Kit ATHENA BIG BORE 470cc for HONDA CRF 450 from 2017 to 2024

Here's the big bore kit from ATHENA to increase the displacement of your HONDA CRF 450cc 4-stroke motocross / enduro bike. This Ø98mm kit, as opposed to the original Ø96mm, takes your bike from 450cc to 470cc! You'll immediately feel the torque and performance gains. The average gain is 4 HP, which is enormous for this vehicle. It's more than enough to have fun on the track or in the woods. ATHENA has also thought things through, as this top motor is sold complete. It includes cylinder, piston, ring and all the gaskets you need for a quality, leakproof reassembly. The advantage of using this engine is that it is designed to be mounted on the original connecting rod with the original cylinder head and camshaft. So you don't need to make any modifications or adjustments! You'll find below a detailed list of vehicles on which this cylinder can be fitted.
