What's wrong with laying down a bike on its side?
I don't understand what cc and hp are. It seems like the more cc the more powerful a bike is?
In theory nothing is wrong with laying the bike down on it's side.
However, fuel, oil and other liquids can flow into areas where they are not supposed to. Also, there is no easy way to store the bike on it's side: IE kickstands and the like.
However, if you drained all the fluids, and had a nice soft spot for it, and and easy way to pick the bike back up, go ahead and plop it on it's side.
I can't understand why you would want to, though.
CC stand for Cubic Centimeters. The bigger the number, the more volume you've got for combustion to occur. The bigger the explosion, the more power you get. This also explains why your lawnmower is not nearly as powerfull(or loud) as a bike motorcycle.
Enjoy.
but Wait!!
What does it have to do with hp then?
I've been hearing about some motorcycles having more horsepower but less cc and stuff and I'm still confused.
Relation between hp and cc?
i thought hp was power
I've also heard about the GXR1000 being the fastest or something.
But I thought the hayabusa was fastest?
hp = horse power
Power=work/time
power is the rate at which work is done, and is measures in watts. work is measured in joules. 1 joule per second is called a watt.
horse power is a specific amount of power.
it is deffined as:
1 horsepower = 550foot pounds/ 1 second
or 746 watts
so a gs500, which makes on average 44hp, could also be said to make 32824 watts.
It's not quite that simple.
In a perfect work more CC = more HP.
However, number of cylinders and number explosions per second, weight, timing and all sorts of things affect performance and HP.
Now then, the laws of phisics dictate that you need 4x the HP for 2x the weight. HUH? :? If you're bike weighs about 50 lbs and has 10 HP, then a 100lbs bike would need 40HP to have a similar level of performance.
The gixxer is WAY lighter than the busa. It has more sporty performance, but the BUSA has a higher top speed. The GIXXER will reach it's top speed faster, but the BUSA will pass it eventually(if the course was long and straight) because the top speed is higher.
Now then, if you take your average twin versus your average I4 engine, the inline engine will have 2x as many explosions(power strokes) as the twin. The more explosion, the more power.
NOW then, you may see some twins that can take some I4's. Keep in mind that valves per cylinder affect performance. 2 valves per cylinder usually means more low end power, and 4 valves usually means more high end power.
There's still more to it than that, but it gives you an idea.
I'm sure other people can explain how the twin/I4's differ.
Horse Power is a literal measurement of work, and measure the acceleration of a mass. Torque is similar but is the measured ability to move 1 lb. over a certain distance (I think, I may have the two muddled up).
"CC" is just the basic displacement measurement for an engine's volumn. It gives you a rough "ballpark" for power (HP and torque) but alot of other things affect how much actual power you get out of a given sized engine.
Take the GS500 vs EX500 for example.
Both have roughly the same displacement, ie: cc. But the EX's engine is liquid cooled so its piston to cylinder clearance can be tighter, has 4 vavles per cylinder so breathes better. And so it makes about 10 HP more than a GS in stock form.
As for your example, a GSX1300R does have a more powerful engine than a GSXR1000 but not by much because the GSXR mill is designed using lighter, faster components, and the GSXR is MUCH lighter than the Hayabusa. So on a drag strip a 'Busa might beat a GSXR1K, but on the track a Gixer would easily out run it.
Everything in motorcycle performance is interconnected. That is what is so cool about them. :)
you also have to figure in things like, tire size, wheel diameter, wheel base, and gear ratios just to name a few.
Damn now those are what you called some detail explainations about horse power and cubic centimeters. If anyone didn't understand the difference before they should now. :mrgreen: Now here is a question for you all, what would it take to find out the torq ratio to horse power. I know we have the nifty charts laying around on different sites. But would you need a specialized machine to find out these (torq and hp) ratings? I have seen posting of ppl placing there machine on a Dyno for hp rating but what about torq? BTW if you look on the front(or side in some cases) of your engine you will see the cc of the engine you have. On the GS 500 is shows 487cc(pretty sure, not infront of mine to look).
