Honda CRF250RX Cylinder Works Big Bore Kit Ride Review

[@DirtZen]

I added the RedMoto 300 big bore kit to my 2019 250RX and it was a game changer. Highly recommend the big bore kits 👍✌

Just put a top end in my yz450f thanks to your vids. Fired right up, keep up the vids.

I can’t tell u how much I a soul it’ll love ur videos

[@aidanvelthuis1267]

I purchased one of these Honda’s, I love it and I planned on putting a kit in when my cylinder wears out, is there any other modifications that must be done to accommodate the kit, and is there any reliability issues when you install a big bore, any help would be greatly appreciated

[@Enuroracer222]

Any reason yall chose the Cylinder Works 270 kit rather than the Red Moto 300 kit?

[@ramonnavarrolage8810]

I have the 300 Redmoto and is top. I imagine Cylinder Works is cheaper and easier to get cause the Redmoto is from Europe.

Does the mapping switch still work with the big kit? I have a CRF 280 r big bore but the mapping doesn't work?

[@davidpalmer287]

Are you still using the stock ecu and if so is a remap required when installing the big bore kit?

[@jorgecantos5657]

I hace the same cuestión cause y put on mi bike and does not work

[@quadcityracing]

Tokyo Mods can remap the ecu

[@davidpalmer287]

@@quadcityracing that is where ive sent other ecu's in the past. I just wondered if its required for big bore. Ill probably just call tokyo mods and see what they think

[@quadcityracing]

@@davidpalmer287 yeah, you should remap. They did two 270 Crf’s for me, both ran perfect.

[@davidpalmer287]

@@quadcityracing what year model did you put the big bores in, and is it worth the money? I have a 2018 and just would like to have a little more bottom end power.

[@345Dion]

Stock ecu?

[@rmatvmc]

Yes, this is the stock ECU.

[@ramonnavarrolage8810]

This bikes are great but need heavier flywheel.
