Picked up a fresh Honda CRF 450 a few weeks ago. Have been enjoying it so far, with one issue that is still bugging me: when rolling the throttle on the engine feels very abrupt/jerky. Feels like a badly jetted 2-stroke that is surging.

This is mainly a problem in flat turns and rutted corners; places where a smooth throttle hand is important.

I have turned the idle up quite a bit and that helped some. Primarily have adapted by giving bigger throttle openings and feathering clutch more.

Have read that remapping (send off or DIY) will help. Have also read that some exhausts will help. Any others have this problem and potential solutions?

I would suggest a remap. Tokyo mods does it for $100 and im sure they will give you more power over your stock map.

Also just a note, if youre riding a bike too slow for the gear it can get jerky. I experience this on my street bike if a car is dropping anchor lol.

Check the TPS setting. It may be set too lean.

Thanks for the replies. Will check TPS setting.

This sensitivity happens in all gears and is worse in lower gears (harder lurch in 2nd vs 3rd). It's almost as if it is tuned to be ultra responsive, but for a bike with this much power, it's not really a benefit (IMO).

TokyoMods was top on the list for remap.
