- Today's video is about an amazing racing motorcycle built in a basement. His feature is a unique snowmobile engine that surprised everyone. More details in the video itself, today it is very interesting. Have a great mood and enjoy watching!
I raced with Rob during his WERA years back in the 80’s, while he was teaching at PENN State. He raced several of my two stroke bikes back then including my TZ750. A good lad and incredibly brilliant engineering mind… Truly the wonder years….
I met Rob in 1994 at Summit Point. I helped unload his Tul-da 500 and a TZ750 w/GSXR wheels (and maybe front end - memory isn’t what it used to be). I’d guess that was your TZ. Getting passed on the front straight by that TZ750 (I was on an RZ) remains one of my racing highlights.
I sold him my attempt at Honda CR500 engine chassis when I was affiliated in WERA in the late 80s. He is nice man. Do not remember how it turned out probably in a junk pile.
Still have a tz 4dl 125r in the shed thinking about sticking a 350 rd engine in her the 80s and 90s where a special time for the two strokes shame their days ended but two European companies are producing 500cc two strokes shame they are 30 plus grand but do they sing ❤
09:12 Does the Tularis 800 not have an air filter??? The tyre would throw in litlle stones and debris and ruin the engine in no time this way or am I missing something?
@@EbonyPope- 7:41 note the “chin fairing” that covers the carb inlets. 8:10 it looks like it got a full lower fairing.
Raced with that man in 1989 90s. Glad to have meet him
Wow! On which of those he was? What race it was?
An 800cc two-stroke engine in a motorcycle is positively demonic.
I can't even begin to imagine what riding such a machine would be like.
Truly a work of (diabolical) art.
Awesome
i not only envy these geniuses but also remorse on the condition of market where companies don't produce innovations for public....
In racing you rely on sponsorships.
In a public market you rely on the wallet of the customer.
They obviously need to make money and research adn development for one off projects can skyrocket pretty quickly. If you have a big wallet you could've jumped on bikes like the Suter MMX500 where Suter made a 570cc 2-stroke racebike with 195hp and electronic injection.
That's a pretty different thing compared to most of what you can buy.
I am often quite jealous of people who have had an easy start in life and thus seem to have been preprogrammed for succes. This guy seems to have made the best of it all and is deserving of his succes. What a guy!
It's the coolest bike I've ever seen.
Clever stuff! Similar concept to the KÖNIG 500 GP built by New Zealander Kim Newcombe in his garage. The bike used a marine outboard engine and put up a good fight against the big boys in GP racing back in the 70's.
I have an episode about Kim, subscribe🤝
@@wierdbike nice 😊
I will download that as soon as possible☺️
the koning was way more powerfull , the polaris engine isnt a powerfull two stroke is too big on cyl capicity
Yup, I had an old Konig 1950's 250cc racing outboard... About 60 hp, the 500cc opposed 4 cylinder with 'trumpeting' expansion chambers was a real bomb. The 1950's... 🤔
I met Rob about 20 years ago when I was working at Professional Instruments company (Hopkins MN). Another guy I worked with was helping him build the bike in Robs basement.
I remember seeing this in a motorcycle magazine decades ago. It was cool then and even cooler now! Genius!
Cycle world? Great piece on the man and machine. Good to see them remembered.
@@BastardX13 I read it there and I want to say I saw articles in engineering magazines. Seemed it was everywhere I was looking in the late 90's. Then it disappeared and I couldn't find any info on it for years until one odd riding video. I'm glad this one was made to fill in the blanks. In the articles it was just a 650 and they were threatening to go bigger if needed, and that turned out to be the case.
Classic Racer magazine also did an article upon it, as their own, tame, international-racer journo & chief-test-rider (Sir) Alan Cathcart, rode it (the rider with the black Arai helmet with visor-sidestripe Union Jack banners) amongst him riding almost every other serious racebike of one sort or another from each team or independent machine offering of the last 60 years.

Never heard of this guy until now.. and am gobsmacked
Man I love 2 strokes and always will. The feel of the powerband is so addictive!
