By far this is one of the best engineering projects on RUclips, if you followed the videos on its build you will know Malcolm is a true craftsman and the bike contains many innovations with regard to how it was made, all in all a stunning bike. There is no mistaking that induction roar, if you know your outboards!!
Since the exhaust ports all impinge on that exhaust cooling blade that he showed at the beginning of the video, there's no possibility of attaching 6 expansion chambers to this engine. But you're right, it would sound glorious bellowing out of 6 exhaust stingers.
I am 68, and started out in the glorious 2-stroke era. This is wonderful. To hear and see this machine in the flesh would be quite an experience ! Congratulations on a job excellently done ! Trinidad & Tobago. West Indies.
My first motorcycle ride was a 1966 Suzuki 100 my brother bought with Paper Route money. He never plated it and rode it on the road, he used it as a Trail Bike. There were none at the time, they hadn't even invented the Scrambler yet (on road bikes converted to off road with High exhaust pipes and more aggressive tread tires). So they would take the front fender off due to mud buildup and they took the muffler off because it would bottom out. I rode it through our back yard. A couple of years ago I bought a Suzuki TC100 just so I could hear the motor and smell the smoke and relive a little of the past.
@@fukhue8226 A similar story with me in 1965, my first bike was a 1965 BSA Super Bantam 175cc two-stroke, it was not my first choice at the time, I had visited Kings Motorcycles before in Leeds, Yorkshire and picked out a second-hand 1961 Royal Enfield Crusader 250cc, but needed my dad's signature to purchase it as I was under 16 years old, unfortunately, when my dad came to see the 250cc Crusader he said it's too big for you, we'll look somewhere else, so then we went to a BSA dealership and dad said that's more your size, I said, dad that's a 175cc Bantam, in an embarrassed tone, he said it's that one or nothing, so I settled for the 175cc it was definitely better than nothing! 👍😊
I have an old formula V (VW) chassis buried in my garage and a tool shed full of 40hp outboard motors. Rather than rebuild a really old vw motor I’ve been inspired to get one of those 40hp, 2 cylinder, 2 cycle, water cooled motors mated up to the vw trans, clutch and flywheel. I’m 76 and everyone is trying to take the fun out of life by selling off anything I have that moves. I started this journey at the age of 14 with a 1.5 hp Briggs and Stratton motor hooked to a bicycle using angle iron from a for sale sign across the street and about 6 coffee cans full of nuts and bolts that my dad had collected. It took me a while to the gear reduction right but finally did and had a blast. No brakes, a frame with the stiffness of a wet noodle and 1/2” vee belts and the biggest vee belt pulley Sears catalog had, a 12” then through a Jack shaft. Top speed was close to 25mph. I had a custom 1/2” galvanized steel pipe exhaust, straight through, no muffler. Ram air induction ( at 25 mph with me sitting in front of the motor I doubt if there was much ramming going on. It was fun then, it will be fun this summer. Not quite as impressive as 48 cylinders but we all have our limitations.
Listening to Mercury 2 strokes has always been one of the sweetest sounds in the world to me. My Dad used to work on and at times race them and to me there is nothing quiet like the sound of a straight 6 “tower of power” Mark 75 or Mark 78 growling behind the boat. Those engines had soul! To me, they have always seemed like living, breathing beasts. Thanks Dad. And thanks to the builder of this magnificent 2 wheeled wonder. You sir, are amazingly talented.
Thats because they were beasts ! No, but I definitely feel you about those old straight six mercs, there is just something about the way they deliver their power that makes them so awesome !
I have a Mark 75 powerhead, and have had the idea for 5-6 years, to make an across-frame motorcycle engine from it. Surely not so powerful, but the sound would be lovely.
