2009 Star V-Max | Price: $17,990
A quartet of 48mm Mikuni throttle bodies fuels the fire under orders from Yamaha's familiar fly-by-wire throttle. YCC-I variable-length velocity stacks measure 150mm to optimize torque until 6650 rpm, then shift to 54mm horsepower mode after that, creating a virtual V-Boost kick in the pants. A hybrid chain/gear cam-drive system helps keep the top end compact. Cam covers? Magnesium. Mufflers? Titanium.
The 52mm Soqi fork carries cartridge-type internals, with an oxidized-titanium anti-friction coating outside. A cast-aluminum axle carrier caps each extruded-aluminum slider. As with the Soqi shock, spring and damping rates balance control against compliance, but some harshness crashes the party on rough pavement.
The V-Max skeleton is cast aluminum. Yamaha's Controlled-Fill Die-Casting technology let engineers vary wall thickness from 3 to 6mm, concentrating rigidity exactly where it's needed. Swingarm is cast aluminum as well.
A Brembo master cylinder cues six-piston Sumitomo front calipers and suitably huge 320mm rotors. In the rear, a single-piston Akebono unit squeezes a 398mm disc. The reassuringly potent combination slows all 700 pounds down with minimal drama and no fade.

Acres of bottom-end torque make the 'Max feel ridiculously quick on the street, but overpower the phat rear Bridgestone tire at the strip. Nothing else cuts a swath of triple-digit torque this wide.
More bar rise and legroom plus a lower seat sit you up straighter than on the 'King. That mammoth V-4 makes the 'Max thick through the middle, making short legs stretch to the tarmac.
