STAGE 1 - RYKER 900 ACE - Precision EFI
STAGE 1 - RYKER 900 ACE - Precision EFI



Regular price $298.00
The Precision EFI Stage 1 adds 15hp to your Ryker without changing or adding any parts, and run on pump gas.
We almost doubled the throttle precision and response while  keeping fuel economy at cruising speed
This reflash keeps the 3 mapping modes:
The ECO and Standard modes keep the OEM mapping while the Sport mode gives you the impression of riding a completely different machine. Your Ryker becomes much more responsive and above all, less restrained with the traction control disable.
But your Ryker remains as safe as possible thanks to the OEM stability control which remains operational in all mode.

While it is not risky to run on regular gas for the reliability of your engine, to get the full potential of your Precision EFI Reflash you must use 91 octane pump gas.
***We suggest the addition of our modified helix cam for the CVT transmission which greatly improves its response and allows you to fully experience the sensations of the Precision EFI Stage 1