I started racing 🏁 boats when I was 12 years old. My grandfather was the east coast dealer for a pontoon and deckboat company, and he stuck me in a 14' kneeler pickle-fork hydro with a big black and chrome I6 on alcohol with a couple drops of nitromethane just for good measure!...lol my uncle Dick was the engine builder and tuner. My gramps was in tight with the Kiekhaefer family. Some big wigs would come and visit our lake property, and we would try different propellers, gear cases, powerhead's, and stuff like that. We weren't lake X type parts, but we were close!..lol Our factory 150hp was around 290-325hp, depending on altitude and air quality! The strongest crank ever! The adults did everything but pilot the boat, that was my only responsibility, don't crash the boat, was mine!..lol...from Wyoming USA 🇺🇸 👋🤠
@@billallen4793ive never seen a strait 6 merc produce much over 200hp. its a crossflow for heavens sake! thermal loads are tremendous. hell a 2.5 merc needs a re-ring every 20 hours in its factory 280hp guise
Very cool machine you have created! Sidecar racer Eric Parkinson fabbed a Crescent Marine racing engine, a 500cc two-stroke triple into his sidecar. It managed about 85 mph average at the TT in 67'. He endlessly chased overheating issues & later discovered the water jackets around the cylinder were intentionally designed to be small because the engine was intended to only ingested fresh water from beneath the vessel.
I can't imagine how satisfying it must be to finish such a cool project. The bike is amazing, the videos are interesting and informative. Well done all round and thanks for sharing. Rubber side down!
Unmistakably Mercury! Having owned Mercury powered boats for years, the sound was instantly recognisable. That's the best sounding 2-stroke bike I have ever heard.
Amazing accomplishment Malcolm! I did the original design of this engine some 50 years ago never thought in my wildest dreams it would ever see use on a motorcycle. Love that sound!
Outboards are normally measured in GPH(gallons per hour). The rough benchmark a few years ago was 10% of the horsepower is the GPH. A 50hp outboard will drink 5 gallons an hour, at a good throttle setting :)
Thank goodness you’re back. I was missing your channel. Stuck in a rut at the moment after losing my workshop during Covid so instead of designing and building things myself I am reduced to watching others. Hopefully once the big tour, round the world in 100days, is over I can get back to building RoToR race cars for fun. Heading for Sydney today strangely and hoping to catch up with Elwyn Bickley. Keep up the good work.
I clicked because I wanted to see how you adapted a marine engine to a motorcycle. Putting the power to the rear wheel, cooling system all the demand engineering, let’s go!
this is incredible! i loved the sound of that motor ever since i was a kid. black outboard motors with orange and yellow stripes were everything back in the day.
It's a very satisfying feeling, building a special from the ground up, being the test pilot, and finding out that it all works ! I've built a couple of VW aircooled bikes, using the car transaxle modified to foot change and hand clutch. First one was a hard tail chopper, with a double cradle frame and my latest one is a box section spine frame with Z1300 forks (beefed up) and rear shocks for a Rocket 3. See VW bike for 7 foot rider, under Celia Ketley (my beloved wife who passed away nearly three years ago). I'm Daryl.
Sir, it is just delightful to see you back with this unique beauty. Last I saw, you'd basically put 'er all together, unregistered, and no paint yet. You gifted us with a brief sample of the explosive cacophony of metallic chaos* that the 2-stroke V6 releases upon starting. I believe I left a comment attempting to somehow evoke the sound, and no doubt fell short... (A brief interlude) Now, here's a proper Motorcycle! Look at that lovely beast! It's...huge! Well, you won't have any shortage of power. I really like that there's no an attempt to fit into any currently established genre like "cruiser" of "sportbike" or "adventure tourer". Its just a very generously proportioned "draw-a-picture-of-a- motorcycle" motorcycle. With a gloriously batsh*t engine. Speaking of which, it sounds really nice, especially when the revs climb and it starts to smooth out. I have to admit I'll agree with some of the other comments urging you to put some expansion chambers on it, but designing and fabricating 6 big chambers and making them fit would be a major project! Awesome bike, thanks for showing it to us. Keep us in the loop, and stay safe!
Well done, I can recall watching Kim Newcombe riding his Konig powered "outboard" engine in the early 70s just prior to his tragic crash at Siverstone.
What a fantastic sounding ride! I can't imagine the amount of work and skills needed to achieve such a masterpiece of engineering. I have to check the building videos. Thank you YT algorithms! It's not everyday...
Wow. This just turned up in my feed. What a fantastic idea. Never seen anything like it, but I love it. And now I have to watch all the build videos too.
In 1979 my auto shop teacher brought in the engine blocj from his outboard motor. I can't remember what HP it was, but we all looked at that lightweight & high power motor and had ideas like "go kart motor!" and "add two cylinders & scale up that 2-stroke to big-block chevy size". A 7.5L two stroke would be amazing!
