    YZ450F‑INSPIRED. CROSS‑COUNTRY WIRED. Designed for closed course X‑Country racing, combines light, nimble handling with the power of a 450. Top Features Innovative Hare Scramble/GNCC® Engine Design The YZ450FX™ shares the revolutionary rearward-slanted-cylinder design of the YZ450F™ that allows for a straight downdraft intake with a symmetrical port layout. In the YZ450FX, this engine delivers a controllable, torquey power character with strong top-end power tuned specifically for cross-country racing. Bilateral Beam Aluminum Frame A nearly identical bilateral beam frame that is found on the championship winning YZ450F is used on the YZ450FX. It places the engine, fuel tank and exhaust close to the center mass of the bike for extremely light and nimble handling character. Advanced Fuel Injection The YZ450F-based Keihin® 44mm throttle body fuel injection system is tuned for cross-country racing and ensures smooth throttle response and easy starting in nearly all conditions. Cross Country-Specific Suspension Industry-leading, YZ450F-derived KYB® spring-type forks with speed sensitive damping and a linkage-type, KYB® rear shock both feature fully adjustable settings designed specifically for cross country racing. Cross Country Podium Ready With a two gallon fuel tank, sealed O-ring chain, and an 18-inch rear wheel with XC racing tires, the YZ450FX is ready to win right out of the box. Electric Starter System The YZ450FX features an electric starter to help reduce rider fatigue along with a main switch-free electrical system for easier starting off. Engine Cross Country-Tuned YZ450F Power YZ450F-style 449cc liquid-cooled DOHC four-stroke, with forward-positioned straight intake, delivers massive power specifically tuned for cross country racing, to challenge for race victories in the very competitive GNCC® and Hare Scrambles race series. Innovative Engine Design The position of the engine moves the rotational mass of the cams towards the center of the bike which allows for a straight shot, down-draft intake and straight exhaust port for ultimate performance. This also keeps the airbox up high, out of dust and mud/water. Wraparound Rear Positioned Exhaust Layout Lightweight YZ450F-spec exhaust system maximizes engine power while centralizing mass, thanks to the innovative wrap-around header design. Advanced Fuel Injection The fuel injection system uses 3D mapped electronic control for the fuel and ignition timing that are optimized for cross-country racing, with a YZ450F-based 44mm throttle body. Wide Ratio Gearing A five-speed wide-ratio transmission is used to insure the right gear is selected for a wide variety of terrain found in cross country racing, from tight single tracks to wide-open desert blasts. FX-Specific Clutch System Based on the YZ450F, the clutch plate material, springs, push lever and oil valve are optimized for cross-country racing. YZ-F-Derived Cooling System Large-capacity YZ450F radiators provide maximum cooling efficiency with great strength, and can be fitted with an accessory cooling fan for additional airflow at slower speeds. Electric Starter System Push-button electric start makes starting the YZ450FX easy and convenient, complete with a simplified electrical system. Chassis/Suspension Bilateral Beam Aluminum Frame YZ450F-based frame offers a compact size while optimizing mass centralization. With its extensively tested assembly of aluminum forgings and extrusions complete with model-specific engine mounting, the FX frame retains legendary Yamaha handling and response. Advanced YZ450F Front Fork Fully adjustable YZ450F-based KYB® spring-type fork with speed sensitive damping delivers precise, fade-free handling. Cross Country Shock The rear linkage and KYB® shock provides 11.6 inches of travel with adjusters for high- and low-speed compression damping, rebound and spring preload—and features a large piggyback reservoir for excellent damping and fade resistance. 270mm Front Brake 270mm front brake system provides exceptional stopping power and braking control. GNCC®-Specific Tires and Wheels Lightweight 21-inch front and 18-inch rear rims provide exceptional durability with enduro-specific tires. Additional Features GYTR® Power Tuner Ready Accessory GYTR Power Tuner lets owners adjust air/fuel mixture and ignition timing maps to match engine performance characteristics to the rider and race conditions in a matter of seconds with the push of a few buttons. Real World Tough Features Rugged plastic skid plate, quick-adjust clutch, aluminum handlebars and a side stand are standard for added rider convenience. Thanks to a WR-style fuel level sensor in the tank, the YZ450FX includes convenient fuel level and engine warning indicators on the handlebar. Simplified Servicing Redesigned air cleaner cover provides tool-less access to the air filter, positioned at the front of the bike to avoid roost from the rear wheel. A high-quality sealed O-ring chain is tough and durable. Embedded Graphics Yamaha’s unique embedded graphics are built into the bodywork for extended durability, resisting both peeling and damage.

