2017-2026 Honda CRF450R 102MM Big Bore 14.4:1 Piston kit

Description

Fits: 2017-2026 Honda CRF450R

The Dynamic Racing CRF450R 102MM Big Bore 14.4:1 High Compression Piston Kit is an absolute beast!!  This piston will work great for pump gas, MR12 and methanol nitro/funny fuel setups! Designed for high revving, high cylinder pressure and high horsepower, making this piston kit an excellent choice for drag racing, kart engines, flat track, ice racing and any other forms of racing where you want max power. We added horizontal gas ports for long lasting ring seal and reduced blowby. Expect an easy 6–10 hp and 4–6 lb-ft over a stock CRF450R if it’s sealed and mapped properly with pump gas. As with any modifications – power gains depend entirely on the rest of the build; head port design, valves, cams, and intake and exhaust… they all affect each other.

We do NOT currently have the cylinder and/or gaskets to go with this! YOU are responsible for getting a cylinder sleeved and ordering gaskets
