This would make a great starter bike for my little sister.

sarcasm not with standing, I'd take this bike in a second. Don't let this small video sell the bike short. Having sponsored a two bike team through the 80's, you would need to see this bike ridden by someone accomplished at a big track, wide open!!

Incredible piece of work! I'd love to get a ride on it. Two-strokes forever!

183BHP yet just 124KG, SICK! I've spent last few weeks thinking about this exact type of bike, using a Polaris twin engine. Got diverted thinking the 4 stroke, 3 cylinder, 1200cc jetski engine as prefer 4 strokes myself for road. Though with things like Aprilia RSV4 with all the electronics included for reasonable costs, why bother unless I NEED to stand out. This guy works for F1 team, so not short of engineering ppl/machines to take advantage of ;-)

I admire the mindset of anyone that would stick a highly tuned 800cc 2-stroke engine in a motorcycle chassis. Beautiful bike.

the Tularis raced at Mid America Motorplex (no longer exist) back in 03-06 -- it was amazingly fast and sounded great! Mr Tuluie the builder was easy to interact with and we enjoyed him and his Tularis -- good memory

that thing seriously brings a tear to my eye, so beautiful =']

I LOVE a big stroker!!! Love the way they dump all their horsepower onto you in that one instant. That's why I've still got my RG500 after 25 years.

Do you still have it, she'll be worth a mint now

beautiful, that is a beautiful bike. Wow, post more soon.

That is a Wicked Looking Bike. I personally want a two stroke 500cc fuel injected 1995, BIMOTO to play with.

Those are awesome depending on the year. Its the Bimota V-due. I'd recommend one of the later years. the early models had some issues.

wow ,great work and keep them comming

the blue things are tire warmers and it sounds amazing! its a 2 stroke so basically like a chain saw engine but its 800 cc! that thing would be a blast to ride!

gotta love the 2stroke sound and smell

Tj1056 it is an 800cc Polaris Snowmobile engine (Liberty Twin) XC 800 in about 03 or so. It is turned around as the flywheel in now on the Left side and exhaust is facing rear, depending on the gearbox possible its rotating opposite of the tires, though 2 can strokes run either way!

love that exhaust system

make me remembered those good old days with my 2 stroker motorbike.. amazing... ^^

What an angry beast. I love it.

It makes me happy to see blue smoke coming out of one of those bikes

i have an rz350 and i love everything 2stroke but i am 100% sure that i would die riding something like that. i would love to see this in a drag race... more vids please!

nice piece of machinery!

Was fun seeing that thing race around Blackhawk Farms years ago for the CCS/FUSA races. It was insanely fast on that track before the repave. Wish they would had brought it back after BHF was repaved to see what it could do on a smooth BHF.

i read the article in a magazine in my english class it was way more interesting than my lesson lol

Yes, i agree. I am currently working on a reverse 2 stroke drop valve briggs and Stratton half shaft rotary drop plug horizontal steam trap at the moment but it just wont fit into my NSU Quicklys frame!!

they are called expansion or resonant chambers, they make a reprociating pressure pulse that sucks burned mixure out and keeps the fresh mixture in

awesome

thanks....

The trick is to keep stuff from not exploding. The 1.5 turbo formula one engines that produced over 1400 HP didn't go for more than one race, and that was when detuned to 1000 hp.

yep one wild ride

That is not a bike, that is a rocket!

i love the old 2 stroke diesel screamer engines. Especially "Detroit". Sick

we are all need for 2 stroke speed!!! respect to the 2strokes!!!

very nice bike. i want one

they used to in the 80's the rd500 v4 2 stroke and the rg gamma 500 2 stroke both were awesome

It has an titanium expansion chamber. Titanium changes colour to blue due to heat and because the heat is highest near the head pipe, that part will be blue first. Other parts will likely turn blue after some use.

@NastytheGREASERZOMBI Only reason I know that is this bike showed up in a number of printed and online articles about ten years back that went into a fair amount of detail. Having an 800cc two stroke out of a snowmobile (I seem to remember it starting as a mere 650, but could be wrong) is the least remarkable aspect of this bike, which is why I shake my head at the two stroke/four stroke arguments on here. The bike was an exercise in taking power to weight and lowering the CG to the extreme.

GSX-R-750. A friend of mine has one he crashed, so the engine/gearbox I can take. I will use a reputable tuning firm in Sweden to strengthen the gearbox, clutch, driveshaft, and to separate the gearbox from the donor engine, do all aluminum welding and so on. They've made extreme machines before, traqnnys for drag, bulletproof clutches, custom-made transmissions, powertrains, rear frames, fortifications, suitable geometry/suspension and so on. EBOS in Malmoe, Sweden is the company's name. : )

183 horsepower, with a 2 stroke powerband. thats just sick

I love the sound of absent technology

o my god.. the beautifull engine sound that only a two stroke can have...

