Great bang for the buck
The installation took a few hours, but other than space being a litle snug in the bike, it was relatively straightforward even for a novice like me. The only con is that I dont like the vampire clip that is used to splice into the wiring. I may redo that with a better splice.

The bike (Honda 919) now delivers power more smoothly and responsively. It also lays the groundwork for slip on exhaust this winter.

There is excellent support from both the manufacturer and various bike forums.

Hi I intend on buying a Power commander for my bike (Hornet 900) in New Zealand. As I am buying a US spec PC3 I have read that some of theses specs are different and they cannot be tuned for RPMs less than 5000.?
Can I please have the part number?

BEST ANSWER: I'm not sure if they still do, but they used to make 2 versions on this, one was street legal and would not allow u to tune the lower rpms and the other was intended for race bikes only and allows u to tune the entire spectrum. I believe this is the same one i bought for my sv650s 2003 and this is the racing model which allows u to tune everything. The street legal version is the powercomander ex (i have no idea why anyone would actually buy it).
