Important: The Ninja H2 SX BrockFLASH ECU Stage 1-F increases the peak RPM limit to the same 14K peak limit as the Ninja H2R (actual 14.5 on tach). This increase is responsible for a large increase in power on these machines. Since the H2R has an accelerated maintenance schedule for increased RPM use, Brock’s Performance suggests that high rev’s be utilized under race conditions only. This RPM threshold is set so the owner can have access to full power, if desired. This does not mean the owner is obligated to rev the bike this high.

    • BrockFLASH ECU Stage 1-F With Fuel Tune (For Slip-On) Ninja H2 SX / SE / SE+

    Posted by John M on Apr 29th 2020

    The process was very easy and the product seems to work great now, I put in the ECU and started the bike and could not get it to run properly even though there were no check engine or trouble lights. I did follow the clear trouble process and it seemed to clear up my issues. I would have liked to get a Brock's sticker or catalog with my purchase as well just in case I want to buy additional stuff, hint!

    The ECU flash was a great upgrade for my H2 SX. It’s like I have a new motorcycle. It’s night and day with this ECU flash. The bike is pulling the front wheel off the ground at 100 mph.....
