Tri-z 500?

[TexFest]

Is there ever going to be a tri-z 500 built by anyone here on the board?

I've seen 500r's and tecate 500's, but no tri-z 500 as of yet

[factoryX]

no, yz 490 yes. there was no yz500

[fabiodriven]

That's a damn good question-

[Yamada]

Do a search on the forum for Bryan Raffa's Drag Tri-Z 490

[Tri-Z 250]

There is a 500WR YZ motor that could be used, two-stroke as well as a wide ratio gear box. My question is WHY? With the 450YZ thumpers the 500cc is out. I would look to a 426cc YZ as a buildup motor (5 speed gear box)...the value of the bike is low and anything built as far back as 2002 will only pull $2800 no matter the condition. You could very well get an 01' beat bike for around $1100...sell off all extra parts and it would be an almost wash and keep the cooling system, electrics, motor and gearbox.

[Louis Mielke]

I wouldn't say that the 500cc bikes are out. Just not for a weak of heart. They can be beaten into submission, course they also beat you to death. Mine's been trying to kill me for a while. I keep getting lucky and dodge the bullets.

The big two strokes do wear you out a lot faster. The new 4 strokes are like butta. For pure power and speed its still hard to beat the big bore 2 strokes though.

[Tri-Z 250]

no doubt top speed the 5 hundy is sweet. Dune or Drag flat track sure moto I'm going 4stroke new generation YZf

[fabiodriven]

I'm in the midst of an 86 Tecate 500 build and no doubt it will be sick. I wouln't mind building a nice thumper too, though. Why not have all of 'em? It's like having your cake and eating it too!

[300rman]

My buddy used to race motocross, and he had a 500 for a very short time. he got rid of it for one reason: it has way too much power.....he sold it for a crf450.
he complained that the 500 was a wheelie in every gear with the throttle opened up. i rode his 450, and i had no problem keeping the tire on the ground on the ASPHALT ripping through the gears.

so i wouldnt say the 500 is a weak, phased out motor.....just way too powerful for 90% of riders....... my dream bike is a 02CR250 with the 500 motor in it.

[cr480r]

450's no doubt make user friendly power... But a 500 is a lighter and cheaper alternative... and can be tuned/de-tuned to be whatever you need it to be... a cheap clapped-out 4-stroke donor bike will prove to be a money pit in the long run... low hour engines=$$$

[Red Rider]

The modern 450cc 4-strokes were built to compete with 250cc 2-strokes, so anyone wanting to put a 500cc 2-stroke engine into a 3-wheeler will be unimpressed if they go with a 450 4-stroke instead.

Also of note, most people who "want" to put a 500cc 2-stroke in a trike
haven't ridden anything that big and have no idea what they're in for.

[thefox]

Didn't Chainsaw have a Z with a CR500 motor in it? It was all painted flat black.

[fabiodriven]

All three of you guys (Red Rider, Louis, and CR 480) make very good points. I personally don't think there are any 4 stroke dirtbikes that can keep up with a properly running 500. They're just ridiculous.

[Bad Karma]

The CR500 is a beast, no doubt. My 2000 CR500 has hurt me a few times... I'm starting to convert my 1985 CR500 into a 3-wheeler now. I'll post a buildup thread when I get something done that's worth looking at. :D

[cr480r]

Sand is the great equalizer... A 500 is still king of the dunes...

hehe, i beg to differ, just to stir the pot, a well strung 4 stroke will spank a 500 2 stroke in smr,,,, and bout anything else...iv had the 500's and now have a 450...it Spanks my buddys Ported, done to the nuts kx500, he went and bought a 450 too and is much happier....:beer

[200x Basket]

then your buddy cant ride.

[Louis Mielke]

then your buddy cant ride.

I second that motion, ummm. Whats smr? lol. You gota spend a lot of money to get a trx450 to even remotely touch a 500 in a straight line.

Like I said before though, the big 2 strokes take a lot out of you so its hard to ride consistently.

[tecat-z]

Well last weekend there were quite a few of us at a dirt dragstrip in three rivers, Mi. Lots of bikes there, and more 500cc 2 strokes there than iv'e ever seen in one place in my life. These bikes typically had out frame exhausts, and +8+10 in swingarms on them. Let me just say OMG!!!!!!!!!! These bikes are out of control. These riders are by no means rookies, and keeping them going straight and on the ground seemed virtually impossible. The only bike that had a shot at these big kx and cr's was a KTM SX540. With engine work, +8 arm and a great rider. Those 540's do rip, but a 450, no matter what make, will get smoked in a straight line. 2 strokes took the top 2 classes, and KX's at that.

There is either something wrong with the bike or rider if that is the case.

[MTS]

Meh, think what ya want, i see them everyday, SMR is supermoto, and i am talking bikes, not quads or anything else, a worked 560ktm will Absolutely Inilate a 250/500 on any sort of track with a pro rider,,, I like riding the big 2 strokes too, Just saying, they ain't got Nothin on the new Big bore 4 strokes.

