2020 Yamaha YZ250FX Bike Build

[@jondoecan]

I have the 19 Yz250fx. Best dirt bike I’ve ever owned. I’ve done the fan upgrade, and brush guards. Snapped pics from the video for more ideas.

[@fosterkatchen7010]

This bike is awesome!

[@bubaa1218]

They should rebuild the 450 that Chase Road in the 5 miles of hell and go through it all and maybe the motor even though they just went through it it did get a Little hot lol

[@ronniewilliz153]

Tusk makes some great products. Killer build man.

[@nepicness]

That’s strange, I’ve hard one on my 2013 300 and it’s been rock solid since I got it

[@tenderblender945]

Phil Ward with rad caps and thermostats it’s weird, on any male or model with any brand of part, it seems like the failure rate is about 50%+, I check new ones to make sure they work or I return them immediately for an exchange. It’s crazy that it’s like that, but that’s what I’ve noticed.

[@gerigtuning]

Why not run the gytr radiator fan. It's probably cheaper than the tusk. And has proper mounts on the radiator and has a plug directly into the wiring harness for it!?

[@thealvaco]

If I drank a shot of whiskey every time I heared tusk...I'd be dead now.

[@russg9787]

Yup, it was quite the sales pitch.

[@skyusable]

I kind of wish they wouldn't promote their private label brand as much. But then again, higher profit margins allow them to justify making videos. I used some Tusk stuff, it's not bad and at a good price point.

[@nepicness]

He could’ve not had the company support and just a discount where price still mattered. They do make the best priced stuff that still works great. It can cut the cost of some of these upgrades in half.

[@tomcat6933]

Do you get a commission off the after market parts you are advertising

[@rmatvmc]

Nothing wrong with quality parts at a good price. We are riders building product for fellow riders. The products added to our builds are all by choice (Tusk or not). If we can offer good products at a lower price, why wouldn't we want to let you know about it? And yes, probably not a good idea to turn that into a drinking game lol. Thanks for watching - Wes

[@63keim]

Gytr has a radiator fan that plugs directly into the existing harness, you installed a tusk hour meter when... The app has that. Your stalling issue? There is a TSB for a computer reflash, that yamaha covers to fix that hard hot restart. Look up "yamaha yz 4t tuners" on face book for maps.

[@Sssextreme]

Thank you for info about battery, I have same problem. I will try change battery

[@olliechristopher467]

Thank you TJ for showing your bike build. I have noticed that the Tusk brand has really taken off the last few years with really great quality parts at a good price point. The hoses are really nice. FWIW, I put Flex Bars, ASV levers, and Fasst foot pegs on all my dirt bikes. Good job and the bike looks really nice!!

[@Jussi567]

Good looking bike and great upgrades. Good to hear about those Fastflex handlebars, I have had the same issues after wrist injury

[@mcsbikelife3829]

Jussi #567 get the major mounts I’ve broken a few sets of those fasst bars. You won’t break mako stuff and it’s better feel.

[@chrisw7642]

Mc's Bike life The Mako mount is $400. For a bar mount with a polymer inner sleeve. Insane.

[@Ignocx]

Beautiful bike it's so cool I have a 05 yzf250 big bore but I love it great riding man

[@JN-ge2uh]

Great. Now I really want one. Great video guys

[@cynthiabowers2960]

RMC is my go to place for parts. I love their how to videos, and especially loved their 5 miles of hell series, awesome. However, many of us out here have 15+ year old bikes and use RMC to keep them running so we can keep riding. Furthermore, with presently 17 million people out of work I think it is rather decedent to buy a new bike and then spend $2500 more to "upgrade it". Just my 2 cents worth.

[@Madtigertv]

Might wanna put that 2 cents in the piggy bank and save up for a new bike Karen

[@joe0813]

I just bought this same bike. I have noticed it doesn't like to start after you stall it. Any Info on that research you did? So far all the research ive done on this issue is not the battery. Its the idle CO gas

[@jeffc.5597]

Asb levers are the best!

[@SoSlo2]

Very surprised radiator braces weren't at the top of the list for protection. One of the first upgrades I did on my 250fx as the radiator mounts are well known to be about as strong as an empty coke can. Otherwise, love the build. Congrats on an excellent bike!

[@rmatvmc]

The Bullet Proof Designs radiator guard is super tough and protects the radiators very well. Which one did you go with on yours?

