Four Ways To Play Fast And Loose With The Space/Time Continuum

Hard Parts

Frame
Triple box-section spars and a strapping cast-aluminum steering head bear most of the ST's considerable mass. Solid mounts let the engine assume load-bearing duties as well. Meticulously matched bolts sharpen chassis feel whilst helping to squelch nasty vibration.

Suspension
An aluminum upper triple-clamp holds 45mm cartridge-type fork legs securely. Sadly, they offer no external adjustments. The ubiquitous remote adjuster allows a 1.2-inch range of shock spring adjustment, while a somewhat less accessible screw lets you dial in rebound damping.

Engine
Smooth? Honda's big V-4 uses a 360-degree crankshaft and contra-rotating balance shafts. Heavy-breathing 31mm intake valves share each combustion chamber with 26mm exhaust poppets. PGM-FI injectors disburse fuel through 36mm throttle bodies as per the 3-D digital map. A catalyst in each 5.4-liter muffler cuts environmentally unfriendly exhaust gases.

Fairing
Honda calls the shape an Aero-Ellipse, a slick look intended to steer air efficiently around rider and passenger whilst facilitating high-speed stability. Outriggers on either side touch down first in a tip-over to save more expensive bits. Don't ask how we know.

Brakes
The front brake lever triggers the outer pair of pistons in each three-piston front caliper and the three-piston rear caliper. Pushing the pedal cues the center piston in front and rear calipers, while a delay valve slows actuation up front to decrease chassis pitch. A proportioning valve optimizes front/rear brake bias to conditions.

Horsepower: 114.1 bhp @ 7500 rpm
Torque: 83.5 lb.-ft. @ 6250 rpm

Dyno
Flat as its outboard-from-heck exhaust note, the Honda power curve defines efficient power. Torque in the basement? This one makes 77 lb.-ft. of the stuff way down at 3000 rpm, and thrust flows like a fire hydrant from there to 7500.

Ergos
ST ergos lean you forward to get the most out of a relatively small fairing. Shifting a little weight to arms and wrists makes four hours in the saddle tolerable. An excellent stock seat helps out on that count as well.
