Moto-House MX – Performance Package, Performance Upgrades Engine Mods Accessories for Yamaha YZ250. Moto-House MX can make your Yamaha YZ250 run out front of the competition, KTM 250 SX, KTM 250 SX-F, Suzuki RMZ250, RM250, Yamaha YZ250F, Kawasaki KX250F, Husqvarna TC250 and Honda CRF250R. With our package, the bikes stay reliable and won't. So I'd like to upgrade the front brake on my 2016 YZ125. So far I have an oversized 270mm front rotor, ... but so far I've only found some about the yz250 and a lot on the yz450f. I'd like to hear people's experience on the Honda master cylinder switch.