[@SoSlo2]

@@rmatvmc BPD makes some great products. No doubt about that. I have the Devol braces + guards on my '15. The braces tie back to the frame to add additional rigidity. When I first purchased my bike, it didn't have the braces and one of the radiators was bent in at the inside mounts. I was able to bend it back and the braces have kept it there. Braces are usually the first recommended mod in most of the 250fx groups and forums as the weak mounts are well know for bending relatively easily.

[@terryarthurs548]

Thought about a hydraulic clutch kit?

[@michaelwalas5948]

Just a word of advice for you since you mentioned you had thumb surgery. I would lift you levers until they are nearly level. I noticed your levers are pointing quite low.. what that does is put so much strain on your thumbs, especially under heavy braking … you’ll also feel every bump and it’s very dangerous for big jump landings.. in some countries that made it a law to level out the levers in super cross to avoid thumb injuries and also horrific wrist injuries 👍🏼 Try it .. you’ll get used to it and you won’t need that absorbing handlebar either 😎

[@mt1885]

Will you do a Bike Build on the *KTM 250 XC-F or 350 XCF-W* don't like the Aluminum frame and the YZ is TOP heavy/WIDE and small gas tank - plus a tank.

[@rmatvmc]

We have a couple older build videos with a 2016 350 XC-F and one on a 2015 250 XCF-W. If you're interested in those, there will be links to both videos below. 2015 KTM 250 XCF-W - kzbin.info/www/bejne/kGeoYYOJlttmopI 2016 KTM 350 XC-F - kzbin.info/www/bejne/bWGuq5ajZZWUrKc

[@nepicness]

Glad the suspension wasn’t sent off and factory A kit stuff put in and a full race engine! Regular guy build with some practical upgrades. I probably would’ve done the levers, wrap around handguards, skid plate, shark fin, and maybe Lexi exhaust

[@chasp_0784]

If you want an arrestor and not a new can, check out Fisch spark arrestors, screw in, fit in 5 minutes. Mint

[@reeceduckworth1130]

I have the 450 fx it’s soo good

[@Groots22]

Amazing ad! Keep selling tusk!!!

[@SWTrailsAndWheels]

A weak stock battery is the source of starting problems? Seems odd that Yamaha would not get this part of the spec right.

[@trailrider383]

Did you mention the front brake disc guard?

[@gsnyder1550]

I love the bike i just recently bought a 2017 yz250fx and put 4 hours on it since i bought it and the motor locked up so I haven't been able to fully enjoy it yett..

[@rmatvmc]

It locked up with 4 hours on it?!?! What the heck?

[@gsnyder1550]

@@rmatvmc no I bought the bike used. i bought it with 20 hours and I have only put 4 hours on it since I bought it. so it has just under 25 hours on the bike total and its locked up. Vary frequent oil changes with Yamaha lube and fresh oil filters It was fun for the little time I rode it. Just don't have the thousands to have a shop rebuild the motor. And their is not step by step KZbin video yet...

[@jw1717]

Hello, how much does the bike weigh after the build?

[@darsol630]

This is dreams🤤

[@Accidentlpro]

It’s funny now that I own a ‘17 250FX, I’m wondering why you guys went with the Tusk fan over the GYTR? If you guys went with the front rad guards then figment shouldn’t be an issue

[@rmatvmc]

That's a good point. The GYTR fan would have been a great choice as well, but the Tusk fan allows for more temperature adjustability, a larger shroud for better cooling and of course it is our brand, so we wanted to spread the word about how our universal fan will fit on just about any bike that has a battery. Thanks for watching! - TJ

[@edharrison1108]

So want that bike😍

[@motodad1119]

I liked seeing a "trail" bike get some love. Not much else to do to an FX to make perform better. Basically shave weight (makes me question the Flex bars bc of this) and add protection. Maybe upgrade shrouds too, to help you squeeze with your knees. Other than that, this guy covered most everything. Hard to improve near perfection!!

[@tommytrzcinski8209]

How much does the bike weigh after all the parts you put on it? Did you shed some weight or add weight?

[@alexpanella6685]

So that’s where the last dirt tricks sprocket went 🤔

[@rmatvmc]

[@lmankj]

Nice mods, thanks

[@TubolMotoadventures]

Does it smoke on cold start?

How good is that gold x ring chain? Anyone know ?

[@westwing23]

is it possible to swap the 250fx motor/trans for my 2019 450F?

[@kiwi-moto]

showing more riding footage would have been nice..

[@rmatvmc]

We'll try to do better and show more riding footage next time. Thanks for watching the video and letting us know what you think!

[@tonycerruto5157]

This was a great video. Is there any reason that most, if not all the parts reviewed wouldn’t work on a WR250F? I have my sights set on the WRF but the more I see the YZF the more I question my decision.

