Racer X Films: 2004 Kawasaki KX125 Garage Build

[@AustinLeeckRacing]

That guy is so well spoken, I love the bike

[@dirkharvey]

Ping! Dude, give us some feedback on these 'garage builds', is this one of the best 125's you ridden? How does it compare to the modern ktm/hus 125's?

[@Peanutdenver]

Is it asking too much to let Ping race this Kawi at the next 125 All Star race in Millville???

[@bikerdude6119]

I came here after I saw swapmoto 2020 Kawasaki 250 , This is much more relieving....

[@bubbasouthern5218]

Love the story & the Bike.. Amazing Job

[@robertrishel3685]

Just gorgeous! That thing BARKS!

[@user93634]

One day I am going to build something like this. I would love to do a Rodney Smith 2005 RM250 GNCC build with the RG3 A Kit suspension.

[@jeremiahlogan6202]

Looking at an old kx 125 just makes me think about break tapping.

[@jdatwood7086]

Damn! 38HP out of a 125 is amazing. Those late 90’s early 00’s bikes ranged from 32-34HP stock and with two strokes you gotta really work to make more power. Two strokes by design are already on the edge of making HP or blowing up. Very impressive build, I’d love to try it out.

At 7000 feet ! Bet it would break 40 at sea level.

[@db1988]

Kinda always amazed when guys talk about cutting subframe like it's some secret or big thing I've been doing this to many of my bikes since 2000 close friend and I discovered this and tested on our own it really helped me the sear hitting me in the butt in the whoops

[@mikebrown41182]

He never said it was something secret? It has never been, subframe cut equals balance in correlation to the suspension as you would know - and definitly worth it for people of shorter statue. But what Spencer was saying is that the stock Kawasaki 125 and the 250 two stroke from that era had a stinkbug effect, wich is well known. But lets be honest here the average joe might not know much about it.

[@claytonsmoothy314]

You are a genius!a legend! definitely the first to do that😂😂

[@TwistandShout257]

Holy shite Spence! 🤑 Looks like a damned blast to ride ✊🏼✊🏼✊🏼

[@mikebrown41182]

Steve Whitelock i still blame you and The AMA for the death of the two strokes!

My 04 kx125 didn’t sound like that !! Lol. Super nice bike 👌🏼👌🏼

[@mikebrown41182]

Stock in comparsion to factory is quite a bit different. This engine screamed!

[@kylemace]

Torosus Horneri I agree.

[@dirkharvey]

This is also a 144

[@curtishanna4960]

Did they do anything to the airbox? I know Stewart's 04 125 had the entire back of the airbox cut out with mesh wiring covering the hole.

[@KSH172]

How much are these bikes going for these days? I have a 2003 kx250 98% stock still has the original warning sticker on the back fender.

[@DGfilms1996]

KSH172 probably in all original shape 2500

[@appliedperformance773]

KSH172 2003 I not the latest generation for kx250s but if it’s truly low hour than 2500 all day. If it was 2005-2007 it would be slightly more valuable. Still would sell pretty easily.

$250 for 5 gallons HAHAHAHAHAHAHAHA

[@aaronmarzec2018]

takl23 Still cheaper than one gallon of Astroglide or one gallon of white-out.

[@epicbagelswag]

Why every 5 hours?

[@t-train6534]

epicbagelswag probably don’t care anymore but the guys that were really good and had factory sponsorships would replace a top end on the 125’s after every race. I imagine with him running this 125 at 38 hp (300+ plus hp per liter) he is probably losing a significant amount of power just do to compression loss. To keep it in tip top shape you need new rings or new piston that often.

[@dr187mx]

Big money

[@gwbruce8107]

[@grecoconduris6716]

Wow

[@GTFPOB]

Curious how it stacks up against a new 125 from ktm or husky

[@fullnoyz7670]

GTFPOB if a yz 125 can hole shot at the 125 all stars and win so with the right guy piloting it, I’m sure it can stay with them or beat them ?

[@pranramsamooj8187]

38hp at altitude, with the right rider it will do well..

[@jessebryant9233]

*James 'Bubba' Stewart* should come out of retirement... Ride for Pro-Circuit... And run a KX125... Just for fun! That would be a WIN for EVERYBODY! (Unless Stew's unable except the limitations of the machine and still tries to beat EVERYBODY... and ends up hurting himself.)

[@stephenwilson1012]

Have you watched his latest interviews? He hates racing. Said hes touched a bike like 3 times in 3 years

[@jessebryant9233]

@@stephenwilson1012 Yeah, to obsess over something for so long and then hate it... He's probably never had as much fun riding in a season as his brother does in a week. It's too bad. But actually riding 'just for fun' might allow him to rediscover why he started doing it in the first place! Hey, I was never a Bubba fan (huge respect though), but gotta love Mookie!

Yea 38hp is cool and all but for 30k Jesus, a bone stock ktm 125 2019 makes 39-40 hp

[@mikebrown41182]

Do you know why? Because KTM have no secrets, literally everything engine wise is a byproduct of the last years of factory racing. What KTM have stock engine wise is literally the same as Langston and Hughes raced back in 03-04 before the big switch. Kawi stoped at 04. But 38 HP for a old kawi with older technology is damn good. Sounds better than any KTM aswell.

[@mitchellsmith7162]

Torosus Horneri fair point but ktm sound pretty good too

[@johnbabb1138]

That hp was at 7000 feet , more like 46 hp at sea level

[@mikebrown41182]

@Taylor Anderson I am doubtful . I talked to Goose regarding rickys old 250 rm bike (05 supercross) 60 hp at the wheel with unobtanium parts. 125 twos trokes 44 hp at the rear wheel hmm. 40-42 maybe. But i can be wrong but it seems like a exaggeration

You can? If you want to spend the money. Definitly not lame, its a piece of art and one should hail someone that is a fan of the sport and a weekend warrior for building such a beautiful machine.
