Turning a Suzuki DRZ400 Dirt Bike into a Street Tracker + The Best Test Ride Ever

This bike had initially been bought for some off road trail riding, but after a couple years of that, our customer wanted something a bit more fun on the streets.
Watch how we turned the DRZ400 Dirt Bike into a Street Tracker. Needless to say the result was awesome. Check out the test ride at the end of the video!

This looks insanely cool! Great job!

[@PurposeBuiltMoto]

Thanks, appreciate that!

[@ericweber1969]

Wow, that's AWESOME!!! Just the kind of bike I need in my life!

[@PurposeBuiltMoto]

After the test ride I think everyone needs a bike like this in their life

[@ericweber1969]

Purpose Built Moto well said. Looking forward to seeing the front fender setup kit, that thing is beautiful! By the way, what the hell is that air cleaner?!? It looks like it ate Big Bird! 😁

[@l.a.raustadt518]

Oh yeah light and right. Sweet!

[@NowhereFastADV]

As usual nice work mate.. kinda wish I stuck with my drz tracker.. can't wait to see what you smash out next..

[@PurposeBuiltMoto]

Cheers Shane, did you build a tracker yourself? This one was so much fun

[@NowhereFastADV]

@@PurposeBuiltMoto gave it a shot but stopped short of the custom subframe, those 400s go hard..

[@PurposeBuiltMoto]

Yeah enough go for any sort of riding you want to do, in a light weight frame you can’t go wrong

[@MereroFishing]

Hello brother. Very good project. This is Very beautiful. Hugs from Brasil

[@PurposeBuiltMoto]

Thanks Mate!

[@major1388]

Sick bike! Id love a custom build like it.

This one is a real all rounder that everyone could enjoy

Love this! well done guys

Thanks mate, do you have a DRZ?

[@cudarsjanis]

@@PurposeBuiltMoto I had 701, but I`m planning to get old DRZ for this kind of project.

Well done indeed. Looks like tremendous fun! Any idea what the seat height ended up at?

[@PurposeBuiltMoto]

Ah we never measured that mate so I couldn’t say.

[@flfreaks3745]

Nice built. Would be more great if you have a friend to record of you riding it. I want to see the bike full body on the roads

[@mikecosgrove7582]

Friends don't let friends ride seize-ook-ies Bad ass build though🤠

[@Jay-mz7dr]

Very nice, I really like what you have done with the DR. I had stopped putting my WR450 2007 project bike back together a few months ago as I was considering if I could convert it into a street tracker and because I had already done a WR450 project full refurbish previously. I wasn't sure how to tackle the subframe, but now you have inspired me to re look at it. Did youhave

[@PurposeBuiltMoto]

Great to hear man, have fun with it!

[@Jay-mz7dr]

@@PurposeBuiltMoto The last part of my comments didn't load (dodgy internet I guess) I was asking how you lowered the bike over all. Ddi you say you used front and rear 19"wheels? and pushing the forks along way through the triple clamps + building up the mount for handle bar clearance? And to stiffen the suspension I assume stiffer springs and adjustments?

[@PurposeBuiltMoto]

Yeah mate there’s a bit in it to lower the suspension but can be done by a good guy that knows his way around it. Hit the link in the video description and read the blog it has a bunch of finer details for you

[@rileywallace1132]

I'm not a Cafe racer guy but I love this build. I'd love to see a sumo/bobber mix.

[@PurposeBuiltMoto]

Thanks mate!

[@danielkiebert7528]

Reminds me of days riding through Mount Glorious

[@ericweber1969]

This bike is really inhabiting my dreams! Here I am, 5 months later, watching the video again! A question, what machine did the radiator come from? You mentioned an ATV radiator, you wouldn't happen to know which one, do you? Thanks!

[@PurposeBuiltMoto]

I don’t have the details on the radiator sorry.

[@ericweber1969]

@@PurposeBuiltMoto no worries, man! I’ll figure something out when the time comes. Lots of good options out there.

[@trevorleggo1777]

Very Neat...

[@mohammedmidlaj4623]

Nice 👍👍

[@samteebo1994]

Fantastic build - I couldnt spot the battery in the video, where did you end up squeezing that in on such a minimal build?

[@PurposeBuiltMoto]

Thanks mate, the battery is hidden under the seat

[@grahammoore9341]

Looks great! Had planned something like this some years ago... But went and bought a Bonneville. Wish that I'd stuck with it. Is it simple to recal the stock speedo for the new wheels?

[@PurposeBuiltMoto]

Yeah it’s a fun bike for sure. If we did this build end to end I would have done a custom speedo and calibrated pickup. We didn’t mess with this speedo so it’s out, from what I tested about 10kms at 90km/h The rider told us not to worry about it

[@ericweber1969]

Graham Moore graham, I don't have a DRZ (yet!), but I've read that the speedo can be recalibrated fairly easily.

[@bigdawgggbachi5394]

Man that thing was way cooler when it was just a normal drz!!! Drz for life!!!

