No mention of HP numbers, just weight loss.

Suzuki introduced its new 2004 GSX-R750 and GSX-R600 during its annual dealer meetings Friday at Bally's Hotel and Casino in Las Vegas, Nevada.

The 2004 Suzuki GSX-R600's new engine has a bore and stroke of 67.0 x 42.5mm and a higher compression ratio, 12.5:1 versus 12.2:1. Weight has been taken off of nearly every part inside the engine including the new forged pistons, the crankshaft, the connecting rods and the new, hallow camshafts. The biggest news inside the engine is the addition of lighter Titanium valves, which are now set at a steeper included angle, 22 versus 28 degrees, with a straighter intake port.
Improvements to the fuel-injection system include lighter and narrower dual, double-barrel 38mm throttle bodies, which have one improved injector per cylinder. A smaller, lighter and more powerful Engine Control Module (ECM) has been added.
The GSX-R600's aluminum alloy twin-spar frame is all-new and is 15mm narrower than the old frame at its widest point. The new fuel tank is 15mm shorter and 20mm narrower at the rider's knees. The swingarm is now braced and the old forks have been replaced with Showa 43mm inverted units. Wheelbase is 54.7 inches (1390mm), rake measures 24.0 degrees with trail at 3.66 inches (93mm).
The front brakes have been upgraded to radial-mounted, four-piston Tokico calipers with smaller rotors (300mm versus 320mm) and a new Nissin radial-piston master cylinder.
Claimed dry weight is 354.9 pounds. MSRP is $7999.
Suzuki says it developed the GSX-R600 first then the GSX-R750 next to get a bike the size of a 600cc machine with the power of a 1000cc machine.
The 2004 GSX-R750 gets the same frame, swingarm, forks, brakes, wheels and geometry as the GSX-R600 but with a slightly longer wheelbase than the 600, 55.0 inches (1395mm) versus 54.7 inches. The 750 comes with many improvements in the engine department including new pistons, more compression, Titanium valves, lighter camshafts and a smaller, yet more powerful ECM. The 750 also gets a new, narrower set of single-injector, 42mm throttle bodies to fit inside of the narrower frame and smaller fuel tank. A curved and trapezoidal-shaped radiator is unique to the newest 750cc machine.
Claimed dry weight is 359.3 pounds. MSRP is $9499.
I wonder if they improved the steering of it? I've heard it's a stable bike, but steers really heavy. The R6s are the way to go for surgical precision steering.

DDRRRROOOOOOOOLLLLLLLL
the 750 has the same frame as the 600 !!!!!

Don't get too excited, I bet there are subtle differences. The wheel base is different so SOMETHING is different there.
And knowing Suzuki, they'll try to capitalize on us wanting to swap frames, engines, etc so they'll make the engine mount points just a few mm off so they don't fit (just like they did with the 01-03 models)
The reason the motor mounts don't line up is because the engine mounting bolts go in through the cylinder head. The cylinder barrel portion of the case gets taller as Suzuki adds stroke to go from 600 to 750 to 1000, So the cylinder head gets farther from the crank. Hence the upper motor mounting bosses must be welded to the frame higher up with each increase in displacement.
See? It isn't a vast conspiracy by Suzuki...
Furthermore, the wheelbase can be adjusted with different triple clamp offsets.
Which would also affect trail. I'll find a link, but there's an interesting trail calculator program that was posted on the WERA board.
Also, thank you Chris for clearing that up about the frames. I can't see a major motorcycle manufacturer changing an engine mount just for the sake of you not being able to interchange parts.

i talked to my friend Corey today who is a Rep for Suzuki....who told me in april that they were releasing the info in Oct. about the new 600. He told me then that the 600 would be about 6 lbs lighter and have 7-8 more HP. looks like he's right. He
told me today that the bike's power to weight ratio is
better than that of the R6... They haven't put out the HP #'s but He also said that it was Dyno'd with
636 type numbers. Guess we'll see. i like the new
swing-arm, but i'm not sure about the inverted forks.
won't that make the 600 too rigid up-front? anyway,
stock 600 with 108 HP @ race-prepped weight sounds
good to me ;D
Benji.#30 oh yeah, and mapped for more midrange
which is what we want!!!
smoke the ol' R6 outa the corners
Sorry, guys. New bikes don't do much for me.
Look at the reality of things. The tires won't be too much different between last year's 600 and this years. So, even if it had fifteen more HP, it probably won't be faster on the track...might not be noticeable.
Seems like there was a lot of squak about the Kaw's with the inverted forks and the radial calipers...EVERYTHING is about remarketing. The changes are there to get people to ride new bikes.
The bikes look nice, but the Japanese manufacturers do not do much in the way of one upmanship. They all want to sell everyone new 600's year after year after year. So, minor changes, revised chassis and bodies, BNG (bold new graphics), same stuff...different year.
Good luck!