    Hella fun
  4. I recently bought a Yamaha 2017 YZ450FX and the plastics are pretty beat up, so I have to get new ones. I came across a set of the 2016 60th anniversary yellow plastics for the YZ450F. For the most part will these plastics fit on the FX they look bad ass. I want them, but cant find anything stating if they will fit?? Thank you
  5. I'm new to the forums and I've been trying to read the few but super long 250x forums on here, and have been having a hard time sifting through off topic debates and mostly trail based reviews, which I was happy to see were very good. I want a new bike as I'm done with using a motocross bike offroad and need opinions on how the yz250x compares to a 450's ability to go fast in wide open desert and go up steep, deep sand hills? (I live in SoCal and ride almost everywhere but Superstition Mountain is my favorite place to ride). In a drag race how would the 250x do compared to a 450? I know it wont be nearly the same, but I'd like to know how far off it will be, and just dont have anything else to compare to. I want to make the switch because I miss the fun braaaapp of the yz125 i learned to ride on and feel I will have more fun desert racing in the 250 division. However... i love my 450 and need to be persuaded not to get a yz450fx which rn am feeling would be the safer choice because I'm scared the 250fx will feel too slow and untorquey by comparison. I realize the 2 stroke vs 4 stroke debate is basically unanswerable and in a perfect world imo everyone should have both. But, I need comparisons to 450s because I am 18 and in my 7 years of riding experience almost all of it has been on my 2012 yz450f, the only bike I've owned. I've ridden many other bikes for short periods but never a 250 2 stroke (a lot of the good reviews were based off these). thanks in advance for any help

    Best bike I've owned so far. The map switch makes it into multiple bikes with the push of a button. I bought it because I was tired of always chasing power with my 250F. Now I have more power than I will ever need and can focus on detuning it with the push of a button for tight single track. Suspension: best stock suspension I've ridden, this is the first bike that I'm not going to revalve. Works on single track rocks and roots while also getting me around a vet MX track. Handling: feels lighter than my old 250F and has much better front wheel feel/feedback. You actually get some warning before the front washes out. I'm currently running a 2 link longer chain, I like the way the bike handles with the longer wheelbase. Still turns well and is super stable on whooped out desert runs. Brakes: the front brake needed bleeding when new, but after getting all the air out it's plenty strong with good modulation/feedback. The rear brake works without being too grabby. Controls: the clutch pull is light and stays consistent, I do think the engagement point is abrupt, but I got used to it. The throttle cam is on the aggressive side at low throttle openings and will bite you if you get careless. Rider triangle: I'm short, 5'7", so the low seat and stock handlebar position works great for me. Contrary to other reviews, I don't feel like the bike is any wider than other liquid cooled bikes I've ridden. Plastic: the oem blue plastic has gotten much better than my old WR. After a year of riding there are no white streaks anywhere on the bike. The inlayed graphics are sweet, still look brand new! Overall fit and finish: bike is wearing very well. I'm still running stock Controls and haven't had anything break. My fork seals did start seeping at 18 hours, but after cleaning the seals and started lubricating the lower tubes after every wash they have sealed back up. After 13 months all I've had to buy is oil, tires, front sprocket, and chain.
  7. I have a 16' 450FX and really like the bike. I've been playing with the clickers and sag the past several months and have it feeling really good on faster trails although it's not very good on the slow 2nd gear technical stuff. The front end deflects really bad and the rear end deflects to the side and even straight up but not as bad as the front. I'm 6'3" 255 lbs .52 front and 6.3 rear springs. Sag is 110/34 and 330ml fork oil. Front - 8R 12C Rear - 6R 14LS 1.75HS Looking for some tips on sorting out the suspension to be more compliant on the slower stuff. I really don't want to send off to revalue unless I have too. Thanks in Advance! Jordan

    First bike I've ever bought brand new. Loved it since day one, put 80 hours on it in two seasons. I didn't add and aftermarket parts other than some brake guards and cycra hand guards.