Very cool build. I wish I had more info and I wish you would have shown a photo of the engine sitting in the bike as well as giving it a good scream run so we could see how it responds and sounds. Pretty amazing build
Very cool indeed. Years ago a guy here in NZ put a Johnson outboard in a speedway midget. And don't forget Kim Newcomb A Kiwi who built a race bike with a Konig outboard (from deepest darkest Europe) he worked for them to and was quite successful with it back in the 70's. He crashed and died like a lot of them did back in the day. Saw a really good doco on him some time ago, it's probably here on YT somewhere.
Great idea, ive put a merc v6 in a snowmobile. Like the bike, but that big v6 needs to breath more on the exhaust. Those two tiny holes are not enough!. You should see the stock tuner the factory puts on that engine, its a megaphone for both banks..
Brilliant ambition meets brilliant craftsmanship! I'd like to see three things - a fairing, tall gearing and some space to let it stretch its legs and show the true potential!
Interesting.....I recall a friend of a friend back in the late sixties who was building a drag bikw with a 4 cylinder inboard boat motor into an old Sumbeam chassis.
There should be a big warning sign in videos where people drive on the left side of the road. I was like "Oh my God" at 4:16 where you were driving on the "wrong" side of the road and suddenly I saw a pair of lights coming at you! 🙂
Owned a 6 m tinny with a 2.5 merc 150 hp efi . It did not climb onto the plane it just leapt out of the water . Party trick was to drop the throttle and make passengers not holding on fall out the back . That's a low power version of the engines potential. In a bike it would be scary to say the least .
Thats absolutely beautiful, a work of art bro, I want one more than anything else, I love 2stroke and Mercury are my favorite boat motors, that gearbox doesn't know what hit it lol, certainly not a V twin 4stroke engine. It actually sounds slightly like a 4stroke with the V6 growling giving it a cross plane crankshaft effect, I really need to show my mad mechanic brother this, and hopefully I can find from start to finish, thank you awesomely for sharing your great experiments and experiences.
Great! Subscribed. Now I have a reason to watch all your videos about this bike from the last 3 years. I don't see a playlist. That would make it a lot easier to watch all of them. Maybe you can create one.
Wow, mate, great effort! RUclips knows I like motorcycles, engineering etc, but I wasn't expecting a 2.5L V6 two-stroke in one of my all-time favourite bikes! I'll bet you need those anti-dive forks...
What they said my dream has been to do the same project after having a boat shop in the late 80s early 90s I got to work on the Black Max two-stroke v6s along with all the other cool outboards. I've owned and restored many 10s of 2stroke bikes and I will build a crazy one one someday. This is ear porn
I don't take much notice of the latest wizzy bike as most seem to be just a re-hash of the last one, homemade engineering I am totally on board with this .how many of us have looked at an engine and wondered if it would fit in a bike frame 👍
What a fantastic achievement, congratulations, sounds the business too. Watched a vid on RUclips recently featuring Kim Newcombe, who no doubt you've heard of..
It is mission impossible here in NSW Fact !, no Approved Engineer would take the task on of Compliance Testing, the RMS has made the task impossible so as to keep one off's and modified vehicles off the road. Conclusion = keep the RUclips fans hooked with smoke and mirrors. NSW Rego 100% no way, Impossible !! Sorry Malcolm but I am calling you out on this one.
@@gasdive Its not possible, its classed as an ICV "individually constructed vehicle", I questioned Malcolm on this and he replied its Registered as a 1985 Model. ICV's can only be Registered as a current model 2024 requiring Compliance with all applicable 2024 Design Rules, All rules "ADR's" require testing for Compliance by an approved Engineer. a 1985 Suzuki does not have an outboard motor and a standard GSX does not have a modified frame, so its not a Suzuki, its an ICV. I put this to Malcolm and received no reply to date.
@@mohuckmedshishkeblob1712 I didn't notice your reply until today. Yes, I suspect you're right. It might be a 1985 Suzuki on paper, and be fine as long as no one in a uniform ever looked at it, but riding on the road would be skating on very thin ice.
Wow! I've been toying with the idea for over a decade of putting a 2.5 EFI in a Miata. The basic idea is an inverted V setup. I have all kinds of ideas about how to handle the cooling and lubrication systems. Yours has a lot of gear noise, so I'm guessing you have some kind of large module geared primary going on? Can't wait to binge your channel and see all the answers there :-D
Ever since I saw a v6 2 stroke outboard in full cry I desperately wanted to get hold of one and stick it in a bike frame. They never seem to come up for sale....
