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.Read All Reviews

Item arrived in Kansas within 3 days of ordering. Found the best price from Rockymountainatv even better than Ebay or anywhere else. Arrived as described and performs as expected. Ill keep ordering from here as long as things continue to go smooth. Almost forgot, the rocky cash or whatever is a bonus too. I just made my second order and used the 15 bucks i got on that purchase. came out to about a 7% discount.Read All Reviews