Love the sound especially in a pack

This is why I love my banshee! 2stroke fucking rocks!!!

Or of coursem the english legendary bike builder Alan millyard. What he doesn't know about making hybrid engines, bikes, gearboxes, can't be worth knowing, hehe. Have you seen many of his bikes? Completely brilliant, from 4-5 cylinder two-strokes to forstroke V-10s and V-12s of various kinds. The guy's a mechanical genius:)

@epiphonesg007 500cc 2T racing bikes used to have 4cyls. Consequently they had 4 separate expansion chambers (exhaust pipes), too.

@SuperEarplugs No, for a 2010 KTM exc or sx fourstroke, Oil and filters is every 3 hours or 21 litres of fuel. Engine disassembly is recommended every 40 hours. It takes 1.1 litres of oil, so it uses far more oil than any 2 stroke, plus a filter. (which for my mate's 400exc is about 40 bucks as it has two filters that need replacing). You may have a different model with different requirements.

fastest weed whacker in the world...kidding..doesn't sound like much but it's an incredible piece of engineering

@Revanche2strokes I admire your thorough and pointfull message. May I ask, what is "FI"?

I have ridden this and it is insane. The host does not quite explain why this is very well. The fact is it jumps 50hp in 500rpm. It is scary when this happens and makes you really respect the old gp riders who used to race this type of motor for a living. It throws you off and makes you ride alot slower than normal. As you can see from the video the host was tip-toeing through corners and it is very understandable.

@copsinmyhouse powerband means a certain range of revs/min where the engine doesnt make a loss of petrol-oil mixture which allows HEAVY Pull right away.

check out the exhaust! Thats pretty crazy, what bikcs does this run with? 600s or 1000s or what?

They also do stage 1-stage 4 two-stroke porting, so I'll give them my templates for race-porting of the twin, and see if they can improve on the porting further. Or reeds, chambers, squish bands, carbs, ignition, they have decades and decades of experience, both in racing and street-tuning of strokers: )

I'm doing the same thing now with an old 900 twin Suzuki snowmobile engine and an 84 RG250 at 140kilos.. I will port the skidoo-plant to the max, wisecos, welded crank, bigger reeds, good, noisy chambers and a clutch/gearbox to take 220hp at least. Frame must be fortified, wheels, dampers bigger, tall gears, forwards-leaning posture, longer rear swing, but it'll still be a tiny bike! Maybe for fun just put "125" stickers on it, hehe!: )

I red an article that some new two strokes were getting less emissions than four strokes but the fact is, a 2 stroke burns twice as much fuel as a four stroke.

Wow! What did they use as gear-box and clutch on that thing?

two stroke, true smoker, true power.. this is a beast machine.. 4 stroke user will hate this statement.. my advice; try 2 stroke, then I guaranty you will change your mind.

Love teh straight pipes

that bike is fairly old now but the dr is a legend!!! is it still being developed?

@dementedx i agree, the skidoo mach z 800 makes like 180hp with a set of pipes, for a tuned race engine this could be pumping more than 180hp. but its still one hell of a machine!

@GSG1298 because its tuned that way. some port work could have that thing hualing in low RPMS

@FocusASBO probabily because it's a bit bigger of normal 2 strokes ccs (125-250-750cc) that is 800 so there are 2 cilinders with 400cc each it's pretty big and also i think it's because it has a bit more of torque than a normal 2 stroke cilinder

What kind of transmission does it have? Is it snowmobile style? (I saw a belt) but i am confused because they look to have push started it.

man they need to make more 2 stroke motorbikes.

those bikes are illigal in our country both on street aswel as on circuit just because there so powerful and unpredictable but they are sooo awesome

Ummm ok... Those jumps and ramps on the tarmac are insanely huge! They must have serious balls!

I came. that's a pretty sweet running piece of machinery.

does it have a cvt from the snowmobile or a clutch type transmission?

that is the single baddest bike i have ever seen.

gotta love the chainsaw exhaust note.

Mind you, I've been offered an Arctic Cat thundercat 1000 triple for cheap. They are not made anymore, but parts, tuning is abundant for those wild monsters.Kits of 1200cc or even more,300HP easily, but then I need a big frame for the triple stroker and three huge expansion chambers need to be squeezed in somewhere,maybe one above the cylinder block and one to each side or something?And a Busa tranny or a drag transmission maybe?But that would be years in the future anyway,I'll do the twin first

Any know that music, it's The intro music from an old mmo. Neocron.

thats bad ass!!!!

