The press briefing revealed a startling, 13-pound weight increase between the '06 and '07 bikes, no doubt due to the new, larger radiator and related cooling components as well as the heavier dual exhaust. Some components did go on a diet, however, such as the brake system with new rotors that are .5mm thinner to reduce unsprung weight. You'd never guess that Suzuki changed anything in the brake department, though, as the GSX-R stops as authoritatively as ever. The front radial-pump master cylinder pushes enough juice to allow one-finger stopping from any speed, even into the Honda hairpin, and the new, thinner rotors give no indication of fade or other evidence of overheating, even when coming down from 175 mph (just a little) in preparation for Phillip Island's infamous Doohan Corner. Aiding aggressive corner entries is an effective, cam-operated slipper clutch mechanism that has had one more reaction spring added this year to more smoothly control engine braking.
