    Ok i'm confused. So the caliper mounting on the 85/150R/250/450 are all the same?

    no they are not

    applied makes a re locater (carrier) for the larger caliper and over sized rotor...there is a DIFFERENT carrier for the stock caliper and over sized rotor.


    curious to see if it all works on a 12" bike.

    I am hoping it will. The QTM setup uses two piston calipers and it fits.

    To amplify what scottiedawg said, the CR85 and CRF150R use the same caliper mounts for the stock single piston caliper. Applied racing makes two different types of caliper adapter carriers to allow the CR85/CRF150R to use the CRF450 (and many others) stock two piston caliper. The options for the caliper carriers are to use either the stock size rotor or a 250mm rotor.

    Reviving a thread here - anyone running 17's on a CR85, are you running 125GP slicks on the front stock rim by chance, or what other options are you exploring. I think moving to a 12 or 14" wheel isn't an option for me, and I'm not sure the 90 will fit on the stock 17x2" rim up front. And I can't imagine everyone is busking up for Excel rim replacements etc...

    All input is appreciated...and keeping to the topic - keeping the 17" up front gives me more brake conversion options for sure!

    Yes I ran the stock 17 front with a 125GP slick on it. It was fine, there are all reasons why a wider rim is better but like I said it was fine with no issues, I did run a wider rear though. You will need the extended swing arm for the rear 17 I have one if you need one. Im back on 12's for now.

    That's super helpful - thinking of lacing a front 17 hoop to the rear hub and running 90's on both. Curious why you went back to 12's? Weight? Isn't the bike twitchier with that setup?

    Thanks again for the feedback!

    I wanted to try 17's and I loved them very stable. My 12's had old tires and were losing traction, I ride on a smaller cart track VIR so the 12's are ideal. I feel the 12's will spin up quicker on acceleration out of tight turns where the 4strokes pull slightly on me. I have new Savas on the 12's but unfortunately missed the season due to 2 shoulder surgeries from a dirt bike wreck. I would lace a wider rim to the rear for traction, these 85's will fly through a turn!

    Well I only ride on small kart tracks too, but I think I'll definitely want the stability of the 17's. Thinking a 90 on the rear should provide enough meat given it will be a slick and I'd like to avoid adding even more weight back there with a wider rim and 120 ya know?

    Wonder what your lap times say on 12's vs. 17's?

    Hey Tepco - curious - did you have any chain clearance problems with the 17" rim on the back? Did you put a 2.5 back there, or a 1.4 to match the front?

    Im running a 2.75 rear with a 125 GP 120 tire on the 17 and a 2.15 with a 120 on the 12's no chain clearance issues at all.

    What brand rim is that 2.75? Excel makes a 2.5x17, but I haven't seen a 2.75...

    Thanks again for all the feedback!

    Default CR85 17" wheel with 320mm rotor and dual piston caliper

    Does anyone know how to get a 320mm rotor to work on a CR85 with 17" wheels. JLF88 did exactly what I want to do and has pictures of his front wheel earlier in this thread. He seemed to use a hub attachment that allows the 320mm rotor to fit on the 4 bolt hole hub. Where do you get that?!? Thanks

    Motomaster sells a 320 rotor that fits the CR85/CRF150R. They also have the adapter needed to mount their 4 piston caliper to fit the 320 rotor. I used this setup on my CR85 and moved it over to my 150R when I changed bikes.

    Default ebc

    Hi, Thanks for the note. I ended up going with the EBC 280mm. The motomaster 320 only worked with their master like you mentioned and it was way too expensive for my budget. I bet those brakes are incredible! Thanks again.
