Honda CRF450R Off-Road Bike Build

We picked up this abused 2005 Honda CRF450R for $1000 off the local classified ads. With a price tag that low we were expecting some wear and tear but since the engine that wouldn't run, we didn't know the extent of the carnage until we started tearing into it. We knew a full rebuild was in order but after finding a transmission gear that was stuck and bugs inside the cases, it confirmed we had to go over every nut and bolt on this bike. So in this video we show off all the parts we put on our 2005 CRF450R to turn it from a roached out $1000 bike to a purpose-built desert racing machine.

What are some parts you have on your CRF450R that we should've included on this build?

[@lukerogers4368]

Seal savers

[@H8er-Maker]

Rekluse clutch but weighted basket w/hyd clutch was a good choice as well. Boyesson super cooler w/ ported water pump. Tokyo mods carb bowl w/ AP fix & pilot delete. That kick starter really makes the red accents "pop", not much of a powder coat fan cuz of it's durability but it turned out very nice. Well done.

[@salami373]

Bruce Simmons I live up in Canada, and was wondering how Tokyo mods is for price, quality and time wise? I’ve heard good reviews but am on the fence ?

[@NewGamer101]

i like this guy, he should be your main representative.

[@salami373]

Been slowly building a 02 450r Crf, all parts coming off the Rocky Mountain site! Great how to videos helped me replace top end and all valves ! Thanks !!

[@BigWurm10]

Good series, guys. Enjoyed watching it!

[@ashleydesrosiers7150]

I just bought an 07 crf450r, and I'm so glad I came across this video. This bike is sick.

[@fireboltaz]

I have the same one. Been stored for about a decade. Going through the fluids now. Got new plastics/graphics kit from Decal Works (Stars and Stripes theme). Looks great so far!

[@eduardomenchaca1916]

Y’all did everything right wow what a great job

[@elijahnelson7944]

You guys need to do a roach to racing series with a two stroke bike.✊

[@Steven-jq8jj]

he did a yz that was sick

[@jakepoe1247]

Thats a four stroke ronnie mac would be proud of.

[@carsonmiller9658]

That's a four stroke ronnie mac would piss on. Not even a motocross bike.

[@milestsinnijinnie8344]

You guys should put fast flex handle bars and yoshimura exhaust

[@ericc90]

We need a two stroke build next please!

[@aeror115]

Man what a Dream bike 🤙

[@josephpittala9146]

It would be a good thing to list out prices for all of us out here who dont have unlimited budgets. Food for thought.

[@Dr-kn5yh]

Joseph Pittala he literally made a list of exact parts and prices for everyone, read description next time. Also you average joe can afford this bike, all parts were under $2800

[@StilwellMotovlogger]

They just built this thing and can already seen where new expensive powercoating is wearing off

[@HybridEdits]

Can you guys please do a ktm 350sxf gncc conversion build? So many use sxf bikes as woods/trail bikes and im in the same boat on what all i should add to it to make it better.

[@hopeboxshowstoppers5513]

Much love from SLC Utah

[@joshvargas1038]

Helo from México! Can You make a vídeo of a BMW 450 Enduro? Dos You have after market pices for it?

[@AGShtareff]

Здравствуйте ! Классно то что вы сделали с этой хондой дали ей вторую жизнь , хотел спросить как вы реализовали охлаждение ? У меня тоже хонда crf 450 x8 стоит вентилятор но она всё равно греется !?

[@papoloco30001]

great job, tks from colombia

[@mitchbravo3068]

Do a old 300 smoker rebuild !

[@rmatvmc]

She is pretty dreamy :)

[@mattnelson8805]

Could you guy do vid on setting up on the suspension I have a 07 250r I would help a lot

[@rmatvmc]

watch this video and it should help you out. kzbin.info/www/bejne/n5qlfYSGnrediMU

[@shaun7126]

18 CRF250rx

[@hoosiertrailrider]

Nice overview.

[@codenamenoob4973]

"The 4 stroke revolution started with Yamaha" ever heard of Husaberg? 4 stroke force, started winning alot of races in the late 80s and stopped production in 2013 but by that time they where basically KTM

[@desert4seat]

Those late 80"s Bergs were definitely BAD ASS. In some cases, way more advanced than the early 90's YZ400's.. but I've never even seen one in person - super rare in the states.

[@lmtada]

Good point. I owned a 1995 Husaberg Fc600. Crazy power, hard to start, difficult to sell on resale market. Cool factor was big, until Yamaha yzf400 rolled along in 98.

[@drewkleinbach806]

TIL i was saying Acerbis wrong

[@MotoBuilds]

No head work/valve job? Or did I miss that?

[@Canthony_]

Sick💪💪

[@alexsoto7383]

What gas tank is that? I have a 07 450r I'm looking for one but there are so many options. I really like your gas tank.

[@rmatvmc]

That's the Acerbis 3.2 gallon tank. There is a link in the description with most of the parts we put on this bike!

[@GTK128]

How much was it for the build?