I rode a TZ750 on the track a number of years ago, and must say, two-strokes can really make power fast and hard. I still prefer a 4-stroke engine though. There you have it!

Scary machine indeed. I wonder what is the fuel eonomy of it.

wonder how he hooked up the transmission?

0:40 is there no problem @ the caburateurs? because the front wheel can trow grid or something in the airintake of the caburateurs, or can't?

That's exactly my point....a snowmobile transmits power through the belt from the primary clutch to the secondary and on through the chain case....however there is no single component known as a "transmission". This engine just has a tapered end on the crankshaft. In that case there is nothing "normal" about having a sequential gear box on that engine. almost all sport bike engines have the transmission and engine in one piece. Someone had to have adapted the engine to some sort of trans.

He said it has no low end power. Does this thing not have exhaust valves like on a yamaha rd ?

@SuperEarplugs You're quite right, it is a misunderstanding. Piston and rings need replacing at 15 hours not 20. Honda states that this "is based on average riding condition. Machines subjected to severe use require more frequent servicing"

Thundercats were SO popular, so many were sold that you'll find a sled or a motor too. Test a Car,motorbike sales site like e-bay, just in your own country, and I guarantee you'll find many!

What gearbox will you go with?

why did they even bother to mount the front tire? lol! I just love this!

Hehe, great! "No power below 5000 or above 8000"..that's how a two-stroke should be, too! It's what makes them exciting(or scary) to ride! Awesome video! : )

just had an idea. I'm gonna make one of these and use my sled's 800 in it, when winter comes around swap it back! 1 engine, 2 rides!!!

Love the two strokes. Wish they made 500cc race replicas.

what kind of clutch does it have?

@mcturk17 in a two stroke, the piston lowers and basically pulls gas/air mixture in with the vacuum of the piston going down, then the momentum makes the piston go back up and compress the gas and air at the top of the cylinder, then spark and the explosion pushes the piston back down and the exhaust is pushed out the exhaust port with the explosion. A 4 stroke does the same but lets the exhaust out half a revolution later. 2stroke= up down 4stroke= up down up down

hitting the powerband in that bike must be scary as shit

I know robin tuluie and he was telling me about the time that he did this test with the MCN Guy and apparently the guy testing it was a complete knob he was like ive ridden motogp bikes this will be slow in comparison and robin warned him but he just nah it wont be fast then when he came back he was quiet and basically shit himself anf robin was like i told u so hahah great story robin also has a 500cc supermoto that he rides offroad as well as onroad where he beat factory teams with a prototype bike robin is one of the smartest people i have ever met

You need to tell Dr. Tululie he needs to put up a couple more videos of this bike. I've been reading about this bike in various print and internet magazines since the 90's and this crap clip is all I've seen and heard of it's running and race history.

That's an amusing story! MCN guy, you ain't all that OK?

@JuniorPros118 and this only have 2 cylinders at that! Its amazing

A direct-injection two-stroke does not require pre-mix, from what I under stand. Either way, many two-strokes have a system that automatically mixes oil with fuel, so you simply have to keep stocked on that, which should be no more of a problem than filling up with gas. There's a video on KZread that talks about DI two-stroke oil requirements for Evinrude outboards, it's something like, "2-stroke vs 4-stroke outboards part 2" or something.

@factoryXperimental hahaha! love it!

he's getting on the bike like he is scared as hell of it :P

@JuniorPros118 a gp bike, wich is a 800cc 4stroke, makes about 230cv ;)

How many strokes was it again?

where or wich is that circuit/track?

On the track: vroom..vroom..vroom...BRAPPP!

4 stroke fan boys.... Long live the 2 stroke!

And to REALLY put that in perspective, the gas engine of a Prius is a massive 1500cc, spread across four cylinders, and only makes 76hp. You would think they'd try to be efficient with space and weight, but apparently not. I think they should make a switch to the direct-injection two-stroke design. You're getting more power from a smaller machine, with equal-or-better fuel consumption to a same-horsepower 4-stroke. They'd get big weight savings, and a very cool noise. Why not? :-D

brings memories of my Yamaha TZR 250 R (3xv) i had some years ago

Imagine a 2stroke with 4 cylinders....make the powerband higher. And you've got yourself a killer bike. After many many many months of developing it lol.

What is this race series called he speaks of?

sick...