Why doesn't Suzuki just make the Hayabusa with the lighter gxr components then? won't it top speed be even higher?
Dang, before I wanted to ride a Hayabusa eventually. The way it was described was really appealling to me. Stealthy to radar guns, the way it's so visually appealling, etc.
Also, what do you guys think would be a motorcycle map for me starting from 1st bike to last? I can't go from gs500e to hayabusa huh
I still haven't ridden one before but I plan to soon

Just a tidbit for ya, everything else was pretty much covered...
Torque and HP ALWAYS cross at 5250 rpm on a dyno in any internal combustion engine.. This is a good way to look out for fake dyno results as well. Just make sure that both curves are on the same scale before you call :bs: tho...
The Busa is a sport Turing bike. It's meant to be more comfortable on long rides.
the GIXXER is a racing bike, not designed for comfort.
GS500, SV650, Katana 750, BUSA.
Perhaps even somthing inbetween the can-a-tuna and the busa
Wait guys, so the GXR is for racing and not for street riding?
So basically what I'll eventually want is the busa and not the gxr?
Anybody have any other suggestions for a motorcycle map?
Any non-suzuki suggestions?
Anybody against skipping the SV650 straight to the katana?
Just too clear this up, I will throw in the exact explantation of BHP and Torque. I know its already been covered, but slight errors occured,a dn there is something else to explain here. I am 100% correct on what I am about to write, for I recently had to understand it exactly in mechanical engineering. Its a basic thing:
The English unit of torque is written lb-ft. Try to imagine something weighting 1lb on the end of a weightless rod that is 1ft in length and you are holding the opposite end.
There is also another unit in English terms known as the ft-lb. It is completely unrelated to lb-ft. A ft-lb is the unit of work required to raise a 1lb mass 1 vertical foot.
As for BHP (bhp): 1hp is 550ft-lb/sec. YThis is raising a 550lb mass 1 ft in 1 second. You can also break this down in differant forms for example: raise 137.5lb a distance of 2ft in 0.5.
BHP is brake horse power. Brake horse power is measurent on a brake dynamometer.. You are in fact measuring the engine torque its absorbing. Here is how it relates: BHP= (torque x rpm)/5252 when torqu is given as lb-ft and RPM is obviously revolutions per minute.
Its is all quite confusing to just read.
A good example to understand cc versus hp is this: A dodge Viper has 8300cc and 505 hp. This engine is aluminum V-10 with 2 valves per cylinder. A relativley low tech, but highly effective engine.
A Porsche 911 GT2 has 3600cc and 475hp. This engine is an Aluminum flat 6 cyclinder with 4 valves per cylinder and is turbocharged.
There is no direct correlation to cc and horsepower, however in most cases it is safe to assume the more cc's, the more hp you are going to produce.
Cubic Centimeters (cc) are the metric form of engine displacment. Where as Cubic Inches (ci) are the standard form. You could read that the Vipers engine is 505ci engine rather than an 8.3litre or 8300cc engine.
a GSX-R 1000 can also be used for streetriding. The point is that it's pretty uncomfortable in comparison with the Hayabusa. on the Hayabusa you have more room and you won't sit as cramped as on a GSX-R.
Both bikes have an insane amount of power for road use. You can't snap the throttle all the way open if you feel like it, it probably would start to wheelie even at highway speeds and in a few seconds you would be riding waaaaaay to fast. (from 0-125 mph takes only 6.7 seconds with the Hayabusa).
I doubt if it will be a lot of fun to ride on the road.
After the GS500 or SV650 you could go for bikes like the Honda CBR600. the 600s are a bit in between, but still have lots of power. (from 0-125 in something like 11,5 seconds).
Don't forget that in comparison with cars, even a GS500 is fast. Just work your way up slowly. That way, you'll become a better rider than someone that starts out on a big sportsbike.
Why plan now? Get a GS and see in a year if you want something else. No need to make decisions, or even scope out possibilities yet, you don't even know what your riding style is going to be in 6 months time...
