Turbo Supermoto?

This is new supermoto toy. It is slow.

Is this a good idea?? MpFab Kit..

You might be better off getting a faster bike.

Turbo on anything is a good idea

ANYTHING :party:

I seriously would rock a kit like that on my CR250. That is fucking awesome.

EDIT 1: The only concern would be burning my leg on it because it is not isolated very well.

EDIT 2: I would also be concerned with what happened to it when I fell. Is it durable?

MP Fab is in Birmingham, about 2 hours from me. His work is stunningly nice.

Turbo WR250Xs are silly, though. Buy a YZ450F and put a plate and 17s on it, or put a Millenium big bore in a DRZ400SM. Or strip all the extraneous nonsense off a Versys (mine is an absolute ball). All of these options would be cheaper, faster, more reliable, and less trouble than a turbo WR-X.

BUT IT HAZ TURBO!!!!!!!!!!

Dude, that bike is WINNING. +1 turbo on anything is awesome. not sure if it would be worth your trouble though.

I've contemplated the same thing on my buell.. several people have made 150+whp with them that way.

Everyone running the same kit has had no complaints about heat, none that header wrap couldn't fix at least.
Plating anything that doesn't come plated is near impossible. I live in California. The next step up in displacement area for a stock supermoto (everyone around here has DRZ400's I want to be a little bit unique) is Husky and Ktm area which is big bucks.

A week ago I just got a Suzuki DR350S for...well...Free. :party:

The first thing that came to mind was "Hey, I could spend $500 turbo-ing this and it would only be a $500 motorcycle, this is a really good idea".

DAMNIT.

See what you did? I just spent the past hour and a half finding the cheapest place to get a used tiny turbo from.

This website is very useful BTW:

:crx:

1.) You can get an ~05 525SMR for under $4k all day. KTMs aren't that high.

2.) You can usually get Garrett GT12s and GT15Vs on ebay from FSAE teams for really cheap. Garrett gives a free one to any team who asks every year.

I had a local selling the exact same bike and turbo kit... i REALLY wanted it.

Do you have a 2 stroke or 4 stroke?

This thread makes me miss riding my YZ 450. That is still the best motorsport fun I ever had.

Not where I live. If that was the case I would of had one a long time ago haha.

I also just sold off my welder and all fabrication tools, I have a tiny 1 car garage now with no room for anything. It would have to be a prefabbed kit.

One day I'm going to do that to mine. On completely stock internals they hold that kind of power all day long. The same guy made 185whp with forged internals and lower compression. The ECM is fully tunable from the factory and has unused imputs you can add a map sensor to. Relocate the AIT sensor, use speed density and tune it up!

His most recent setup completely hides the turbo under the bike for a good low CG and stealth setup.

Although I have enough trouble with my turbo miata, and at least my bike is stone cold reliable.. so i probably shouldn't attempt this.

I have a 2 stroke which I trail ride. It is not ideal for what I do but I got a good price on it and the fact that it is a bit harder to handle on the trails has made me a better rider. When I get on my brothers YZ250 I feel like I can go wide open all the time because it is so much easier to ride.

After 12 seconds on search tempest, here's a plated 520EXC SM in Chatanooga for $3300:

2002 KTM 520 SuperMoto


I bet he'd take less, and shipping a bike is cake.




Actually, I might buy it, haha...

I'm not trying to be contrary, just pointing out that options exist.

Have you ridden the 4 strokes yet? It makes riding sand fun again.

Yah, what bike do you trail ride ?

Ive ridden 250 two's and have had a few 4's. I ride a YZ450F and love it. We also have a YZ125 with mods for bottom end and its just so flickable but on a long grungy rocky mountain climb it starts to lag. I just put a Rekluse on my 450 and its amazing. I purposely stop and try to go again on hills just because I can with no drama. Haven't had it out to the mountains yet but soon soon.....

Motocross bikes are my favorite motorsport right now (and last 10 years)as well. No rules, unlimited scenery, and with a 450 always "all of it" power.

My brother's yz is a 4 stroke so I guess that makes it a yz250f?

I ride a super clean 99' Honda cr250. It is incredibly fast but I have yet to fully setup the suspension for trail as opposed to track. It is scary in 4th wide open in sand. I can toss it around very easily because it is light but it just is not very confidence inspiring with how squirrely it can be sometimes.

As I said when I get on my brother's 4 stroke and he rides my bike he cannot keep up because I have learned to ride fast on the trails on an improper set up so when I switch to his I can just blow him away. I've thought long and hard about trying to trade for 4 stroke cr250. Not sure just yet if I want to because I actually like the 2 stroke motor a lot.

SO

MUCH

WANT

:drool:

I have been out of the game for a few years now, miss it terribly sometimes.

I had a YZ450. I owned Jason Thomas's Pro AMA supercross bike that he retired, a 2000 YZ250. I picked it up soon after it's retirement. I broke 2 collar bones and almost cut my finger off with that bike, among other incidents. All in one year. Good times.

Funny thing is that when I got the new 450, I rarely crashed. I think that the 250's chassis was worn enough that it was too loose handling wise. I would say that the 450 was as fast as that worked over 250 if not faster.

Before I am too old, I would like to own a KTM 525.

Wait till you ride a 450. It is intoxicating.

I'm in California. I'm not shipping anything that size. I have to be able to ride it home, no more than 2-3 hrs away.

Update:
Kit has been purchased. Along with some other minor upgrades. Mmm boost..

Seriously? Fucking awesome. Please make a build thread for it.

This is going to be interesting. At first I thought this was a dream thread. Didn't think you were that serious.