[@burntheprideflag2024]

5000$

[@aaronrmz2502]

Bike is completely "Tusk".. Should have titled the video "Tusk CRF450"

[@jacobtietjen8205]

That’s because tusk is based out of Rocky Mountains warehouse

[@Jsloth4130]

What mods were done to make the Acerbis skid plate work on the 450r? From what I can tell it is only supported on the 450x. Thanks for doing the videos.

[@illhaveanother4365]

Yes

[@tristanreed9331]

Oh my lord. That is my dream bike. I've been trying to same up for one but it's hard seeing how much they cost. I love riding my honda xl350 in Colorado. I can't jump it though, it doesn't have enough power or good enough suspension.

[@propacollector3499]

i wouldint call it goldin years the goldin years is cr 600 in a af frame

[@tylerberry2476]

How much did you spend on the entire build of this bike???

[@ArkansaDave1]

Probably closing in on the cost of a 2019 CRF450RX

[@johnstubbs1]

Always my question when someone does a full rebuild. Only reason to do something like this is if it is significantly cheaper than just buying a new bike...otherwise who cares if the 15 year old bike can now keep up if it is $2k more expensive than a new bike to get it there.

[@SeansLittleBayofHorrors]

If you can pony up the cash to buy a brand new bike go for it. Some people's budgets require they start with something old and slowly get it where they want as the budget allows. It boils down to whether you want to be riding or sitting at home saving pennies.

[@Toonces311]

I may add that many really enjoy building up a bike like this.

[@dominickjohnston5881]

What was the reasoning to not adding the dual pipes ? I’ve rode 450’s with single and dual ( both carb) and the dual pipe seemed to add more torque and over rev

[@rmatvmc]

This bike is a 2005 so before they came out with the dual exhausts for them. But the dual pipes look and sound sweet though!

[@oscarhorta8620]

Did you add a kickstand and if so what kind?

[@Instabum]

It came with the bike when they brought it

[@rmatvmc]

This is the Pro Moto Billet Kickstand on this bike. You can check it out here: www.rockymountainatvmc.com/parts/pro-moto-billet-kickstand-p

[@Bilkkis]

is this a 120 or 140 ? I'm talking about the rear tire ?

[@rmatvmc]

I believe it's a 110/100-18 rear tire on this bike.

[@dominatorgaming9989]

Hey the old rims and plastics that were on that Honda do you think you could send them to me

[@shishirkhadka5756]

Does that ACERBIS tank come to this crf bike???

[@mechanizedfuture1694]

With the 2005's is there an option to add an e start?

[@rangerclass7s]

The downfall was the shitty powdercoater that coated the bike... paints coming off everywhere. Besides that awesome build

[@scottporter4871]

Is a CRF450R a suitable bike to use as a road bike for weekend blasts a commuting from and to work?

[@brucebanner2039]

No.

[@DomMensche]

Anyone got a dirtbike for sale? Mine just straight up died. It was 20 years old. Kx65

[@scottiusnevious5143]

I wnna rebuild a clapped dirt bike.

[@wanted_450r]

Come over to my house

[@enduroislife1046]

Hi can you replie quickly where did you get the acerbis big tanks

[@rmatvmc]

www.rockymountainatvmc.com/parts/acerbis-fuel-tank-p here is the link to our page for this tank.

[@clutchmoto405]

What did you do about overheating in rocky or single track?

[@rmatvmc]

Ride faster ha ha. To be honest we didn't have any overheating issues after the rebuild. I guess we weren't riding gnarly enough terrain. As long as you have your jetting dialed, and your coolant flowing the bike should be ok. There are a number of different things that you can do to combat overheating but we didn't do anything special on this bike. - Wes

[@clutchmoto405]

@@rmatvmc awe ok, yeah mine runs around 150-200 on hard trails. But it may be that my jetting is off

[@mr.mathews6485]

What was the total cost to rebuild this bike???

[@illhaveanother4365]

Yes

[@randomtheater2159]

Can I have the bike plz?

does anyone make a plastic restyle kit for this bike?

[@burntheprideflag2024]

This bike is a 2005.

did you spray paint the frame lmao?

Hah! "..to keep them from going back to their old crooked ways..."

[@carterallen2889]

So many engine upgrades cause hondas been selling the same bike since they were released

[@tgr626]

Crazy Driven Honda has gone through several generations of CRF450R and has changed a lot over the years

[@enriqueaguayo4811]

Should not have powder coated. And all that bling stuff is horrid. Nothing more beautiful that a factory looking bike with brushed aluminum stock pieces

[@theborg269x]

6k later lol

[@rmatvmc]

Lol why buy a new bike when you can build one? 🔧 - Wes

[@StanleyKubick1]

Not a build, just a shopping list

[@user-oq9zd5rx3e]

or maybe you just buy a newer trail bike?

[@georgerankin989]

Electric Dirt Bikes

[@X_CHILLer_X]

Never run a plastic skidplate

[@ronntice7562]

FALSE ... the "four-stroke REVOLUTION" ... started with Husaberg.

[@lmtada]

I had old husberg 640. monster....hard to start. forget about finding parts. if you did find parts, it would cost you your first child, crazy. Husabergs are very difficult to sells, expect a year to sell. lastly knowbody even knows what a berg is, unless hardcore MX dude or a swede.
