    Must have, easy upgrade!

    Comments On Feb 25, 2016:The ECU is easy to install and it improved starting immediately.
    I haven't bought the programmer yet, but that functionality is also a great feature.

    It starts easily and runs much better now.

    Comments On Feb 03, 2016:This is a must have for the new Yamaha WR450F's. Starts much better and runs much stronger even with the factory tune it comes with out of the box and less stall prone. But to fully take advantage of this ECU you need to purchase the GYTR programmer as well to change the tune of the motor. I've been running the tune that came with the ECU and have been very pleased and have not yet purchased the programmer and not sure I will.

    Comments On Jun 25, 2014:Should be the first mod you do! Install takes 2 minutes and with a tuner will unleash the power this bike should have. Throttle screw can be slightly tricky, but it's more than worth it. As always, RM has super quick shipping and great prices.

    Everything you need to uncork your WR450f

    Comments On Mar 06, 2013:This kit is great, comes with new CDI box, and repalcement throttle stop screw. Just use vise grips to remove the OEM throttle stop, it has a special head to the screw. Once you start removing it you will understand why it must go, its nearly 4 inches long and the replacement one is under an inch. This kit is the single best thing you can do to your WR450f. Oh yea when you''re done installing, drill out that exhaust baffel or even better get the FMF wont regret it.