Sounds beautiful and beautifully engineered. I would have preferred a more retro headlight and gauge cluster. Something more along the lines of a Suzuki gt750 and carrying that theme of a big comfortable two stroke grand tourer with plenty of storage and luxuries to make touring Australia bliss.
In America on the triple cyl snow sleds they have a kit to put triple pipes and what they call stinger mufflers and being half a 6 they sound similar in sound, thinking they would sound beautiful! It sounds so good it makes the hair on your arms stand up! LOL
You sir, are a nutter! Keep up the good work! 👍 My first 3 road bikes in the late 80s were 2-stroke 250s so I have fond memories of those smokey temperamental beasts. Have you ever seen the 5 litre V-twin built by “Lucky” Keiser in NSW(Dubbo, if my long fading memory serves)? Two cylinders cut off the end of a WWII Rolls Royce Merlin V-12 aircraft engine which had powered a Mosquito bomber…
@@malcolmoastler3039 you are correct! The smell, the highly strung temperament, and in the day the 500cc GP 2-stroke bikes! I could very easily hand start my ‘89 RGV250’s kickstarter because of the low compression, but it was still a rocket ship! A smoke-belching(if I set the mixture too rich - just once!), thirsty, inefficient rocket ship! The RGV however was not considered highly strung in those days for 2-stoke bikes… my earlier air cooled ‘77 RD250 however… 2-strokes will forever have a place in my heart!
Cool bike, but watching you ride on the left side of the road gives me the Willies ,keep thinking about a head on crash lol. Cheers from British Columbia Canada
Occasionally RUclips algorithm directs you to something interesting, amazing bike in every way and made in Australia is the icing on the cake.

That's a low power version of the engines potential.
In a bike it would be scary to say the least .
Thats absolutely beautiful, a work of art bro, I want one more than anything else, I love 2stroke and Mercury are my favorite boat motors, that gearbox doesn't know what hit it lol, certainly not a V twin 4stroke engine. It actually sounds slightly like a 4stroke with the V6 growling giving it a cross plane crankshaft effect, I really need to show my mad mechanic brother this, and hopefully I can find from start to finish, thank you awesomely for sharing your great experiments and experiences.
Damn what a piece of work. I'll be sure to check out your vids on building this GSX
I'm glad to see it finished and on the road, nice work.
That engine note sounds amazing and could become quite addictive I'd imagine 👍
200HP? Would be interesting seeing some dyno figures, what a crazy and awesome build!👌🏻
What a brilliant sound it makes. And well done all round.
I can't help but wonder about how sweet that would sound with six expansion pipes!
Great! Subscribed. Now I have a reason to watch all your videos about this bike from the last 3 years. I don't see a playlist. That would make it a lot easier to watch all of them. Maybe you can create one.
just go to my channel. they're all in chronological order
Amazing project. I hope Millyard sees this build
Wow, mate, great effort! RUclips knows I like motorcycles, engineering etc, but I wasn't expecting a 2.5L V6 two-stroke in one of my all-time favourite bikes! I'll bet you need those anti-dive forks...
Awesome project completed to the highest standard. Congratulations!
The coolest thing in a long time on RUclips
Astonishing ! What a neat ride. Thanks for showing us.
What they said my dream has been to do the same project after having a boat shop in the late 80s early 90s I got to work on the Black Max two-stroke v6s along with all the other cool outboards. I've owned and restored many 10s of 2stroke bikes and I will build a crazy one one someday. This is ear porn
Thanks for sharing what u built! Ive often wondered if an outboard could be used to power a different vehicle. Now I know it can and very well. 👍🏻
id love to see this things absolute top speed ... nice work and clearly capable
Stunning work! Jim Goose gives the nod.
outboard motorcycle ? Nice of you to follow in Kim Newcombe footsteps
I don't take much notice of the latest wizzy bike as most seem to be just a re-hash of the last one, homemade engineering I am totally on board with this .how many of us have looked at an engine and wondered if it would fit in a bike frame 👍
brother i thought it was electric its so darn quiet and smooth wow! sweet bike !
What a fantastic achievement, congratulations, sounds the business too.
Watched a vid on RUclips recently featuring Kim Newcombe, who no doubt you've heard of..
the other Bert Monroe. Should be a full length film tbh. A great story. 2 strokes rule!