[@Engrave.Danger]

Get the FX. The WR lights plug right in.

[@nickchristofora3417]

Did you find those levers making it an easier clutch pull?

[@rmatvmc]

The clutch pull was already really good on this bike, so I don't know that I noticed it get easier, but the feel, quality, and functionality of these levers are of course much better than stock. - TJ

[@DillweedMcCoy]

TJ, do you have any personal mapping that you prefer for trails and MX tracks? Thanks.

[@rmatvmc]

Hey Paul, the 2 maps that I have used the most are the MX power feeling map and Keefer's smooth linear (slippy) map. I use the smooth linear map most of the time I'm riding single track, especially technical rocky trails and also when the moto track gets a little too much water and is slippery. I use the MX power feeling map pretty much everywhere else (moto tracks, turn tracks, hill climbs and sand). - TJ

[@mikeyjack74]

Does that fmf slide on to the stock header? I have a 19 wr250f that id like to add one too.

[@rmatvmc]

Yes, we left the stock header and just went with the 4.1 silencer. We have this FMF silencer for your bike. Check it out on our website (Part# 1479360001). - TJ

[@mikeyjack74]

@@rmatvmc thank you. I will look into it. Just ordered the performance ecu from you guys. Along with two foot brake levers by accident.

[@DJMEDIC671]

Does that fan fit the F model also?

[@rmatvmc]

The Tusk universal fan kit works with just about any bike that has a 12 volt battery and room behind one of the radiators. Check out the instructions on the product page. - TJ

[@CampbeIIs]

Drinking game everytime you hear tusk drink

[@NEtrailrider1]

Nice build, no skid plate? or you don't feel you need one, just curious .

[@mxs8102]

[@rmatvmc]

Yeah, we felt that the stock one was really quite good, and didn't feel it was necessary to throw one on it. - TJ

[@chrisw7642]

Which bend did you go with for the Fasst Flexx? Thinking about getting one for my 2018 WR250F.

[@abusa0o0]

Very nice bike build. Assuming the bike probably gained 10+ lbs though.

[@lihxc]

How do you guys find this bike on the MX track? Looking to maybe pick up a 250FX but riding a combo of a lot of tight single track along with MX tracks but afraid it might be a little soft.

[@rmatvmc]

Here in Utah the tracks are barely starting to open up for the season, but I am really excited to get it out on a track. I will keep you posted. - TJ

[@nathanlancuba8182]

You might as well call it a tusk yz250fx

[@premixpeter1972]

Sweet build! YZ250X owner here, hope to ride one of these back to back with my bike to see how the Yamaha 2 and 4 stroke 250's compare as they compete in the same classes for off-road.

[@rmatvmc]

The 250X is a sweet bike! That would be a fun comparison.

[@RelentlessCo]

I have a 2020 YZ250X , the 250FX just feels dead and made me lazy . Much less exciting then 250

[@premixpeter1972]

@@RelentlessCo Interesting, I do feel that I can ride lazier on 4 strokes but also can ride them longer without fatiguing. What year of fx was it?

[@RelentlessCo]

Premix Peter it was 2020 as well. Riding the 250x doesn’t tire me out at all , can be in the tough stuff or ringing it out . Definitely brings more of a smile to my face then the fx , I do envy the e start but only when I’m on the side of some steep stuff or scenario similar.

[@premixpeter1972]

@@RelentlessCo Gotcha. For me it really depends on the terrain, generally the tighter/more technical/more vertically adverse it is the more I like a 2 stroke and the more open/flat/high speed it it is the more I like the 4 stroke.

What maps are you using and do you know where to find any more maps online?

Maybe should have just started with the WR for the fan and spark arrest....and a headlight for really dark woods enduro too. Either way, I'm in love with Yamaha these days. They are RAPIDLY becoming the dirt bike company of this century. I feel like nobody is throwing down the hammer every model year like them .... Is it me or are some of the other companies just like "buy us because we're BNG in red/green/orange" or whatever...?

Did you have to re map it when you got it? Mine was running really rich. Mapped it for a little more torque. I have ridden 450's for the last 13 years and this bike is a blast to ride. It revs so much higher and feels considerably lighter.

[@rmatvmc]

I have been running the "MX power feeling" map, and Keefer's "smooth linear (slippy)" map. I agree, this bike is so much fun to ride! I am honestly faster on it than I was on my 450 and it feels so much lighter and agile. Just typing this makes me want to go riding. - TJ
