, I was thinking that it would NOT work because you're still mounting the caliper to the same mounting points. So, your pads wouldn't be lining up on the rotor properly. This is purely an assumption as I have no experience or knowledge of a swap like that. Hopefully someone else can chime in that knows more because I'm also a little curious now...

 

I was under the impression that you could buy calipers for 300mm or 11.5" rotors, at least that's wha the jay brake site led me to believe...

I'll happily defer to someone knowing more as I'm about to make a purchase myself and could happily avoid an $800 mistake

 

From JayBrake website:

Jaybrake's J-Six are designed to mount directly onto Harley front forks (except Springers) without having to change the brake lines. They are designed to fit 2000 and up with 11-1/2", 300 mm and 13" rotors. They are available in Extreme or Ultra designs

11-1/2" & 300mm Rotors:
MSRP: Polish $379.95, Chrome or Black Anodize $399.95

13" Rotors:
MSRP: Polish $389.95, Chrome or Black Anodize $409.95


Looks like the same caliper is used for both 11 1/2" and 300mm (11.8") rotors. Which makes sense since if you look up the Harley part numbers for calipers used in 2005 with 11.5 stock rotors and 2006 with 11.8 stock rotors they are the same number.

I am by no means an expert so don't go spending $800 before you confirm this though, lol. Im sure if you call Jaybrake they can confirm.

Heres a link to the JayBrake page: http://www.jbrake.com/brakes_extreme_ultra.html

 

I just found this in their catalog as well:

Note: FXD models having 300mm rotors use caliper for 11.5” rotors

They do however make different calipers for 11.5" and 300mm rotors.
