Hulk front brake on YZ125 (CRF + 320mm)


I have 06 YZ125 since winter 2009.


Bike is great but stock braking power is weak.


In autumn 2010 i buy oversize Braking 270mm floating wave disc rotor + bracket.

Stopping is not much better! But disc is new, not worn like OEM.


In 2012 i put 2007 CRF 450R parts: front MC, hose, hose clamp, and caliper+pads


But before few day i sell that system and put a new "monster" setup

320mm Motomaster disc rotor + 2010 CRF 450R front Master Cylinder, hose, caliper (same as 2007 parts)

Here is Motomaster 320mm adaptor for stock bracket, but i sell that adapter and made them (better) homemade :D



Need to make new hole (with thread) on stock 05-07 YZ bracket to use with 320mm


making lower mount support




and ready, steady, go


huge bitch


Stay tuned!

Holy crap, you have some muscle atrophy going on? I would figure the 270 mm, was good enough, and adding the CRF system (I have that as well) would even kill some factory bikes, but you went 11 here... :thumbsup:

That is nuts!! I bet it stops on a dime now.

no muscle atrophy here. I want 320 rotor, and it is unique. Wait for warm weather to test that monster brake :D

Just don't take it through any ruts or by any rocks.
