The package includes the needle and retaining clip. The listed model years describe the TokyoMods application recommendation; they do not mean NCYR was the factory needle in every year.

Customer and tuner recommendation context
TokyoMods recommends NCYR when a known CRF450X setup specifically calls for this R-model needle profile. Owner discussions document several different CRF450X needle-swap choices, so this page intentionally follows the TokyoMods NCYR recommendation instead of presenting a crowd-sourced universal setup. The stock needle code can vary and should not be inferred from the fitment range.
Before you order
Confirm the full NCYR marking or a known TokyoMods or trusted-tuner specification. Complete calibration depends on the engine, carburetor, fuel, intake and exhaust, altitude, temperature, jets, accelerator-pump setup, and clip position. No universal clip position or jetting recipe is supplied. Do not assume a rider's complete CRF450R-based jetting recipe transfers unchanged to a CRF450X.
Frequently asked questions
Was NCYR the factory needle in every listed year?
No. The factory CRF450X profile varied by year and specification; for example, Honda documented a different standard code for the 2005 model. NCYR is the TokyoMods tuning recommendation for the listed application.
What is included?
One Tokyomods Keihin NCYR jet needle and one retaining clip.
What clip position should I use?
Use the setting from the established TokyoMods or tuner specification you are following. There is no single setting for every motorcycle or condition.
Is this needle returnable?
No. Verify NCYR, model, year, and intended tune before purchase.
