● 79MM HOYAKI RACING PISTON SET FOR CBR250R / CBR300R / CB300F / CB300R... (OVERSIZE 3.00)
● High quality light weight 79mm racing piston with a heat resistant coating to fight engine knock and with build-in anti-detonation grooves.
● With this lightweight racing piston you get a higher compression engine which makes a better burn, and the cylinder displacement will be changed on the 250 engines from 249.38cc to 269.46cc, which goes on the 300 engines from 286cc to 305.65cc
※ Need to be installed with the 79mm Yuminashi Copper Head Gasket (LINK)
※ This piston is a KYJ piston type which was used on both the CBR250R and the CRF250L and M engines from 2011 until 2017, so you need to be careful if used on a 2018-2021 and 2021+ bike, and modify the piston or the head if required!...
※ Recommend to remove the restricted stock air filter box and to be installed in combination with the 360cc/min injector (a.k.a. "CRF450R injector") (LINK)
※ The 42.5mm Throttle Body Upgrade set is also available, and the details about this can be seen at this page (LINK)
