ENGINE

The 1299cc engine was all-new in 1999, both more powerful and more compact than the ancient GSX-R1100 mill it succeeded. Piston and valve diameters expanded while all other internal parts were slimmed down to reduce reciprocating mass. Digital, ram-air-assisted 46mm throttle bodies kept it on the cutting edge.

CHASSISThe older Hayabusa's aluminum twin-spar chassis was credible in '99 terms, but not nearly as technologically advanced as the bodywork or engine it carried. The geometry (24.2 degrees rake, 3.9 inches trail, 58.5-inch wheelbase) is dialed more for high-speed stability than razor-sharp handling.

BRAKES

If four is good, six must be better, right? Six-piston calipers were a signature Suzuki spec dating back to the mid-'90s. Braking performance is decent by '99 standards, but downright limp compared to de rigueur radial-mounts common in this century.

BODYWORK

Thousands of hours were spent in the wind tunnel to make the Hayabusa the most aerodynamic motorcycle ever manufactured. The jowly fairing, deep-skirted front fender, integrated turn signals and bulbous tail hump were all painstakingly shaped to cheat the breeze and build big speed.

DYNO

The first-gen Hayabusa makes power across a broad rpm range, producing 80 lb.-ft. of torque at just 3500 rpm and building from there. Stout midrange makes the original 'Busa feel untouchable on the street-until you ride the '08.

ERGOS

Hayabusa ergos are more sporting than touring. Seat-to-peg distance is tight for over-6-footers-Buell XB foot-rests can be installed to lower the pegs another inch. The seat-to-bar reach is likewise long, identical to a GSX-R1000 at 29 inches.

Hard Parts

ENGINE

A 2mm stroke increase that bumps displacement to 1340cc is just the beginning-the connecting rods and pistons are new, along with a crankshaft that is now grooved to improve oiling. Titanium valves on lighter single valve springs reduce reciprocating mass, and new double-barrel SDTV throttle bodies deliver fuel.

BRAKES

Four-piston, radial-mount Tokico calipers pulled from the GSX-R1000 parts bin are among the most appreciated upgrades to the new 'Busa, actually capable of slowing this heavy, high-speed hauler down. Smaller-diameter 310mm discs reduce unsprung weight to help quicken steering somewhat.

BODYWORK

Design manager Koji Yoshiura worked doubly hard to update the 'Busa's looks without abandoning the original iconic form. The end result is a bike that looks striking yet familiar-the effect is especially dramatic in person, when you can better appreciate the more complex shapes and added dimension.

CHASSIS

The second-gen 'Busa chassis is refined, not redesigned. Frame weight is down slightly in '08 thanks to the removal of extraneous brackets, and the subframe has been beefed up with stronger, badonkadonk-proof rectangular steel rails that have been dropped a half-inch to reduce passenger seat height.

DYNO

The dyno traces are virtually identical to 8250 rpm, where the '08 bike diverges to a 16.3-bhp top-end advantage. Despite similar midrange numbers, the quicker-revving, shorter-geared '08 feels more powerful on the road.

ERGOS

The cockpit of the new 'Busa is slightly roomier than before, with an added .7 inch of legroom and a .5-inch-longer reach to the bars. These changes, along with a .6-inch-taller windscreen, give the '08 bike a comfort advantage.
