 Product Description

buying-2-discount-300pxl-.png● 80MM HOYAKI RACING PISTON SET FOR CBR250R / CBR300R / CB300F / CB300R... (OVERSIZE 4.00)

● High quality light weight 80mm racing piston with a heat resistant coating to fight engine knock and with build-in anti-detonation grooves.

● With this lightweight 80mm 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 276.32cc, which goes on the 300 engines from 286cc to 316.51cc 

※ Need to be installed with the 80mm Copper Head Gasket
※ If the compression is too high, then you can install a second cylinder base gasket...

※ This piston is a KYJ piston type, 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)

  • 1 x 80MM PISTON
  • 1 x 79MM PISTON RING SET (LINK)
