Busa Turbo, otherwise people will know you're gay.


Sport bikes and other motorcycles in general don't have and don't need forced induction units (turbocharger, supercharger, NOS) because of the power to weight ratio being 100 times (don't quote me on this number) more efficient than sports cars with 4 wheels. Even with sports cars and super cars I would rather have a Naturally Aspirated power train with a steady flow of acceleration rather than a big boost from a turbocharger. It also saves on fuel consumption this way and makes the engine more reliable, last longer and gives you better control of your ride.

If you want your bike faster, just install after market performance mods for it and make sure you tune the braking and handling characteristics properly as well.

I decided on not purchasing and riding a bike anymore also because in the United States we have speed limits on the road.
Thanks to everyone who contributed to this thread! :thumbsup:

Aftermarket mods like exhausts don't net any big gains in power, typically only a couple to a few hp if any. Stock brakes are generally pretty good on most modern sportbikes, but suspension upgrades are usually a worthwhile mod.

Turbos actually are used to make fast bikes even faster (Turbo Hayabusa for example). This is typically for drag racing or to increase the top speed as motorcycles are limited by aerodynamic drag more than anything else and they need a lot more power to get a small increase in top speed. A stock Hayabusa is limited to 186mph top speed but unrestricted they will do high 190s.

Sport bikes are pretty fast already though. Most modern literbikes can run the 1/4 mile in 10 seconds flat at around 150mph, do 0-60mph in under 3 seconds and reach 100mph in first gear.

And no, the power to weight ratio is nowhere near 100 times better for a bike.

That's the thing. I don't need a bike to go 186 MPH or even past 123 mph on the streets. I'm all for top end power, but most of the time I wouldn't even be on a race track and have no access to the high speed Autobahn.

I would rather have a < liter bike say a Honda CBR 600RR or Yamaha R6. It would be nice to have it tuned by a shop to decrease the top end power and instead give it a nice torque and mid range punch instead when I rev it up high. 600cc sport bikes also have smaller mass and are lighter so they're a bit easier to handle as well. I agree, sport bikes are plenty fast enough stock if anything.

Also, you mentioned 100 mph on 1st gear? Did I read that right? That's a tall gear ratio for just the 1st gear!

Like I mentioned I've never ridden a motor bike before. So I have no clue on how the riding experience would actually feel like. I still have some interest in riding, but like I mentioned a 49cc or 150cc scooter would be a better place to start...

Well, that's for a 1000cc sport bike. And yes, they will hit 100mph in 1st gear. This is due to the power and rev range those bikes will make, they deliver power in a very linear fashion all the way to redline which is almost 14,000rpms.

This guy isn't even on it.

Personally, I think a 600cc sport bike is not a good choice for a new rider either. If you're serious, start on something like a Ninja 250. Learn to ride it and then if you want to step up to a 600cc sport bike do it after you've learned how to ride. You'll learn faster on the smaller bike and they are much more forgiving.

Watching the guy take off made me cringe. Its like it's his first time riding a motorcycle.

I know, he over revs it and slips the hell out of the clutch... total n00b and a perfect example of why people like that should not be riding bikes like that.

i thought the same thing. horrible throttle/clutch control. when i start mine, i barely kick it above idle to get into gear.

I think you guys are being a bit critical of his launch techniques. Ya, he used too much clutch but nothing in the video screamed OMG N00B! to me.

Perhaps you guys would like to upload videos of yourselves launching liter bikes so we can compare technique? =]

Well, first of all he wasn't "launching" it. He was just starting out from a stop... and he hit 10k rpms before he even started letting the clutch out which is completely pointless. I don't think I need to get into the needless and prolonged slipping of the clutch.

Nothing about his video leads me to believe he has spent much time riding motorcycles... it was just the first vid that came up when I did my search.

I'm sorry. Trying to go fast from a dead stop. Was that a bit more correct?

So someone starting from a dead stop, obviously trying to go fast isn't going to slip their clutch and rev their bikes? His skills aren't great at what he's trying to do but it's quite obvious what he is trying to do. I'm sure he is capable of accelerating from a stand still without hitting 10krpm and slipping the clutch for 5 seconds.

Nothing about his video leads me to believe he has spent much time riding motorcycles

What exactly in a video like this will give clues as to how long someone has been riding. An individual takes off from a dead stop and revs their bike to red line in first gear then cuts the video. He could have 10 years of riding experience under his belt and not be good at fast starts from a dead stop. Or he could have only 2 months of riding experience.

