Way back in 85 , I built a xr185 engine into an 81 kx125 chassis. Once I realized it worked well , I bought a big bore piston 12.5 to 1 compression piston and a midrange aftermarket cam . Had a custom exhaust bent at a muffler shop and had an old cr480 muffler welded on the end . I rode single track mountain trails for about 6 years on that thing. It was awesome fun . Called it my KXR frankenbike.

Retired and too cold to fish here I Utah. Have enjoyed watching all your videos.

Great video and just what I was looking for. I just got a mint condition 2003 model. It was owned by one guy who was in his 80's He rarely drove it. Probably less than 1000 miles on it. Thanks for sharing this knowledge.

Great video bud 👍🏼

Great little clip dude! We bought a minty 2006 CRF230f. Love the easy wash and wear nature (compared with the 2012 CrRF250x that is fun but needy) but, yes, suspension is too soft with no adjustability. Oversight on Hondas part, along with the missing kick starter. Anyway, hoping to follow your leas on the suspension mods, and maybe open up the airbox. I love your style of video. Easy going but filled with hard facts and info. Cheers!

Your videos and commentary are spot on! I just bought a 2004 CR230F and starting to trick it out. I looked on eBay and other sites for the red anodized bolt and nut packs but couldn't find any. I was wondering if I bought a universal bolt and nut pack and took them to an anodizing shop. What do you guys think? Would that work? I can't imagine that would cost too much. If anyone has a better website let me know.

nice editing,great vid and keep it up

I put a Hagon shock on mine. Huge improvement. Also used a Race Tech valve in the forks.

Love love that bike

Great video love the way u put it together

I am 67 now and race vintage MX on a Bultaco mainly because I can not get on modern racebikes...its a too tall/too short thing. I did try a similar adventure back in 2017 with a Yamaha TTR 230 that ( I could not touch flat footed on) I modded...well tried to...to ride modern MX around my area. Figured it would give me more choices to race if I had both modern and vintage racers. The trouble is I was 62 then and had to ride the +50 class as that is the only old man class for modern tracks around me but I figured I would give it a shot. the first time I raced the Yamaha i got a bunch of crap when I pulled into the gate with a TTR instead of a YZF. I laughed along with everybody else until I told them how old I was they all stopped laughing immediately. IDK if they were amazed I was out there or just felt sorry for me or both. Anyway gate dropped, we all took off I managed to stay mid pack for a lap or 2 then slid out in the sand and was relegated to last place. Not much better the 2nd moto. The next race on the Yami was even worse as I fell and tweaked my shoulder the 2nd moto so that ended that day and my pursuit of riding MX on a bike I could not flat foot. I had no business being out there with those "young" 50 Y/O's. Sold the Yami and now I stick to my Bultaco with no suspension at least I can get on that and ride with guys my own age. The end........

That was a good video by the way.

Awesome!! I swapped CR125 forks onto my 230 a couple years ago and big improvement over the stock. Think I'm going to pop for some gold valves for that this summer. The CR forks high speed circuit is too stiff for Enduro riding in the rocks. Also did some weight reduction, but I'm spoiled by kick stands, so I tig'd up an aluminum stand. Thanks for the killer vid. Are you Eddie Van Halen's stunt double?

Great video! Thanks for posting it. Are you going to add a parts list buy chance?

Great video

Nice video! About the image at 6:43 it is right? Why so much difference between the rear wheel axle and swingarm bolt?

Awesome man! Fixing up an '08 230 now. What jetting did you go with and what weight fork oil??

Very cool video

Where can I find info about the tricked-out bike that you reference in ‘stills’ ? The shiny red/black one ….

14:36 I was guessing 15lbs. I'm just about set on a CRF250f as my next bike, trails, light enduro. My issue with weight is mostly about being able to pick the bike up, and pull it out of a ditch etc. I wish they/somebody made a 250f with about 30hp that came in around 200lbs wet/curb, not 265.

cool video cool bike ! what is the carburator on it ? did you change it ?

For the amount of work you have done to your CRF230 chassis/Suspension wouldn’t it be better to just engine swap the CRF motor into a more suitable chassis? How many dead CRF250/450 only a few years old are there with blown up engines. The XR200 is part of the same engine family as the CRF230, lots of engine swap information on swapping a XR200 engine into a race CRF250/450r. I’m planning this but using a DR200 engine

I love the concept, but it looks like red threw up all over it. It's actually better to give it some variations in the color in the smaller areas like hardware and smaller parts. It does not make them all show up as obvious changes from 50 feet away 🙄🙄🙄but in close where it matters they are obvious upgrades. A lot of that red anodizing would look better in silver and black. Anyway, if you like it that is what matters.

Where did you find that a 2021 CRF 250R weighs 204 lb? Honda says it's 237 lb wet, which is how you'd ride it. But if it were empty, that'd be 225 lb, which is a good weight for a 250 MX bike. And I dig the weight reduction project, but you didn't really answer why? If you wanted to moto, a used CRF250 can be found for less than $4k. do some maintenance the PO deferred, and you're way ahead in the capability of the machine. Clearly, you are capable of taking care of any bike, even ones with more frequent maint. requriements.

I took a full 10kg off my GN125, it's now at 100kg wet. Noticeable on a bike with no power for sure

Tom you said you drilled out your axles what does that do to the strength ?

8:25 At a glance you look like you could be Eddie Van Halen or his brother, sure look a hella lot more like him than his own brother lol.

Hey mate can you please tell me about the exhaust and what exhaust it is

00:47 You're not 'regulated' bro, you're relegated. *EDIT* : Yeah I hear that lol, I do the same thing. 25hp, should make it just about right I think, I'm just not wild about bikes with like14 to 17 hp, at over 200 lbs. My bike is 11hp, 140cc, 190lbs, I think I'd be happy with a bike under 240lbs, with 25 to 40hp, hence the CRF250F , a reintroduced model in 2019, that was called something else back in the day. I'm sure you're familiar with it; '19 through this year so far. I wish they would lighten it up a bit, then it would be perfect for what I want, I think it's 265lb wet. Thanks for the video.

Where’d you get all them red screws and bolts?

Where did you get that sprocket?

Dirtbikes yes....if u ever wanted a street bike ppl u can...still same frame and engine.... X22R .... Road legally allowed

Get a fcr carburetor

Crack 😂

This is a bit ridiculous. If you want a lighter bike then by a motocross bike. I’m was all for it with replacing steel part with aluminum parts, but you drilling out “everything” is insane and looks stupid. That is a trail bike, not a race bike. You did all that for 16 lbs! Im surprised you didn’t drill holes in the motor and drain a little oil out of it. That would get you a few more ounce.
