The Best of Single-cylinder SuperBikes!

[@karlvanboxel561]

Ducati supermono is streets ahead imo with its counter weight directly in the crank pin where it’s most effective combined with w/c and Desmo Its a masterpiece of engineering

[@Buddhamaniac]

great bike. Yamaha built a limited production street-legal bike in the mid 1980s called the SZR660. 5 valve, dual carb, modified TD2 frame, light and fast.

[@COIcultist]

The engine from that was used in the MZ Scorpion, Mastiff and Baghira.

[@Buddhamaniac]

@@COIcultist yes, you're right. good bikes all.

[@dr.jiIIaIicecooper2587]

@@Buddhamaniac 90s not 80s I remember that bike from the time I was a kid. It thought it was futuristic and cool looking bike back then. Still looks good

[@Subaruktm]

Ok guys the Engine was minarelli built And the frame was tzr belgarda

[@grooviefan]

@@Subaruktm have any proof that the engine was built by minerelli ?? Never seen it in print in magazines . Hard to believe yamaha would farm out an engine when they could do it inhouse

[@markbarber7839]

Thanks for the video. A few items I didn't know until now!

[@murraybates9266]

AJS had a triple overhead cam 350 single in 1954 the 7R3A it had three valves per cylinder with a chain driven cam driving the intake valve and a bevel geared cross shaft running two exhaust cams.

Amazing

[@JOOLZNED]

Lovely bikes, the Ducati is great but too expensive. Built my own single cylinder bike 300 lbs ( 140kg ) 80hp 56 lbft torque total cost £5000 and its great fun

I’ve been thinking about making my Honda 650 into a race machine just need to take it apart and add some tuning goodies like the pulse generator rotor needs to be welded to add material and then ground down to have sharp edges for the pickup. That increases timing with a new cdi so I can have higher ignition timing and use alcohol or maybe race fuel. Up to 40 degrees of timing supposedly. Did you ever have to go with a separate ignition system to reach that power level.

[@orgillmathew]

Love a good single

[@1622yamaha]

I believe I saw this bike race at Sears Pt. way back when, smoked the battle of the twins race, looked like it would've been competitive in the superbikes!! Me and my bro were sayin' noway that's a single!! haha. By the sound of it, and now seeing it kinda is not a single, lol. Awesome bike, awesome sound

[@paulscountry456]

Stunning ,that rpm from a single,pneumatic valve actuation will be common soon .

[@fidelcatsro6948]

yes indeed pneumatic valve is a seriously good new cat design on the block..eliminates a lot of metal rotation parts

[@paulscountry456]

@Alfred Wedmore you are wrong ,pneumatic has been used for years in moto Gp and F1,that old desmo actuation cannot compete as the valves will float ,do some research and educate yourself.

[@paulscountry456]

@@fidelcatsro6948 yes of course it is superior and has been in use for years on moto gp and F1 that complicated desmo design is still used by Ducati but is inefficient in comparison, try telling that to a Ducati snob...lol.Ducati has not dominated moto gp in 15 year or more.

[@fidelcatsro6948]

@Alfred Wedmore nothing beaten poppet valves? my 2 stroke yamaha with reed valves disagrees🤪👍🏿

[@joshuarenacia694]

@@paulscountry456 lol you're so funny🤣. Then why does Ducati have the highest power rating in their MotoGP engine? Because it revs high due to the elimination of valve floating.

[@fidelcatsro6948]

desmosedici valvespringless design is ingenius, even my oxford educated cat 🐱 never thought about it..

[@dr.jiIIaIicecooper2587]

You can't think of everything

[@johncunningham4820]

The 5 valve Engine I thought had horribly Shrouded valves until I took a closer look . Not at all . Very high compression I would think . Both bikes are works of Engineering Art .

[@Danger_mouse]

So they took the regular V twin, left the stock V crank and block alone and gave the now spare connecting rod a link to hold onto so they could save making new parts from scratch. Would have saved a lot of development time and money. No so sure about the odd 5 valve design. The later Yamaha 250 & 450 engines have much more sensible '3 inlet on one side' design. I imagine the split 2 & 1 inlet design of the Ducatti suffered from either poor scavenging or inlet charge being drawn out of the closing exhaust valves. 11,000rpm would have been amazing back then, but pretty much all single cylinder MX bike are way beyond that now using simple balance shafts.

[@victinim2512]

Who said single cylinders can't sound good.

[@dbmail545]

I was really hoping to see the twin crank single made with a KTM head.

[@andrea-fs1ty]

Bimota GB1, Gilera Saturno 600....

[@kleidtomasse]

Mototech made some duke 690 singles into what they call a ktm rc4 supermono sportbikes.. they look badass.. though ducati 550 supermonos are beautiful, they cost $150k..

[@joejoejoejoejoejoe4391]

Not only are the supermonos beautiful, I think they're V twin based balancing is clever, just need a morbideli 6 valve head.....

[@rodbrezinski8033]

What's the horsepower and torque numbers

[@dazaspc]

The 5 valve triple cam is really only a twin because the third intake valve is timed the same as the other two. Just to lazy to set up a decent valve gear. However it is a bit unusual for having an intake between its exhaust valves.

[@Lnz86Knot]

unusual, but very intelligent, it keeps the temperature in the combustion chamber homogeneous

[@benderbender1233]

[@jedisentinel1499]

Are these Motogp bikes?

[@1622yamaha]

Oops, I mean battle of the singles!!

[@pogpogcasino]

No wonder Ducati sounds like a tractor.

[@redtobertshateshandles]

You can buy a KTM single. I should get one.

[@lornespry]

YES! I've drooled over those little KTM sporty single road bikes. Very yummy!! If I ever retire my Yamaha SRX single, I want one. I've not seen a new one here in Japan for some time. I wonder if they are still made?