OMG NOOB you over rev'd your bike and slipped your clutch too much N00B. That's pretty much what I hear from the comments. Which then my response is, I think you're being overly critical.

You're sure of that? Because he does it twice in the same video.

Clearly he hasn't mastered the clutch and throttle of that bike. I've ridden dozens and dozens of different bikes and I've been riding for a number of years and I can tell you that I NEVER do what he does in this video. Yes, some revving and slipping of the clutch is required to launch a bike. But he's not even accelerating at the limit so that much revving and that much slipping is completely unnecessary.

His launch is cringe worthy... especially the second one.

Here is a video of someone properly launching an R1.

Just watched it again.
Same cringe.
Its like someone whose riding experience is 1 day MSF course, 1 day on a 250 with a fat chick\dude on the back and 15 minutes on a bike he has never ridden before.

rev to 10K
let out clutch slowly
Casually accelerate in the process. (notice the ground while he's reving\slipping the clutch)

I half expect to see his feet sticking out (off the pegs, sticking out just in case he tips over) dragging them the entire run up to redline.

A quick look at his other videos turned up a lot of uneventful cruising and one ride where he couldn't maintain lane position (however, seems like a lot of riders and drivers ignore "road markings"

The guy could have tons of experience.
Nothing in the video posted by JulesMaximus says he has experience using a clutch on a Motorcycle. It made me cringe just to watch it.
Its just one video
Made me cringe
Guess that is all I have left to say about it

an experienced would be expected to know how to clutch/throttle with minimal slippage?

I would hope so. However, If I asked you to sit at a red light and rev your bike to 10krpm...would you have the experience to know how much clutch is needed for minimal slippage? Perhaps you would or perhaps you don't? I assume either way that you're a competent enough rider.




Maybe my statements above were unclear. I don't believe I said he was any good at what he tried to do. It's quite obvious he did multiple things wrong. What I do believe I implied was that just because someone tries to do something on a bike like that, doesn't mean they aren't an "experienced" all around rider.

Finally, to drive my point forward a bit with that thought process, I simply asked anyone critiquing him to post a video doing the same stupid thing he did. I want to see a video of you guys reving you're bikes to whatever rpm makes 80% of your max horsepower from a dead stop. I'm sure we'd all love to see you're clutch control in a situation like this.

What?

Your asking me to sit at a red light and film myself revving like a retard?

it doesn't guarantee that he's an inexperienced rider, no. but there's a damned good chance he is. or at least dumb (burning up his clutch for no good reason)

The simple reality is the fellow was demonstrating a technique that puts excessive wear on the clutch. An experienced rider doesn't do that because there is no benefit to doing it.
I'd happily post a video of me taking off on my bike, but it won't spin 10k rpm's. If you'd like to see what 2500 does, I'd be happy to show you.

Why the hell would an experienced rider do that?

Let me put it to you this way, he probably stalled it a dozen times before making this video so revving it to 10k rpms was the only way he could "launch" the bike without stalling it.

It is obvious to anyone who has ridden a motorcycle that he is a n00b because he revs it to 10k rpms and then slips the hell out of the clutch to get going. Not sure why you are defending him quite frankly... this is not really up for debate. It's not anywhere near the correct way to launch a bike... any bike. Or any car for that matter.

Actually, even for cars with a manual transmission, when you rev something say a VTEC honda at 7500rpm while fully stopped from 1st gear the car "peels out" and even this is not good for cars as well.

Not the way the fellow in the vid was doing it. If you're trying to light up the rear tires you want to hit the gas and pop the clutch. The only conditions under which you'd try to take off with high revs and slow clutch is if the vehicle is badly over loaded, or on a god awful step hill.

Try driving in downtown San Francisco sometime. I once had to drive on a REALLY steep hill there in gridlock traffic going uphill, creeping VERY slowly as well. While everyone was either fully stopped or could move smoothly with their automatic transmissions, damn you should've seen how embarrassing it was for me to be the only one riding the clutch and accelerating upwards trying to keep the vehicle from going back downwards. I think the SFPD on standby had a big grin on his face and being entertained watching me!
It was also raining cats and dogs and almost zero visibility didn't help.

I can't even imagine what its like in other places where it snows....
Wow, talk about a test of one's patience!
