Nesbitt devised a way of using the swingarm as the exhaust, by way of a triple-layer Inconel bellows connecting the headers to the curved, hollow swingarm tube. Thus far the G2 Hellcat is the only motorcycle design to route the exhaust in this manner; the Riedel Imme R100 used the exhaust pipe as a swinging arm, but the powerplant was rigidly attached to the arm/pipe and moved in tandem with the rear wheel. Twin Penske shocks supported the rear.

Adjustable 50mm Marzocchi forks and six-piston radial mounted brakes up front suggested a sporting machine, but a 240mm width rear tire and a carbon-fibre tractor saddle said something else before being drowned out by the fury of a too-much-is-just-enough 124 cubic inch S&S mill which thumped out 130hp and arm-wrenching 140 lb/ft torque at the rear wheel.

These massive engines and obscene power figures proved to be more than enough to fling the 530 LB brute down the road with the sort of immediacy and drama that made motojournalists wax poetic about the capabilities of what was supposedly an “antiquated” 45-degree twin - when they weren’t busy pointing out the astonishing $60,000-plus price tag, anyway. It performed like it looked – brutal, uncompromising, and awe-inspiring.