[@PurposeBuiltMoto]

Thanks man! ⚡️

[@bigdawgggbachi5394]

@@PurposeBuiltMoto just a little trolling definitely a cool build I couldn’t resist. There’s just not a cooler bike that exists than a regular drz that’s all! Good work fr!

[@welly706]

Looks fun. The dash/speedo is a low point though.

[@Sharkytac]

I’m looking to this to my DRZ over the winter. I feel like the biggest challenge will be finding the right tank, would you guys be able to point me in the direction of one that will fit? Trying to avoid too much heavy fabrication for my first custom build.

[@PurposeBuiltMoto]

The DRZ has a slim back bone so just about any tank will fit. No matter what you’re going to have to make brackets and mounts for it though

[@jvogler_art4708]

i WANT it. ive rode nothing but dirt bikes my whole life and all the street bikes i see just seem so clunky and heavy. I like a light weight low profile bike like this. Also being a 400 4 stroke that thing is gonna have some POWER! with a broad power band too!

[@PurposeBuiltMoto]

Yeah it’s a super fun bike! If you want one made hit us up!

[@andrewdelturc4098]

awesome bike. im working on doing a similar build what size are the tires?

[@PurposeBuiltMoto]

These are 19" front and rear. 130 wide standard flat track tyres

[@joep6461]

This Bikes awesome! What's the radiator come from ?

[@PurposeBuiltMoto]

No idea sorry made, the owner did that mod.

[@atomariel4849]

I wish I knew how to squat the bike lower to the ground... I am not sure do you get a different front fork from like an r6 and a shorter spring for the rear. I just want that hypermotard look with slicks just naked and mean.

[@PurposeBuiltMoto]

There's plenty of options available to lower your bike, especially with dirt bike suspension. just have a search around

[@breadring]

yeah nice job, so exactly what tank was used ?.

[@PurposeBuiltMoto]

breadring it was a tank I had laying around the shop. I’m not sure what it’s off

[@zeno1inH]

Whats the price would be if it was for sale ....

[@kymcopyriot9776]

Nice work. Now drop a tooth on the countershaft sprocket and let’s see some wheelies!

[@coldee785]

What did you use for spokes? I'm looking at doing the same thing and trying to decided on stock rim sizes, or go 19" like this build

[@PurposeBuiltMoto]

When you’re doing a custom wheel swap, find a local wheel builder and they will make the spokes to suit your application. You can’t just buy them in a kit

[@coldee785]

@@PurposeBuiltMoto I was afraid of that. Unfortunately I do not have a local option. Thanks for the response 👍

[@PurposeBuiltMoto]

Neither do we really, but you give the closest guy a call, send them your wheels and they ship them back with the new spokes and rims

[@TheDelecolle]

Congratulations, beautiful bike! May I ask you the specs of those 19" Excel wheels? Are those 19"x2.15" on the rear?

[@PurposeBuiltMoto]

Yeah mate that’s right. That size it’s typical flat track set up

[@TheDelecolle]

@@PurposeBuiltMoto thanks for the info!

[@mtphelmond]

Can you just fit that into the standard swingarm?

[@PurposeBuiltMoto]

@@mtphelmond Yeah you can, The swing arm is no problem, the front end is really tight though.

[@aaronfrederick23]

What is the width of the Excel 19" rims? are they 3" front and rear?

[@PurposeBuiltMoto]

From memory they're only 19 x 2.5", maybe check the build blog out I may have written it in there. link in the description.

[@ourgreatestexpression]

Would love to see this done with a WR450 !

[@PurposeBuiltMoto]

Oooh, me too!

[@darmiejr]

Suzuki should had made this bike. They came out with the TU250 and that's an awesome bike however, it was always a bit under powered. You had created a nice street bike with the 400 engine that should had been available a long time ago. I'd say your gearing is a bit on the low side probably a 15/16 front with a 39 on the back? Sure looks good.

[@PurposeBuiltMoto]

I think you meant to say the gearing was a little on the fun side 🙌🏼😅 thanks all he same

[@coldee785]

What air filter is this! It's awesome and I want one

[@PurposeBuiltMoto]

It's an aftermarket Unifilter I think for the DRZ400, you can get it from MXstore.com.au

[@coldee785]

You are awesome, thanks so much

[@ronanrogers4127]

Now all it needs is the stroker, big bore and wide ratio gearbox so it’s got 50+hp and sits on 120 at 5100rpm

[@PurposeBuiltMoto]

That sounds like a mighty stage 2

[@DITCHmoto]

Please, I need to know what tank that is!

[@PurposeBuiltMoto]

I Nust had it laying around the shop, I dont know what its from sorry.

Ok that’s fine. How about making a couple of those exhausts and selling me one!? Please!

[@DickDebonaire]

Very nice. I have a 2006 E model. The final year before they strangled the engine with California required emissions here in the US. You mentioned the suspension is stiffened up but don't tell if the shock and forks are internally modified. If not, with the fork tubes slid so far up the triple clamps couldn't the lower fork tubes or front fender bottom on the triple clamps?
