    Huge improvement!
    I bought this to help out with the terrible bottom end torque of the injected yfz450s. With the air box lid off and the core out of the factory exhaust, it made it a different machine. Best money I've spent on a bolt on part!

    Woke up my Honda 700XX
    Why didn't I do this years ago, this thing is easy to install, great instructions that were specific to my bike but the print is a little small for my old eyes. They even have colored pictures using your exact bike. Easy to program and in each different program mode one can make quick adjustments in the field for any load or throttle position as needed depending on the mods that you have on your bike. Completely eliminated the idle to full throttle hesitation that all OEM 700XX's have, fuel economy went down but it was never good anyway, guess I need to get a desert tank for it next. Good product for a fair price with a 2 year manufacturer warranty. the only thing I was disappointed with was there was no sticker-yes no sticker.

    Simple Fuel Controller install
    For the price of any of the three button controllers you cant beat it. All of them are the same and offer the same style of tuning. Its simple to operate and installs in about an hour depending on you level of mechanics. Works great with full DASA exhaust and Fuel customs intake for the KFX. Will work on any year KFX 450r. A Great starter controller for the occasional racer or the avid trail rider.

    I have this same thing on my 2012 yfz450r and it got ruined but i can't find any that say they are compatable with a 2012.. Would this still work on a 2012?
    A shopper on Sep 29, 2016
    BEST ANSWER: We only have this listed to fit up to the 2011 model. If you had one on there before, maybe it works? But I can't guarantee the fitment to your 2012.