Thank you for the video - i have and sprint race a scooter with 1/2 a 670 rotax skido top end making a 335cc its a ongoing project
Rotax 670 is a great powerplant, use it in my 93 exciter sx snowmobile, even before i ported the 670 it was a lot faster then stock ex 570 engine, top speed vent from 160kmt to 0-160kmt under 8sec and run out of gearing at 200kmt on the wishometer. Make 112-114 mph on gps, gonna change the sprocket and aim for 4-5mph more in topspeed, its not used for racing except some lakeraces with friends, carburators not tuned for max 1/8 or 1/4 mile races before detonation, can pin it 2-3km without any problems. Its a screaming sleeper loocking like a bone stock exciter. Tried to put xcr 800 tripple in it, too much fabrikations so i left that idea after 10min. Love the rotax 670 and i dont like the rotax twin 800-i hate em, my 670 yamaha outrun them and outlast em without blowing up. Rotary valve power for me👍
Thank you for the feed back - We have a new head and expansion box with some cylinder work my friend Steven Holt how as the other 335cc Rotax Lambretta did 105 mph last year at Santa Pod UK we are hopping for more in 2024 @@kenhmful

How have I never heard of this bike before!? Thank you for putting this together. Great video! Amazing stuff!
Your assignment: Write a script with 30% more words than natural, of those extra 30%, 30% have to be inappropriate, inserted in the wrong place in the sentence, or redundant.
I enjoyed it and found it interesting in spite of you satisfying all requirements of the assignment. Well done!
A man named Ted Wilkins built a hill climbing bike out of an old triumph motorcycle and a 540 rotax ski-doo motor and scared all the big boys..# MC Access 1991 devils stair case.....in 1995 he had built a crotch rocket from scratch using a 540 rotax ski-doo motor...carbon fiber and aluminum components..the motor was the frame" he was from Markham Ontario Canada look him up!
Was so glad to see this, specially since it involved Fernando Alonso and Renault
Crazy what 2 strokes can do. Facinating story. So cool to see people with such excellence pour themselves into a project.
The eccentric adjustment looks exactly like the Benelli chain adjuster. It’s a great idea. Wonder which came first? This guy is a visionary and that motorcycle is just a missile! 👍🏻
kawasaki gpz900 (ninja 900 in the usa, I think) had it in mid 80ies. And a lot of Kawa after her, until now.
It's been done before, Ducati 860 GT and it's derivatives had this, Bimotas used an eccentric at the rear axle.
Wow! A true motorcyclist of the finest order.
I remember Rob from his WERA days and what an awesome Norton he had. I remember inside of his van one wall of the van was a peg board with dozens of gears. which after every race he would putting new gears on the Norton between races. And just a real down to earth guy. Really happy to see him to become so successful!
I can't imagine crossing the powerband on that thing! What a frickin' 'rocketship'! 🚀
It is now 2023 and I'm building a bike just like his with a 2019 skidoo 850 summit engine.
Crazy to hear his story. I grew up in this Era at polaris. 21 miles from my house!! I have alot of experience with the engine he put in that bike. But I chose the skidoo 850 because it's alot more advanced than a polaris engine. Debatable sure, but that's my opinion. I like their direction injection more than polaris fuels injection.
That’s super cool! Good luck with the build!
Hey. That’s sweet. Finish it yet?
I saw it at Goodwood but didn’t fully appreciate what I was seeing. Thanks for the video.
An 800cc 2 stroke would have been an absolute handful when it hit it's powerband.
It was great to see the Tul-aris again, I was fortunate to meet Rob when he lived in Minneapolis. I helped out with the Tul-da, on occasion, in the paddock at Brainerd International Raceway in Northern Minnesota (at the time he was collecting data on a new pressurized airbox, handmade in carbon fiber). I also worked at Professional Instruments Company where the transmission plates and other Tul-aris parts were machined by my friend Tim Wirtz. Rob is a great guy, willing to share his knowledge. I still have some of his notes, scribbled in the margins of a local newspaper, on how to improve the geometry of my old cb550 café racer!