You might well want to ride a gixxer eventually, it just depends on what you want to do with it, if you really want to *go* places, you may be better off with a tourer, if you're more of a canyon carver, the gixxer may make more sense. One of the things I love about bikes is trying a new 'flavour' of bike :mrgreen:

you can call me a dumb ass....but, the last dyno run I did.....did not take tire size, wheel diameter, wheel base, and gear ratios into consideration.
acceleration, time, and RPM are used to calculate TORQUE and HP.
and a puter spits out a pretty graph to ruin your day...38HP-42HP
it was really bad when we put my YSR50 on the DYNO....5.3HP ...had to run with the choke....to be able to turn the drum :o
you know the ironic thing :? , the busa and the gix are not that much heavier than the gs, correct me if i am wrong, but the gs wet weight is+-420 lbs :thumb: :bs: ?
370-380#.... :cheers:

I won't call you a dumbass, but please try to read posts in context. He was asking about top speed as it relates to horse power and engine displacement.
dumba...
oops! sorry. almost did it anyway.
Compression ratios also figure prominently into the HP per CC thing. Fuel burns with more explosive power when compressed. A 500 cc engine with a high compression ratio could theoretically have more HP than a 600 cc engine with lower compression.
You also have to take intake/exhaust dynamics in mind.
Good point Glenn. That is very true.
However, if you have a turboed engine, you want a lower compression ratio. I guess turbo's arnt as important in a motorcycle forum.
What is the GS500's compression ratio anyway?
Quote from: Rich500What is the GS500's compression ratio anyway?
9.0:1
By comparison, the Ninja 500's is 10.8:1
Most supersport street bikes are in the 12:1 range.
what happens if you raise the compression of the GS? like are there any adverse effects?
you would need to run higher octane fuel.
I know if you buy a GSXR 750 stock, they want 105 octane. What a joke, you can't buy that kind of fuel anywhere.

There are a few different octane ratings. The one they are talking about is probably not referring to the one we use in the US printed on our gas pumps.
Higher than what? Higher than the premium (92 octane) I already run?
Wait a second, somehow I thought that the highest octane rating was 100.
100 as in no impurities?
and as it goes down more and more crap is added like lead
Octane rating has nothing to do with impurities or ingredients in the gas. Octane is a way of measuring how fast gas burns. The higher the octane rating, the slower the gas burns. This is why higher octane is only needed in high compression engines or ones with advanced timing. Octane rating has nothing to do with making more power in normal engines.
They say to use high octane gas if you are experiencing "knocking or pinging". This is caused by the gas burning too quickly for your engine and the explosion takes place too early in the piston's travel back up the cylinder. High octane gas makes the explosion occur slightly slower and puts it back in it's proper place in the cumbustion sequence.
I'm on CRACK, I meant 95 octane. :roll:
The highest available stuff is 94 untra from Sunoco. He was supposed to add octane boost with every fill up.
Just for reference you buy octane in levels over 100 octane.
At drag strips they usually offer levels in the 110's.
They due contain lead but if you are not using a cat and don't mind swapping out your o2 sensors often then you got some head room when tuning for maximum power.
Here in So Cal you can buy 100 octane unleaded at some of the local gas pumps.
As it has been said here before, higher octane gas will allow you to make more power in an engine that has higher compression ratios and/or advanced ignition timing that requires higher octane fuel in order to operate at maximum efficiency. Mind you a stock 5.0 mustang only requires 87 octane and using any more will not gain you more top end on an otherwise stock motor.
When they "ask for 105 octane" they are most likely referring to the research octane number which is what they go by in Europe.
The gas that is sold in America is RON (Research Octane Number) + MON (Motor Octane Number) divided by two as is expressed on any gasoline pump that you use. These two numbers are derived by testing a gasoline's resistance to pre-ignition (knocking, pinging) in high load and low load situations.
Usually RON numbers are about 4-5 points higher than the (R=M)/2 method we use in the US which would give an effective required octane rating of 100 octane which as I stated before is available at certain local gas stations at the pump but costs around $3.50-4.00/gallon. :o
Don't get me started on those octane boosters in a bottle.
You might as well buy some illuminated windshield washer nozzles to increase you 60ft times. :guns:
