Two-Stroke Revival: Yamaha YZ325 Project Build

We had the opportunity to test ride a 2006 Yamaha YZ325 monster machine two-stroke. TJ Boyle presented to us his #twostroke project build that we can guarantee is a head-turner. Boyle made his way down from Arizona and met us at Lake Elsinore Motorsports Park where we could put this build to the test. Click play to find out what exactly went into this project bike and hear that crisp two-stroke scream.

This is what they should be racing instead if 450 supercross bikes! Omg that hand built works pipe is all out sexy!

[@tomatoknuckles]

That's without doubt the best looking yz I've ever seen. Absolutely love it 👌

[@jinoziniosti5633]

you obviously never seen a YZM500

[@dominocweber9763]

Yup🤤

[@kylereece575]

It's definitely up there

[@russellhelms2835]

A really really beautiful MX bike👌

[@scottfairbrother]

One of the absolute most beautiful bikes I have ever seen. WOW. Worth every penny.

[@croaker4163]

I like this guy, reminds me of my brother. Hey bro I'm just looking for a cheap yz... then proceeds to throw the entire bike away and builds it into a factory race bike 🤣😂👌 solid gold!

[@russellhelms2835]

Guy has some serious skills AND a taste for fine details. Absolutely stunning👌

[@erichildreth7562]

It is amazing as to how ceracotings can really change the look of a bike and you did an excellent job with this!! Sounds great too!

[@Kawiboy]

What a sweet bike. Well done TJ 😉👍 👊.. Thnx PING

[@russellhelms2835]

Agreed! Stunning fantastic💪🔥a real piece of MX artwork! and 💯functional as well👌

[@moto2103]

Just can’t beat that sound. Got me stoked to take my YZ to Elsinore this weekend!

[@MXKID34]

I'd love to ride this amazing bike, looks awesome and according to Ping rides awesome. Great job TJ

WoW!!!!!!!! great freaking job on on the shuttle color differences it flows absolutely perfect!!!!

[@APH.95]

The best yz build i ever seen

[@wayno23]

Beautiful build 👌well done.

[@cbh148]

Absolute kickass bike. I've got an '05 YZ125 and I wouldn't be surprised if I end up also getting a YZ250 at some point, and this is the pinnacle dream configuration for one to have. Didn't know about that RTech plastic kit. I have the UFO restyle kit on mine, which I like, but since it still uses the stock tank which has graphics on it, the white accents on my tank graphics have turned yellow. Ditching the stock tank would be a treat.

[@leift70]

That bike is SAVAGE!!!!

Awesome stuff T.J.! Congrats man! I would get very little sleep after finishing a bike that turned out so incredibly well. I'd be in the garage getting "would you please come to bed" texts from my girlfriend until 3 or 4am every night.

[@moparone7962]

That's a damn nice yz. Thanks for the info about the vortex ignition with a 325 kit cause I'm about to order one.

Awesome build! Im proud to say that I was at Elsinore for opening weekend loooong ago, and also looped my bike out on the first lap, tearing off the rear fender 😅😂

[@drewmurray6480]

You have built a work of art and if it was mine i would be scared to ride it and scratch it but that's what they are made for

Spectacular build! Tried sourcing 325 kits here in Australia but a lot harder than I thought.. Love the content cheers

What a machine pick this over 4stroke any day . Smiling under the helmet even wen ya having a bad ride braaaap

[@drewmurray6480]

What a top bloke for letting you ride it i gotta take my hat off to him and like you said i wouldn't want to get it dirty, i have done something similar with my 99 model cr125 but haven't gone as far as titanium bolt's and it's nearly finished and im so scared to get it dirty or scratch my sm pro platinum rim's with the talon hubs ,it sounds like me and him had something similar happen, i brought the bike and apparently it had just had this and that done to it and won't have to fix a thing well that was all bullshit and everything i touched or looked at needed fixing or replacing so the nut and bolt restoration began but atleast i have a basically brand new bike even though it's 20 something years old it looks like a sexy bit of a bike

[@oneoftherobs7891]

Beautiful machine. I don’t know if this guy builds bikes professionally, but if not, he probably should. Like to see what he’d do with a later model KDX.

[@stephangiannoulidis509]

So fucking nice. Quality build mate

[@kelevra558]

This thing crax like a whip. Even with a heavy flywheel. Lotta compression for c12. I'd love to see it on the new mgx02 or whatever it's called.

[@TheBurtle005]

My goodness that’s a nice bike. I’m looking for a 2005-2006ish yz250 so I can do something similar to it. I really like the frame color.

[@jeffro5032]

LMAO David......the guy on Vital is Tony. ( Great dude btw ) but he swears by the 325 kit. Second coming of Christ. And TJ , you did such an awesome job on this build man!

[@daneg]

Kudos on the complete rebuild! Quick question: I saw another 325 big bore review, and one of the negatives was that there was noticeably more shake around the handlebars because of the larger displacement. Was that effect noticeable on this build? and can you compare it to other comparable models (e.g., other big bores and the KTM 300sx? stock or modded) Thanks again! I really love these 2-strokes. I guess it's because they're all I know (rode in the 90s), but I also cannot get my head around the steep price/maintenance and weight of 4-strokes.

[@bradr539]

Ohlins 360 kit ftw... Back in 89 ☺

[@robertrishel3685]

Gorgeous 😍😍😍😍😍

[@yamahakid450f]

There's 10k or more plus the bike cost... but damn is it gorgeous. Better than a new YZ! Infact, only thing different on the 2022 to the 2006 is in the airbox and intake to get more air. Idk if it would but since the frame should be the same, he could get an intake off a 22 YZ and get more air to the big bore, or just drill some holes as long as he doesnt go over board. The brakes are slightly different in stock trim compared to the 06 but he took care of that and then some... best thing about a YZ/F, SSS forks! I've had bone stock SSS suspension straight off the showroom without even touching clickers and they were better than most of my bikes that I've had sent to Marshall Plumb. And he does amazing work. If you get some SSS suspension and send his way, it'll blow your mind when you get it back. Those forks were way ahead of their time when they came out in 2006, still the best stock fork by far in my opinion. It's hard to get a fork that plush snd still have hold up

[@deborahchesser7375]

Man I’d love to see these with lights and a big tank from the factory YAMAHA ✌️🇺🇸

Amazing yz build. What swing arm do you have on the rear? yz450 or 250f?

Ping, any idea of what the peak hp is? Can it run with stock 450's. I imagine it could easily run with them. Thanks, great video!

What kind of case saver do you have on the front sprocket. I can’t read it

I’ve had a big bore YZ and rode a few others they have a strange feel almost like they run out of steam before they should

[@leift70]

That’s where having the vertex ignition comes in like ping was saying. Without it the power curve climbs then just hits a wall

[@henricusrealms8411]

I wonder what it would do against the 450f in MX or GPs or Desert?

That bike is super nice. I would love to get one. Where did the number 13 come from? Oh I forgot, we have no point system so we can just pull a number out of our ass and stick it on. We need the motocross races to be organized and have a point system for all races

[@billp3995]

I had a 2019 yz125 and a 2021 yz125x. Kept fouling plugs in both bikes continually and not because I can't ride. Maybe the new design with the new carb will be different. Not going fuel injected in my opinion is a mistake.
