Why This Tiny Engine Can Go 200mph

Thanks to Valvoline for sponsoring today’s video! Click here bit.ly/Valvolin... and get the ultimate protection for your engine!
We took apart a Hayabusa engine to find out how this tiny engine is capable of deadly speeds… and then tried to put it back together. Easy, right?

As someone who made connecting rods for motorcycles for a good while, I think it's VERY important to look at that bushing in the rod/wrist pin and see if there's wear marks. On a motor putting out as much power as a friggin BUSA, revving as high as it does, I wouldn't be surprised if they were toast (depending on mileage/abuse), and that will blow a motor. I'm not sure how many bikes have bushings in the top end of the rods, but it's a very nice touch for very well engineered bike. ALSO 9:01 is why you tape a cloth to the top of your rods when assembling a motor like this. Any ding on the case could break a seal.

The ZX12r (the younger sister bike to my ZX9r, although mine is a Y2k bike), was a better bike all round as it could also go over 200mph unrestricted, but looked a lot nicer than the Hayabusa, subjective, but not really 🤣🤣

[@ShadowTheSC]

It is a fast bike because of how it looks, that was Suzukis entire goal. The body fairings were extremely aerodynamic.

[@CajunReaper95]

That’s not entirely correct bud, you still need the HP and torque on an engine and a light frame for that engine to sit on also as established before looks have nothing to do with the speed of a vehicle the ricer community in the car world has demonstrated that flawlessly that cosmetics have no effect on how the car performs and what truly matters is how much power you have at the wheels and how much weight you have to move when driving/taking off from a complete stop and often times “aerodynamic parts” can often slow down a stock vehicle with low horsepower and low torque but given the bikes engine has 175 hp and the bike is light there’s enough power to get it to 200mph!

[@Nobodysrider]

THIS WAS MY BIKE!! Can’t believe you guys got your hands on it! I have video proof on my channel.

[@Cocytus]

1:00 - Actually, the looks have a lot to do with its ability to reach 200MPH. When Engineers were designing the Hayabusa, they were looking to achieve the most aerodynamic body panel designs possible. It's designed to slice through the air as well as encapsulate the rider in a pocket virtually eliminating any drag that's otherwise seen on other less aggressive body designed bikes. Now while the engine is a fast revving high power output platform, it by itself can't achieve 200MPH. The body design is needed to coincide to make the fastest 200MPH speed happen. So the statement our Host made about it being very fast is done by the engine and not the looks, is inaccurate.

If you have to get the rods through the holes again in the future, tie some decently long strings onto each. Thread the strings through the hole then drop the top back on.

[@chrismoltisanti2763]

FYI on most sport bikes like the busa. The transmission is designed to be shifted without the clutch. Even without a quick shifter. It's the same design as those sequential dog boxes that you car guys use. Only need to clutch when taking off or stopping. Shifting you can just blip the throttle and rip into the next gear.

[@TylerTheBassCreator]

Most motorcycles in general

[@wildnfree223]

In general you're right, but in experienced hands, a slip of the clutch can often assist shifting under full throttle. Principally we need to create an " unloading " of the gear dogs momentarily to allow shift drum and fork to push the gear into the next gears dog. Either cutting fuel, cutting ignition or in this case slipping the clutch at full throttle creates that unloading and bam our sequential gearbox shifts ! Much love from Alberta Canada 🇨🇦

Back in the day this bike was pure death. I know a few people who died on this bike. Engine was ridiculously powerful with Akrapović exhausts reaching almost 200 hp. That was 17 years ago.

I feel like working with Jerry is an absolutely blissful experience :D

Takes motor apart, puts it back together. “This is why tiny engine can go 200mph”

I too didn’t like the look of the Busa at first. But now that im older, i absolutely love the look of the 2nd gen busa and still want one. Maybe when im done with my 1K it’ll be next

Walt Disney World used to have a big production where they showed how they filmed fact car chases and spectacular tricks. They used these small very loud custom cars powered by Hayabusa engines.

Please don’t forget the Kawasaki ZX12R. When it came out in 2000 it was driving real 308 km/h. But from 2001 the maximum speed was limited to 299. The ZX12R was a great bike.

I like all of Jerry's ideas at the end, but I'd like to add one addition. Everyone knows that the first mod for every self respecting Hayabusa owner is to add a turbo. I want to see this bad boy pushing well over 400 horsepower

Still Waiting for that second video ❤

There used to be a company on Vancouver Island in BC that imported Caterham 7's and put Hayabusa engines in them. They were reportedly absolutely srupid fast. Wish I had got one but the owner, David Saville Peck, passed away a couple years ago and no more are being made.

Try using ring compressors next time you install the cylinder block. MUCH easier!

1:13 not early 2000s. 80s-90s Japanese manufacturers were competing with each other trying to make the fastest bike. This culminated in the Hayabusa gen 1 release in 1999 with a top speed of over 300km/h and it would be restricted to 299 in 2001 with the gen II (people would find a way to tune the gen 2 for more power than the gen 1). The gentleman's agreement made after the gen 1 was why the gen 2 was limited as manufactures feared the government would step in if things kept going the way they were.

What I found many years ago in my youth was that you don't necessarily need a huge engine to go very fast after making my Chevelle with 283 and two barrel carburetor go 140