09:12 Does the Tularis 800 not have an air filter??? The tyre would throw in litlle stones and debris and ruin the engine in no time this way or am I missing something?
@@EbonyPope it has a carbon fiber airbox.
Edit: at 7:17 you can see the airbox in this photo, this shot is on a poster that Rob had made when the motorcycle was first raced. I still have my copy hanging on the wall in my garage! You can also see the minimalist frame with the plates that hold the transmission. The swingarm is a work of art, very long for the time. He was showing it off like a proud father at the coffee shop we all hung out at. I remember him telling me about the benefits of maximizing the swingarm length and his dismay at the extremely short one on a Buell Lighting that was parked nearby.
@@jfu5222 Oh I see it now. But does it contain any filters? Or are the carburators completely open just protected from debris by the airbox?
@@EbonyPope I can't be certain, but probably not. Race tracks are reasonably clean and free flowing air is a priority.
I was there that weekend and went up just to check out this bike after seeing it in Road Racing World magazine. Very cool indeed.
this bike was amazing I remember watching his progress . nothing like a two stroke
I had almost forgotten about this bike. A bit of a stretch to say built in his basement, assembled is what I would say. The bike was so cool to see back then and many hoped that Polaris would start building them. The bike would still be competitive today de stroked/bored to meet 750cc class. With how good the teck he was using back then it's even better now, the transmission could be geared much better than off the shelf Ducati parts. I spent 2 hour's in person drooling over this bike as a 18yr old kid., wondering how he came up with every detail of the bike. Bikes that had eccentric chain adjusters alone made no scene to me, as the rake of the bike changes with each adjustment, the swing arm pivot has to change at the same time, he solved that. He set the bar quite a bit higher and everyone noticed bikes got much better quickly because of him and his 1 off bikes. I could wright a book about all the things he did that slowly came to be on many bikes, how motors got forward leaning cylinders to keep thrust angles more in line . He was crazy smart wonder if he is still alive?
I was very lucky to see this bike on the track. They would run some asra and ccs races. We all knew it was a special bike back then.
What a machine! What an engineer! No wonder he ended up in an F1 team. And If I' read the comments of the people who met Rob, he must be a nice guy aswell.
Vlad, I like your videos and your accent doesn't bother at all.
It would great to have a street legal version of those bikes. I purchased a Yamaha RZ500 new in 1985 and still have it. It's in near mint condition.
Channeling his Inner Jon Brtten...........................................
Very cool!
Very smart guy and an awesome creation!
This is pure motivation for me.
I would love to ride this bike such a masterpiece work of art that can fly and corner like nothing I’ve ever seen
The telescopic fork has an axle and two aluminium tubes as unsprung weight, the usd fork has an axle and two steel pistins as unsprung weight.
The usd fork has greater rigidity which is why it is used these days but the unsprung weight of the telescopic fork is hard to beat.
Find out about Kim Newcombe. The Kiwi who put a Konig outboard motor in his own frame. Was leading world 500cc championship until he was killed back in 1973.
I have an episode about Kim, subscribe😉
For pure power nothing beats a 2 stroke.
Reminds me of The Britten.
Always thought a two stroke jet ski engine would be cool if the coolig system was sorted
Very cool episode, thanks for sharing this with us !!
Thanks for watching🤝
Very cool.
Been done in the 70’s though.
Go back 50 years earlier
Look up
Kim Newcombe
Built his own race bike ,winning GP's on a Koenig powered self built race bike
No computers no engineering degree
1950's slide rule pen and paper
Maybe a good idea for a future show
Also John Britten (who needs no introduction)
Both self taught New Zealand constructors and racers
This can be done again, 2 strokes are unmatched in power to weight. Currently, i doubt youd even be allowed to enter a race series with a 2 stroke. if they werent shunned so completely by governments and manufacturers, im confident a genius of today could build something similar if he had the desire.
Awesome guy, awesome bike. Thinking out of the box may create wonders. And the sound.....
That means he helped design my Victory Sport Cruiser , I had another guy on the original design team stage 4 my motor , 112 Hp , 118 ftlbs of torque , on the dyno
Great video, looks challenging track. Great you guys made it ok 👍
The rear suspension setup is sweet.
When star trek meets two stroke “ I canny give it full power captain, it keeps lifting “ ha ha ha
Wow! Great bike man! However - when you say “he built it in his garage,” you might want to add that his particular garage is more equipped and high- tech than most race teams!
Love this video 😅 and all others that display injinuity over all out expenditure😅
Robin has similar background with Erik Buell
Back in the late '80s/ early '90s, there were a couple of guys brought a snowmobile powered bike up to Sportbike Rally in Parry Sound, Ontario. Fast and light, but they retained the CVT tranny, and couldn't get it to work well for a motorcycle application.
SLP built my 700 Liberty snowmobile motor , 150 plus hp on 91 octane , so I’m sure a big bore 800 performance edition motor on race fuel would be close 190 hp , PSI used to built 190 hp twins from liberty motors
Who makes that remote transmission? Awesome work
Brutal Power band
i love this guys accent
Well done Dr,,i want one ,,,,,yesterday,, cooles thing ever
Do Motus motorcycles next! This is a great series!
Great video thanks. Interestingly, John Britten also played around with unusual engines in bikes, he put a Konig 500cc outboard motor in (I think) either a Triumph or Norton frame.
Sure you're not thinking about Kim Newcombe?
@@SB-Kiwi Yeah, nah, I might be wrong about the engine make. After a bit more thinking I think John might have used an Evinrude or West Bend motor in his bike, apparently he really liked the design of the engine.
@@onecookieboy I wouldn't be surprised. The man was always thinking outside the box alright.
ha, for some reason i always thought the Tul-aris was a CVT driven bike, turns out it does have gears. I guess predictability is good thing when that thing gets in the powerband
Snowmobile engines are no friggin joke. Anyone who has ridden a high performance two stroke snowmobile knows that. They don't use power valves as they aren't needed in a snowmobile with a CVT.
It must be like getting rear ended by a bus when that 800 gets on the pipe with some good throttle behind it. With no modern electronics and that sharp power hit, that bike sounds like a potential highside into orbit. Rider beware, throttle control and respect are obviously required 😆
Epic bike. Amazing what can be made when everything isn't ran by the gov with regulation.
I'm subscribed. Good work on photo/video collection and reasearch presentation man! You're English is great don't worry about taking more lessons and stay safe in hard times. Keep up the work!
Thank you so much🤝
All of that dialogue and no audio track of it wound out on a track, what were you thinking ?
what a beast
3:57 Frame reminds me of an SE Quad-angle BMX frame.
That's actually a great idea! I'm really surprised people haven't done this more since
Concept of this bike looks really uncompromising - simply fantastic. The gearbox housing side panels seem to be the most massive parts of the whole bike. In my eyes this bike is no beauty - but of course this doesn't matter. 🤓
That's a beautiful bike no matter which way you look at it... a true work of art
I remember talking to him at Daytona one year and he mentioned the Carbon Fibre gear case. He probably cooked the carbon in his kitchen oven. Amazing guy. We used to set him up with seemingly sencere questions about atomic structure, or austral physics and he would just go off for hours. We had no idea what he was talking about. He never knew…
Gearbox internals were Ducati….
@@suzukiyesteryear
I gather you don’t feel ashamed at having wasted his time?
@@russelldawkins9094 Quite the contrary, it did not matter which of my bikes he road: 250,350,750 he was a mad man on anything two-stroke.
He either crashed or won. He was uncompromising. Watching him fling the big TZ750 around was amazing…
I'm surprised it doesn't overheat.
Love all you ol school og pioneer badasses. Don't & won't make'em like that anymore
Leave a rocket scientist alone for a bit...
I remember the tularis back in the day, really hoped he'd make em for sale or a kit.
Mike Ciccotto told me the bar grips vibrated so friggen bad on this bike it took all he could to keep his grip on them. It would buz your hands right off Mike quoted. Does anyone know how to reach Mike Ciccotto?
Seems like a clever and practical chap. He started an AI company which makes CAE simulation work faster and more efficient. Sounds like a more society-useful application of AI than (say) annoying chatbots.
I want to know if Alonzo ever rode this bike/weapon?😅
Well done! Your effort is excellent for someone whose first language is, I am sure, not English...😇
Great video. You gained a south african subscriber 😊
Thank’s🤝
I F'Kin LOVE that Bike.!!
Thanks Mate..
🤝🤝🤝
12:09 on ptw yes its still at the very best but what this doesnt show is usability. Thats where bikes (and cars) have really come on. I race 2 strokes & have 5 of them but a 4 stroke is far easier when its big power like this to put down
Haha, that picture of Robert Jenson is actually Dan Bilinsky.
SUBBED
I still think the Britten is the better all round bike. Britten looks better and every thing was made from the ground up including the motor. All this done with out computer technology as well. in saying this the TUL-ARIS is still a fine bit of engineering.
would have loved to see some onboard footage!
I wish I had been there to see/hear his bike at Cadwell Park @ 9:57
We hat motor is it running? Square 4 or v4
44 Em em? You mean millimeter?
You all miss the most important point! This designer can think outside the corporate box. Very rare these days . I wonder how he would do at designing areal sensible 500 cc adventure bike ? NO one has managed to do that yet.-- - - - Herb
if you allow an extra 150cc, the DR650 is the perfect adventure bike, with a bit of fettling...
To be fair, the NSR 500 V was, as the name suggest, 500 cc.
A beautiful machine nonetheless.
Your script, or grammar, leaves a lot to be desired. But I do appreciate the video.
FYI, i watched a vid with the Ducati superleggera dyno to the real wheel 195hp and weighed 400lbs / 181.4 kg's
They are known for exaggerating these numbers. This would very much validate your video showing this bike actually does posses a greater power to weight ratio.
wow i wish my company would let me build a superbike using all their equipment lol
How has the narrator managed to have a slight French accent with a posh English undertone.
Great information, great video 👍
..Canadian Quebecois perhaps...?
@razor1uk610 maybe? Just twigged me ear and I couldn't figure it lol.
from the "about" page, ...... "My name is Vlad, I am from Ukraine", and he says above, that IS his voice
@alunchisholm481 now thats a curveball 🤣
Sounds like AI narration to me.
He was fed up believing in space and fairies and shit then he decided to go do something thats routed in reality 😂 Well done..! 👏
These snowmobile 2 strokes use Direct Injection. That is why they can achive TWICE the power of 4t of the same displacement and with low emissions!! But motorcycle factories have persistently ignored them..
Two cycles can make big power without direct injection as well. The direct injection is to help them burn cleaner. The manufacturers don't make road bikes with two cycle engines Because the emissions standards are tough for 2 cycles to meet. But 2 cycles are the predominant engines of choice for snowmobiles because of their high power to weight ratio and CVT drivetrain.
It pretty much takes a 1,000 cc 4 cycle to match the power of a 600cc two cycle and then they are way to heavy for a snowmobile. That and 4 strokers cost more.
It does not appear this bike uses DI, ......as it's very obviously carburated !
you want power? get a 2 stroke.
then people want to battle that statement and then come up with arguments about diesels and crap...
they should rebuild that thing again today with also carbon stuff just like that ducati, lets see how far they can get the weight down even more.
Totally agree.
It's really odd how your accent drifts in and out of an English/kiwi accent, then into an Indian one and then occasionally into an American accent, truly bizarre. I like the content though
only 7.5L of fuel... on an 800cc 2 stroke... thats opening the throttle twice, and you are on your way to the petrol station...
Disappointed to not hear it run and accelerate more.
It's pronounced Tu-Lu-E!
Did he race with CRA @ Brainerd International Raceway (BIR) In late 80's in Minnesota?
I believe he did
Yes, I believe Steve Johnson was the rider.
