Does anyone know if a 2015 brake rotor will swap over to a 2017. I have an opportunity to get a set of floating rotors for a good price but they are for the previous model. Thanks for you help in advance

Sizes will be the same at 320mm diameter and 5mm thick. Waiting for my Internet to get back on but the OEM part number for 2017 is 9330906000 the reference of the aftermarket floating rotor should read: compatible with this OEM code.
As far as I am aware the only difference besides the other diameter (280/300/320) id the number of holes.
The earlier Dukes had 4 and the later 6 holes.
The OEM code for 2015 is 90109060100, so there will be a difference.

I have an aftermarket 320mm Galfer rotor on my 2016. It required spacers and longer bolts for the caliper.

Original equipment was 300mm.

Ok so 2017 is a 320 right from the factory.

I don't think that will work.
I have fitted a Moto-Master Flame floating rotor (300mm) on mine (front) see:
A 320mm rotor (floating for an EXC450 is this one:
I have not compared the measurements but feel free ;)



One more question. Are the dirt bike rotors the same as long as they are 320mm? If it fits a LC4 or a exc 450 wonder if it will fit out bikes