[300rman]

the 500 is too big/heavy to really get serious with track riding. that, and it has way too much power for such a small area. the 500 was never meant for MX/SX. it is a desert racer and dune machine. go take that 500 and that 450 to the dunes and see who beats what..........the 500 is meant to haul ass for extended periods and to hill climb, not accelerate, brake, accelerate, brake..........

put the 500 into a 250/450frame and now you have a much better bike for MX, but it is still way to much HP for such enclosed riding.

[hondawasaki]

In supermoto, a 500 is too much. A 450 is almost the perfect machine for supermoto. It is not that the 450 is faster, or more powerful, it that the engine is more tractable. That is why 250F's have almost the same lap times on a lot of tracks, corner speed, and smooth power delivery.

I remember Don Canet (cycle world) running a cr500 motard in the 600cc supersport races circa 1996-1997, doing pretty damn well. They can be ridden fast by a guy that can ride.

If you have ever slung a leg over a properly tuned 500 (75-80 hp) there is no question which one has more power, or is a faster bike.

Now if were just talking lap times a guage of a bikes power. than I guess a 125 is a more powerful bike than the mighty 450's on many mx tracks......

[MTS]

Like i said, just speaking from experiance, i help build and raced (supermoto/road) a Aluminum frame cr500, It did not to bad, But it was hard To keep a piston in the thing , it didnt like sustaind High rpms all day,,, Then sleaves started cracking, clutch's where another big commidity, Everyone here runs the big 4 stroke now, i was out on a 75+hp Ktm 560, that has got some nuts,,,,,lol

[fabiodriven]

Sorry, there's no way a 450 4 stroker is going to keep up with a 500 2 stroke. It ain't gonna happen.

[Louis Mielke]

I wouldn't say absolutely no way at all. I WILL say that they'll spend alot of freakin money.

Once again, depends on the race, in a straight line, doubtful the 4 stroke will hang. On the mx track. different story.

[Epix FQX]

over here in europe we have an engine builder that makes 700cc 2strokes.
i believe he is from switserland.
Those engines are used for sidecar MX.
But imagine such an engine in a quad or bike frame :twisted:
that would houl some ass.

[Epix FQX]

here's the link to theyre website.
the company's name is MTH engines.

http://www.mth-engines.at/de/

they have 2 700cc 2stroke engines 1 powervalve and 1 non powervalve.

[rman]

Sorry, there's no way a 450 4 stroker is going to keep up with a 500 2 stroke. It ain't gonna happen.
think again , you might as well say goodbye to 2stroke its a thing of the past

[fabiodriven]

Your Mojave would be a thing of the past if you ever lined up against my 250, nevermind the 500. I'm pretty sure either one of 'em would take care of your 450 as well, definately the 500. I've had no problems smokin Z400's with just my 250. If you think 2 strokes are a thing of the past, you're on the wrong site.

1. the mojave isnt mine it is our sons

2. my 450 has smoked a many of 2 strokes including 500's

3. anytime you want to run that 250 against my 450 I live in NC

4. I have been a member of this site much longer then you know and dont care to not be a member of it actually I helped plan the first trikefest ever and happen too love 2strokes and own three of them as of right now thankyou

[fabiodriven]

Sorry, Rman. I should've thought before I shot my mouth off- I just get all riled up sometimes.:crazy:

[NOS_350X]

Wow yall shure are funny

This isnt the 80's any more, These 450's scream, The 450's arnt the old xr's of years past, Thes are screaming valve opening machines. They rev higher, and faster than the 2 strokes.

Look The AMA realized this also, They have now as of the last month taken away the "double displacement rule" This letting 250 2 strokes run with the 250f's. Look at the numbers they arnt that far off, And with the four strokes haveing more tractable power they are far superior.

A decent built 450 will run right next to the 500's.

[Bad Karma]

Good read about 2-stroke vs. 4-stroke and the AMA's role here: http://twostrokemilitia.jfn3.com/

[tecat-z]

Great stuff, and the Service Honda AF 500R David Bailey edition................ WOW. What an awesome looking bike. I will always make it a point to have fast 2 strokes. I love them. Will we ever see the next revolution in 2 stroke technology, probably at some point. When the sport of motocross is in great danger of going away due to cost and noise? Yep, sometime around then. Give it 10-12 years for them to realize the losses they have created.

