When Mutch Payton gave us the engine that Dean Wilson used at the start of the 2017 Supercross — the engine that got him a Husqvarna factory ride in four races — we decided to build a Dean Wilson Replica YZ450F. Take a journey with us as we track down all the parts, including works Kayaba Suspension, to build a true-to-life replica that anyone can build (with enough money).
The MXA wrecking crew irons out the wrinkles in the 2017 Yamaha YZ450F. We give you 14 pages worth of tech tips, pratical advice, proven solutions and multiple maps to make your YZ450F perfect for you.
You may be the macho four-stroke pilot at your local track on your CRF450, YZ450F, KTM 450SXF, KX450F or RM-Z450, but how would you do on the 1976 Yamaha TT500? This was the best Yamaha four-stroke made at the time…it was also the only Yamaha four-stroke motocross bikes made at the time. It may look crude, but riders won on these beasts.
Jamie Ellis from Twisted Developmet is the master of black box magic. His Husvarna FC450 engine makes 65 horsepower on the start, but two laps late rit mellow out into an easier to ride lap-time engine. How does he do it? Electronic wizardry.

Do you subscribe to MXA? You should. We know that you think that print magazines are dead and that the internet will fill the void, but most of the stuff in the current issue of MXA won’t appear on the web for several months, if at all. Luckily, you can get all of MXA on your iPhone, iPad, Kindle or Android by going to the Apple Store, Amazon or Google Play. Better yet get the Digital desktop version at https://hi-torque.com/product/motocross-action-digital-edition/ for $9.99 a year.
The MXA test riders prefer the print version and not just because it is delivered by a uniformed employee of the U.S. Government, but because right now you can get 12 issues for $19.99 and a free $25 Gift Card from Rocky Mountain ATV/MC. That means that there is a profit to be made in this deal for you. For the Print magazine go to: https://hi-torque.com/product/motocross-action/
