Ok guys,

I was tempted and I traded in my XB12sTT for an 08 1125R....the price was to good to pass up. The 09 is supposed to have different spark and fuel mapping, targeted fuel injectors and moved the o2 sensor, can someone please tell what the o2 sensor does and why it needed to be moved....and explain the rest of the changes. Can I upgrade my new 08 with all the 09 changes?

I am not positive but I think they moved the o2 sensor it to help it run better at a lower RPM and also give you better MPG. The O2 sensor helps with your fuel air mixture.

Magazines say that the injectors were 're-aimed' to prevent fuel pooling in the intake tract and the O2 sensors were moved to get more accurate readings.