[fabiodriven]

That's a good article, Karma. Although I don't race I can see the points being made here. It is definately alot easier for an average joe like me to maintain and repair a fast two-stroke than it would be to try and keep a 4-stroker going. If I could just go out to my garage and fire up my brand new super duty, hook up my 25 foot enclosed trailer, and load my 4 month old, independant rear suspension, 8,000 dollar quad to take it to the dealer at $85 bucks an hour, maybe I would do that. To be honest, I'm alot happier to jumpstart my 87 F-350, hook up my $250 open trailer, and roll my (fairly)mint 20+ year old trike out of my collapsing shed to ride just as fast as anybody else! (No offense to anyone more fortunate than myself)

[cr480r]

2. my 450 has smoked a many of 2 strokes including 500's

you obviously did not race on sand.... or else you have dumped $$$ into the 450... 500's are outdated machines in many ways... but power is still power...

[sandpuppi101]

LOL,I just gotta state my opinion on this thread.Your kinda comparing apple's to orange's in a sence.1st point I'd like to make is that I am a good rider ,weather it be on a track ,drag,trail,ice whatever,and I've ridden alot of hot set-up's from the 450's 500's and 600,balls out ,and I believe other's can vouch for my riding skills,and I have too say that the 500 is in a league of it's own .Your looking at a totally different burst on any pinger,and a 500 is explosive in many situation's,tire's go to spinning and it's finding the happy medium ,to where you can perform with it.Now a 450 or even a 600 are powerful and fast also,but don't have that explosive feeling that the 500 would offer.Instead ,the thumper's give torque,and there again it's finding a happy medium with the torque.Gearing is also a huge set-up when you run these machine's also.As all you guy's know there's ton's of variable's that could change the performance in any machine,but I ain't ready to say that a 450 thumper is ready any time soon to be spanking a finely tuned 500 pinger.I don't miss the vibration from the pinger 500 though,but that's another conversation by itself.

[rman]

you obviously did not race on sand.... or else you have dumped $$$ into the 450... 500's are outdated machines in many ways... but power is still power...

nope obviously not seeing I live in north carolina:lol: like many have said it depends on what riding your doing and I ride mx and woods riding. and yes there is many variables in it including the rider. and yes I have put some money in the 450 but not anymore then most spend on there 2strokes

has anyone looked into putting a YZ500 top end on a triz 250 bottom.?? if I had the parts I would check into it.?? I know two guys that are good with crazy stuff like that. I'm picking up a blaster this week and plan on putting a YZ490 motor into. if anyone knows someone with a yz490 motor, exhaust , carb,??
please let me know.

500 & 600cc snowmobile jugs look exactly like banshee jugs im looking into building an oddball hybrid if the 600cc jugs will slip on a banshee trans & will slip into my tri-z frame. sweeeeet :naughty:

[The Goat]

louis I know I can't ride one...I know I can't ride.

But I STILL think that a 500cc 2stroke trike would be the tits for the long long gravel roads around here.

Now I won't lie... just a gsxr600 was enough to make me swear never again the first time I rode one... but going fast for a long time is what I like...and a 500cc 2 stroke is what it would be for off road

[audioworks04]

I agree that a 500 is an amazing power plant, but as anyone who has ridden the 450s know that they rev almost as fast as the two strokes of the past and put down power everywhere. I think it is all just to each his own and ride what you want, or better yet build both. : )

[Cadaver Dog]

I realize this thread is kind of dead as a doornail but I was just thinking that from what I read as A lad in things like Dirt Rider etc in the 80s is that the YZ 490 wasn't really as up to snuff as it's competition.

[300rman]

Wow yall shure are funny

yup. the 450's are screaming valve-eating machines all right!

y wouldnt you just keep the whole 500? dosnt the 250 and 500 sit the same

[jeffatc250r]

The 97 and up cr 250 have an aluminum frame. This has become a common thing for people to stuff a cr 5 into a modern chassis.

[HIK6911]

Is there any way to bore a 60 cc into a 500 cc? LOL!!!

[volfan537240]

2 strokes will always be faster than 4 strokes hands down! its all in the mechanics. yes 450's are pretty mean from the factory but dollar for dollar the 2 stroke can be built faster than any 4 stroke!

[3wheelmecca]

I'm with it. Ive raced side by side my 1990 KTM 500MX against a NEW KTM 525SX and beat it...by a longshot. they were both stock.

[300rman]

The 450's arnt the old xr's of years past, Thes are screaming valve eating machines. They rev higher, and faster than the 2 strokes.

A decent built 450 will run right next to the 500's.

fixed your quote.

and the AMA still does not allow 250 pingers to run with the 250 pokers in PRO racing.....

250 vs 450....hmm i wonder who would win....thats one hell of a handicap!

125 vs 250f......hmm.....double displacement? what a handicap!

450 2 stroke vs 450 4...that would be interesting. and i dont mean old tech 2 stroke....get a few hard years R+D into teh 2 stroke again and see what happens.

[Darius1502]

how about a KTM 550?133484

[lazybiker79]

hey guys... I've been thinking about building a tri-z 490, Since I have a ATC500R and KXT500 it would complete the collection :w00t:
Im going to start it next year.. I'll keep you posted. AS for the 450's... I've raced some with my 500's they didn't stand a chance :lol:
