Fr2-02 system error

[heagachongoose]

08 1125r 4.5k miles, Out enjoying a nice easy ride when the engine light pops on and flashes fr2-02 system error. It went off after a few minutes. Stopped and ran a check, everything seemed fine. Drove it the 10 miles home with no issues. Anybody know what fr2-02 means?

Any ideas at all???? Bike runs fine with no issues. The code hasn't cone up again but I'd still like to know what it meant.

sounds like front o2 sensor threw up a code

do you have factory or aftermarket exhaust?

Bike is completely stock. No modifications at all. It is a California model though. I found out that a fr2-02 transfers to a po132 which is a rich mixture error code.
