Sweet Spot setup is 540 lbs

my Gen2 with Carbon wheels , lithium battery , no engine balancer ,lighter stronger rods and forged pistons lighter, akrapovic carbon 4 into 1 - weighs with 1/2 tank of fuel (no abs pump) 230kg or 507 lbs
so a full tank is 238kg or 525 lbs
Crazy to think a stock GSXR 1k weights 440lbs wet and has the same hp (or more) than a Hayabusa......

But after a short time in the seat, a person would be looking forward to the relative comfort of a Hayabusa.

My GSXR 1K was lightened up quite a bit and it was a beast.
 
stock rods weight 394g
Wossner rods weight 3440g

that's 200g per set or 0.44 lbs

stock 81mm Gen2 pistons and pin = 307 g
84mm CP pistons and pin = 231 g

that's 304 g or 0.67 lbs

quite a lot less inertia being swung around

so 1 pound saving on pistons and rods
 
can confirm, coremoto wheels are pretty sweet, had them on my R1M.

find it hard to pull the trigger on carbon wheels, as once they crack thats it, theres no repairing that and even if there were, would you trust it? =D then again, stepping out your front door at all is a risk so, hey..

Rotobox wheels are mighty strong they have a 1/8" wire moulded into the wheel rim bead

After removing the balancer, u can also balance and lighten the crank as well, knife edge, remove the gear.

Billet one piece inner clutch basket to replace the stock two piece with the studs will also lighten up the spinning parts.
 
Really??
Have you ridden a 600 lately?
I have, and getting back on my Busa was like riding a tank lmao!
I was definitely being more metaphorical than literal. But the reason I use the phrase sweet spot is that the busa is still a GSXR. Show me the lap time of any other bike that weighs 540 and I'll bet the same rider would have a lower time on my bike...

Our own @Ac41 proves that the big 'ol buffalo will go around a track with authority......

I plan on doing a track day at Barber if not next year then the year after. I surprise people all the time with how the Busa can handle on the street I really want to see what I can do on a track. Of course not pushing more than 8/10th I don't want to crash my bike and Barber WILL send you a landscaping bill if you tear up their grass lol.

Paying to fix grass, lmao...that's terrible

The other factor is that my awareness is fairly high and I'm naturally gentle on my machine. Many people aren't and I don't understand it. It's the exact same confusion as letting a woman drive your car and watching her go right over the pothole when she had plenty of time and space to twitch the steering wheel and avoid it. Lack of awareness just baffles me.

After a few laps your nervous system will recalibrate to life in the top third of the RPM range. But the biggest surprise for most people is the lack of adrenaline. Most people think of the track and think of fear at the limit, but it's actually the opposite. Working on smooth technique over and over again becomes sort of relaxing. That's what's great about the track, it's a deliberate environment to reduce surprises, so every repetition can be tweaked just a little better. I think the track is the only place in motoculture that teaches and values the concept that smooth is fast. You don't hear that anywhere else. Another great article I read years and years ago called the track "The most honest place I know." What the writer meant was that braggadocio shrivels to death in a place with lap times, so humility is much more in evidence than ego. I like that.

I push track days (really schools) on younger riders with the reality that you will get 10 years experience in a day, and those skills absolutely can and probably will save your life on the street someday.

*And yeah it's fun to surprise the liter bike guys who've never ridden a bigger bike and consider the Busa to be pretty much a Harley. Every track will have a few corner exits which are the perfect experimental laboratories for displacement torque versus RPM horsepower. By the end of the day you may find yourself comfortable pushing 9/10 in the corners (provided you can a) get your ass off the seat, b) balance well enough to hold no weight on the bars, and c) move your center of mass forward enough to balance the load on the suspension equally between front and rear). And 600s are just snacks on the straightaway.

No issues with my Rotobox, Amazing product. Obviously, you are not going to ride in a hazard road with a lot of holes if so wheels will crack. but i understand your point if you won't feel comfortable with CF wheels keep your stock wheels.

.....and it's a good workout too.....

I was able to do the California Superbike school and our Canadian RACE schools back in the '80s then got to race for Suzuki as a semi-sponsored rider....
We bicycled the track in Cali to learn it and set our lines before we ever swung a leg over the seat of a motorcycle....

It was a great experience....I can only imagine just how far advanced modern race schools have become.....we rode GPZ600s in both schools as they were cutting edge in those days....

I have the same wheels in std black
I once had a front tyre blow out at 90mph neatly had an off
Bars waggling once than a mad bull , tyre practically on the rims - no damage

I have hit plenty of bad pot holes in 7 years of wheel ownership no cracks they are fine