    So I finally decided to buy a dirt bike after years of want and desire. I’ve ridden maybe 4 times in my life before I decided to make this purchase. I contimplated long and hard about how stupid buying a 450 as my first dirt bike could be but many factors came into play. For starters I’m a bigger guy (6’4 205lbs) so I knew I needed something to suit my size I also didn’t want to make a big investment with something I would out grow (skill/power wise). More importantly the main concerns I had were if getting this powerful of a bike was too dangerous especially considering I’m a beginner rider and my job involves everything physically demanding you can imagine. All in all I’m very pleased with my decision. How you ride is completely up to you the power is there when I want and I get off of it when I don’t. I’m very calculated in my decisions while riding which has kept me in good health. As far as the bike goes it’s awesome. First thing I noticed was the power (obviously considering I’m a beginner) but even compared to my buddies 450s and 250 2 strokes. Power is there at almost any gear any rpm. My favorite feature of the bike is easily the suspension. The KYB SSS forks are as plush as it gets. So is the rear shock. The FX features also suit my riding needs perfectly with a super meaty 18” rear tire, wide ratio transmission (only changes 4th and 5th gear) and plusher suspension. The one con I do have of this bike is the weight, all 262lbs of it to be exact. It makes tight single track a workout and steep down hill a little sketchy to say the least. All in all I’m very happy with the bike. I only have 15 hours on it in the 2 months I’ve owned it so I have much more review to do but I’m happy to say I can easily recommend this bike to anyone looking for a big powerful trail bike. Thanks for making it to the end I hope this helped!

    I love it so far, the tranny is awesome for offroad and the Rekluse makes everything easier!The "hit" off the bottom is abrupt and is a handful in tight single track. This can be taken away through re-mapping or a after market exhaust.

    My bike is actually a 2016 WR450 but that wasnt listed as an option for me to select. The 2016 WR450 is a great bike and has tons of power. I have the 450FX ECU and tune the power with the yamaha handheld tuner gadget. Its surprising how much of a difference the different tunes make when riding and I find myself using it a lot more than expected. The yamaha has been boringly reliable as someone that enjoys wrenching this thing requires nearly no maintenance and when it does its pretty easy to do. I've checked the valves lash 3 times and they havent ever changed from new staying right in the middle of the spec. My chief complaint with the WR is the weight. I recently was able to get a 2017 Beta 300RR and am going to try that out during 2018 riding season then decide which bike I want to keep. My hope is the Beta will be better in the technical stuff and give me some confidence to try new things.

    I just got the bike but just riding it on the street and cruzing around the block this bike is sooo smooth and it just amazing! I'm almost speechless! Every old bike iv ever bought and had to put thousands of dollars into it to make it remotely close to this bike out of the box bone stock!

    6'0'' 202lbs Novice\inter C-class rider<br /><br />Power from the bike is very usable, easy to control and manage. but there's a lot of it when you twist it. won't snap on you like the MX model though.<br /><br />Suspension out of the box is plush, especially the forks. the shock is fine for my stats, but the forks are a bit too soft for me. Before my revalve I just added 5cc of fork oil and that solved my bottoming issue on jumps. <br /><br />weight-wise this bike is a bit of a bear, but the power and suspension makes it seem more agile that it probably should be. I would quickly shave lbs with a lithium Batt, exhaust, and lighter tires with tubeless.<br /><br />Clutch work is easy, doesn't want to stall ever and the pull won't kill you in a 2 hour HS.<br /><br />Overall I think this bike is amazing once setup for you size and style of riding.

    2017 model Great offroad manners. Great suspension, neutral handling
  23. First post on here. I bought a 2020 YZ450FX I absolutely love everything about the bike except the gearing sometimes. I ride a ton of different terrain but I mostly ride with people who have 450f or similar bikes so we never end up in anything more technical then they can ride. I definitely have an edge in the woods but it’s not worth it too me because on the track 1st gear as people have mentioned is way too low. It also makes it difficult to work together on speed for jumps they’ll tell me oh I’m hitting it in 2nd wide open and for me I’ll have to be in like 3rd 1/4 to get the same result ect. Is there a good solution in changing the sprocket at all? Should I go up and use second as first or down and how many? Mostly would just like 2nd and 3rd gear to match up better with the Race model
  24. This video is part 2 of the ride I had last Sunday 1-12-20 . Out of all bikes I've owned in my time this Yamaha 450FX is my favorite .
  25. I just bought a Dr. D full exhaust for my bike and I've been looking around to try and find some mapping tips after I install the kit. I have the tuner. I've never mapped before but don't feel like spending the extra money to have the shop do it for me because the shops around me charge an arm and a leg. Any tips or advice? I live at 5000ft above sea level and I don't ride tracks as of right now.