I make impulse purchases sometimes. This is one of them. Hahah.

Teaser.

Dude. Epic. Awesome. Yes you'd be better off to buy one of those other bikes but this will be COOL.

And that turbo Buell... EricZ's bike. Watched an on-bike vid of it the other day, it's nasty. Hearing it made me miss my Buell soooo bad!

Don't know if you know this, but Erik Buell was actually building a turbocharged Buell for production. The XB was originally conceived to be a turbocharged bike, and they got pretty far into development when Harley pulled the plug. '03-'05 XBs have a vertical hole in the left side frame -- that was originally meant for a boost tube as used on EricZ's bike. Erik had the bikes putting out 150 whp and 120 wtq with factory-level ridability. If he had built that bike... If only Harley had let him build that damn bike.

Assholes. I don't swear often but when I do it's likely in some way related to Harley-Davidson and their asshattery.

/threadjack

you should put nitrous on it too

Agreed, OP's impulse purchase is awesome. This little bike is going to be so damn cool.

In regards to the Buell turbo thing, yup I'm aware. This is why the ECM already has unused inputs and can be adapted to using a map sensor so easily. Also the hole in the frame, mines an 04 chassis so it has the hole for the charge pipe to hide in. This is all part of why i really want to turbo mine one day. Turbo bikes are fascinating.

Only local motorcycle tuner with a dyno said he's not familiar with turbo bikes at all. What do I tell him to look/do differently than tuning a NA bike?

Uhh, watch out for boost? LOL, seriously though timing needs to be retarded more than a na bike among other things. Be careful with that tuner, maybe take it somewhere that can tune it properly.

on a side note i youtubed that turbo kit. looks hilariously awesome to me.

Most of that is him snatching on the bars as it comes into boost in 2nd and 3rd. It's not as violent as he makes it look.


It is still significantly faster than stock.


What are you using for tuning? A Power Commander? Do they even sell a Bazzaz for WR-Xs?

For the record, I DO think this is cool and applaud your ability to say Eff It and buy the turbo parts. I'm way too analytical to just drop coin on a kit like that on a whim, lol.

Power Commander III. Basically just adjusts fuel.

Tear down and cleaning has just begun. Trubo should arrive next week.

Also just picked up a kitten. Some Miata owner had 100+ cats in his house. Humane society is still running at full bore so I helped them out a little.

Got it running, took it around the block to check for leaks and to let it warm up (stayed out of boost). Came back and let it cool down for 2 hours, went to check exhaust bolts and turbo bolts and I snapped exhaust stud off in the head. Sad face. It will have to wait longer for boost now. I have to tear everything off tomorrow and hope I can extract the stud easy enough and find a replacement at a hardware store since all the bike shops are closed on Sunday.

Forgot this one:

Check the HELP section in the auto parts store. I got metric carburetor studs that I used on my last DIY turbo build there.

What is the 'HELP' section? Dorman products?

First start:
http://distilleryvesper7-7.ak.instag...1f9be1_101.mp4

Just the generic section in the auto parts store with general do-dad parts that would fit multiple vehicles. Either Auto Zone or Advance auto actually calls it the HELP! section.

Oh ok, I'll be sure to check it out once I get this damn stud out. Went through like 3 drill bits getting a hole in this fucker for the extractor bit to fit in(stud is made out of diamond or something) and the extractor bit snapped off flush with the end of the snapped stud at my first attempt to remove. Great... lol. Torch and vice-grips aren't cutting it either. Ideas? I have clearance issues, it's in a tight spot.

That is pretty much a worst case scenario. I think you will have to face the reality that you will have to pull off the head.

https://www.miataturbo.net/attachmen...ine=1375289139
I'll just leave this here.


I can't find a factory torque spec for the exhaust head studs. Anyone have any suggestions? They're M8x1.25 and about 2inches long roughly. I torqued them to 15ft/lbs I'm gonna run it through a couple heat cycles then re-torque.

Brain, I made sure the picture quality was up to par for you.

Dude.. it's so awesome. Fuck you and your boosted 2 wheel hooligan machine. Do want.

I wonder what would happen to a photo if you uploaded it to instagram, saved the picture off instagram after uploading it, re-uploaded it to instagram, etc. Rinse and repeat 100+ times.

Would it just be a grainy blurr?

Fuck this thread. Makes me want my KLX250SF again. I want one so badly!

https://www.miataturbo.net/attachmen...ine=1375304154

The one bike I always wanted was a KTM 525. I just went to the KTM website, and it looks like they are not in production anymore. That make me so sad.

I'm gonna neg prop every response that doesn't solve my torque spec issue. I'm scared to snap another stud.:vash::makeout::makeout::makeout:

Depends if it is a 8.8 or 10.9 rated bolt.

I looked it up for you. An 8.8 rated M8-1.25 has a torque max of 18.75 ft lbs for Zinc plated and 17.25 ft lbs for not plated.

A 10.9 rated bolt would be 27.5 ft lbs for zinc plated and 25.5 ft lbs for non plated.

Edit: I tested the link and it did not work. Because pdf?‎

My dad bought a KTM 525SX and I took it to the dunes once with the standard knobby. I could keep up with 250 2 strokes and such with their paddles. The thing was a total monster.

Carry on with the awesome turbo supermoto/brain provoking.

This thread has me searching CL for a wr250x...

I'd have to sell the miata to afford one though.

I would rarely use something like this, but man it would be awesome those few times.

Please share more pics and videos.

Does the kit come with engine management, or can you just re-flash with the power programmer?

Awesome
