why is the busa so heavy

i know this, i'm not a heavy guy, but i used to ride a 04 gsxr 600, my friend still has one and i got on it...::11...............man i was like :wtf: as soon as i took it off the kickstand it felt like a bicycle.... looking down at the gauges it just looks so small.....totally different world !!!
 
Try riding a big road bike that weighs about 700 plus pounds---then the Busa doesn't feel that heavy anymore.:laugh: Raise the rear up about an inch and it will be more manageable in the turns
 
This thread is cracking me up. Yeah, the Busa sure does seem to attract us guys who, umm, are gravitationally challenged.

But the thought of the thread is a good one and some folks have made some good comments. Probably the easiest thing to shed weight is to go to a 4-into-1 header and a lighter muffler can. You could swap out your rear subframe for the aluminum version of the early models. Remove the rear grab rail (it weighs a ton). You'll have to remove the tail section, but you could remove the grab handle on the left side that's meant to help you lift the bike onto the center stand. Install an aluminum side stand. The bottoms of the pilot's footpegs have big weights on them to snub out vibration. All the stuff above is probably good for maybe 35 lbs.

I imagine there are a few more parts you could easily swap out. Lighter wheels maybe from a GSXR1000?

As for me, I keep adding weight (saddlebags, Genmar riser). The bike has more than enough power for it's weight and a heavier bike is way more comfortable going distances, but it suffers for flickability and canyon carving. Depends what's more important to you. The new CBR1000 feels like a flyweight to me compared to the Busa.
 
Funny you mention the Roadstar--my sentiments exactly! Tho I still have my 03 RS in the garage and is a great two up ride.
Weight is all relative --to a lot of things--and this busa is my first modern sportbike with a tad bit of power. I try to ride the RS once a week to keep the the battery up--but that dont always work. For now I have to say that I like the "heavy" of the busa. If anything--It keeps the front end down a bit better and when it does come up--it's a little more managable for sport rookies like me.

The reason she's so heavy is found everywhere: the frame, the engine, the wheels, the exhaust, the tank, the bodywork. You can't really change the engine or frame without serious surgery, so unless you do this sort of thing yourself for kicks, that's out. To lose any serious weight, you'd have to replace all of the others: the wheels, tank, bodywork, and exhaust. When all that is said and done, you'd have spent upwards of 5 large, and you would reduce the weight by maybe 30-40 lbs - that's well over $100 per pound!!! That's why:
1) If you really want a lighter bike, buy a different bike from the start - it's WAAAY cheaper to have the manufacturer do this than you.
2) It is far cheaper to lose 10lbs from your person than from your bike, thus the advice about losing weight - he's not kidding.
3) But if you've got the time, money, and inclination, yes you can lighten the old girl if you really want.
Weight actually comes off a lot quicker than you think. Most exhaust systems (full, not slip-ons) suck a full 30 pounds off right off the bat. Wheels don't just lighten the bike, they make it much more responsive in turns due to reduced gyroscopic effect. Those 2 mods alone make the bike much lighter, more powerful and definitely more responsive. But like others said, a diet will shed several pounds real quick and make a noticeable difference. :laugh: Fortunately I'm not one of those that has to worry about that....not yet at least. Give the metabolism a few more years. :please:
 
these machines need overbuilt to withstand the abuse that some fools put on them.. crash landing wheelies can destroy a race frame, so they make it to take all you can dish out.. they are also kind of "long" and that length adds weight too..

IMO, I would rather the bike have the weight when cruising long miles.. the ride is a lot more compliant and you do not get beat up so bad.. (especially nice when windy)

Other than that, I think many Busa riders are on the heavy side... built to suit :laugh: big power, big parts.. ?

Who me?
109 kgs is not heavy!
How can you say such cruel things!:whistle:
 
dry weight is closer to 478.

If you want a lighter bike, buy a 1000

dry weight is probably even higher than that.

lbs per gallon roughly for fluids...filled up there should be less than 8 gallons of fluids on board including brakes, clutch, coolant, oil and fuel.

bike is 550+ in stock form.

I took off my grab bar, cut off the center stand grab handle from the sub fram, removed the weights from my footpags, changed out the exhaust to 4-2-1 stubby mega phone boz brothers b2.... weighed my bike on an industrial scale accurate to .005 of a once with a full tank of gas and all other fluids....she weighed 528#s
I imagine about 35-42 #s lighter then stock

okay...528- 40lbs in fluid.....then add your weights back on.

I would say that your estimate on your weight lost in reality was on the lower end of your guess.

I stand corrected, Suzuki lists curb weight for the California model at 480 lbs. But even at the stock weight a 2.70 to 1 power to weight ratio is still impressive!

Depends on the API gravity of the gasoline, which varies by grade and refinery. Usually, regular unleaded gasoline has a gravity of around 58 and a weight per gallon of 6.216 pounds per gallon. Premium gasoline may have a gravity of 54, or 6.350 pounds per gallon.

stock curb dry weight is 478#s 480#s on california model
Suzuki Cycles - Product Lines - Cycles - Products - Hayabusa - 2007 - GSX1300R
6.35 x 5.5 gallons is 34.925
plus 4 qts oil
gallon plus of antifreeze
brake fluid
etc
the new exhaust is 12 #s which is allot lighter then the stock cans for sure...

either way its lighter, even if its only 8-12#s I can tell... but then I put on schinko tires and they are a bit heavy...

if you want a light, roadracer...buy a GSXR

if you want the best, fastest bike on the planet...get a 'BUSA

if you want to be frustrated,spend lots of money and waste time.....try to turn your BUSA into a GSXR.