Hell yeah man, been looking forward to this video. Looks like it pulls like a freight train. Good job man, that motorcycle is an engineering marvel.
freaking legend im so glad youtube recommended this to me.
Beautifully crafted and sounds great.
Great Build! Unfortunatly where i am living this would be almost a mission impossible to registrate it and drive it legal on the streets…
I have no idea how he managed it here. If I hadn't seen it done I would have said it wasn't possible.
It is mission impossible here in NSW Fact !, no Approved Engineer would take the task on of Compliance Testing, the RMS has made the task impossible so as to keep one off's and modified vehicles off the road. Conclusion = keep the RUclips fans hooked with smoke and mirrors. NSW Rego 100% no way, Impossible !! Sorry Malcolm but I am calling you out on this one.
@@gasdive Its not possible, its classed as an ICV "individually constructed vehicle", I questioned Malcolm on this and he replied its Registered as a 1985 Model. ICV's can only be Registered as a current model 2024 requiring Compliance with all applicable 2024 Design Rules, All rules "ADR's" require testing for Compliance by an approved Engineer. a 1985 Suzuki does not have an outboard motor and a standard GSX does not have a modified frame, so its not a Suzuki, its an ICV. I put this to Malcolm and received no reply to date.
@@mohuckmedshishkeblob1712 I didn't notice your reply until today.
Yes, I suspect you're right. It might be a 1985 Suzuki on paper, and be fine as long as no one in a uniform ever looked at it, but riding on the road would be skating on very thin ice.
Wow! I've been toying with the idea for over a decade of putting a 2.5 EFI in a Miata. The basic idea is an inverted V setup. I have all kinds of ideas about how to handle the cooling and lubrication systems. Yours has a lot of gear noise, so I'm guessing you have some kind of large module geared primary going on? Can't wait to binge your channel and see all the answers there :-D
That's a well engineered conglomeration you built there mate.
Totally awesome. Love it! My new favourite RUclips motorcycle.
Sounds wicked very cool bike great craftsmanship man
Beautiful bike and awesome engineering,well done Malcolm 👏🏻👏🏻👍👍
Fantastic idea !. Hope the brakes are over dimensioned !.
Ever since I saw a v6 2 stroke outboard in full cry I desperately wanted to get hold of one and stick it in a bike frame. They never seem to come up for sale....
Sounds beautiful and beautifully engineered. I would have preferred a more retro headlight and gauge cluster. Something more along the lines of a Suzuki gt750 and carrying that theme of a big comfortable two stroke grand tourer with plenty of storage and luxuries to make touring Australia bliss.
yes, a round headlight and a mini fairing to cover the instrument pod, definitely
New here and impressed with the customization/engineering 👍🏼
Idle hands do the devils work, not always, sometimes they create innovate and invent. Top Job.
I've always wondered if you could do this! So cool!
In America on the triple cyl snow sleds they have a kit to put triple pipes and what they call stinger mufflers and being half a 6 they sound similar in sound, thinking they would sound beautiful! It sounds so good it makes the hair on your arms stand up! LOL
Nice, I wonder what Carl Kiekhaefer ( founder of Mercury outboards) would make of this !
You sir, are a nutter! Keep up the good work! 👍
My first 3 road bikes in the late 80s were 2-stroke 250s so I have fond memories of those smokey temperamental beasts.
Have you ever seen the 5 litre V-twin built by “Lucky” Keiser in NSW(Dubbo, if my long fading memory serves)? Two cylinders cut off the end of a WWII Rolls Royce Merlin V-12 aircraft engine which had powered a Mosquito bomber…
yes, but everyone with a soul loves a 2 stroke
@@malcolmoastler3039 you are correct! The smell, the highly strung temperament, and in the day the 500cc GP 2-stroke bikes!
I could very easily hand start my ‘89 RGV250’s kickstarter because of the low compression, but it was still a rocket ship! A smoke-belching(if I set the mixture too rich - just once!), thirsty, inefficient rocket ship! The RGV however was not considered highly strung in those days for 2-stoke bikes… my earlier air cooled ‘77 RD250 however…
2-strokes will forever have a place in my heart!
Sounds insane man wowowowwyou did something amazing
Cool bike, but watching you ride on the left side of the road gives me the Willies ,keep thinking about a head on crash lol. Cheers from British Columbia Canada
That is awesome. It would have been a very interesting project to work on.
Sounds absolutely LOVELY! :)
