GSX-8S New Parallel-Twin Engine:
- The 270-degree crankshaft configuration provides a comparable, but more powerful experience as provided by the 90-degree V-twin engine used in the SV650 models.
- The spaced nature of the engine’s power pulses enhances traction and contributes to ample power output at extremely low speeds, making the GSX-8S easy to maneuver in slow traffic or through tight corners.
- Suzuki Cross Balancer technology, used for the first time on a production motorcycle, helps create a compact, lightweight design that delivers smooth operation.
- The pistons were developed using FEM (Infinite Element Method) analysis to maximize strength and minimize weight.
- The 83mm cylinder bores inside the aluminum die-cast cylinders are plated using Suzuki’s SCEM process. Originally developed for racing and proven on the track, the SCEM cylinder promotes better heat dissipation, reduces friction, and provides a consistent wear-resistant seal to the pistons’ rings.
- Dual, linked 42mm electronic throttle bodies use a newly configured Accelerator Position Sensor (APS) to provide an authentic response and feel to the rider’s throttle operation.
- The GSX-S8 has two ten-hole, long-nose, 49 PSI (343kpa) high-pressure-feed fuel injectors that maximize fuel atomization for better combustion efficiency and lower fuel consumption.
- The 6.0L air cleaner box shape and intake pipe lengths were created using computer-aided design to help maximize peak power output plus strong torque production at low engine speed. Positioned under the seat, the air box size and shape contribute to the GSX-S8’s slim chassis.
- The GSX-8S has a new, distinctive short muffler design that produces an exciting and unique exhaust note. Most of the exhaust system is located under the chassis in an optimal, centralized location that benefits handling.
- The stainless-steel 2-into-1 exhaust system uses a high-flow, dual-stage catalytic converter inside the mid-pipe that helps satisfy worldwide emissions standards.
- From the mid-pipe, the exhaust flows into an under-chassis chamber that has a short new muffler design with an upswept end cap that slightly protrudes from the right side of the chassis.
- The digital ignition fires iridium-type spark plugs that increase spark strength and combustion efficiency, contributing to higher power, more linear throttle response, easier engine start-up, and a more stable idle. These quality components also last longer than conventional spark plugs.
- A large-capacity radiator effectively cools the parallel twin’s power output. A thermostatically controlled cooling fan helps stabilize coolant temperatures when riding at low speed and constant stops.
- The unique cooling system inlet control thermostat valve helps maintain consistent engine temperature and smooths the idle speed during warm-up. This helps stabilize combustion and contributes to reduced exhaust emissions.
- Additional heat is removed from the engine via the use of a lightweight and compact liquid-cooled oil cooler (like those used on certain GSX-R models).
SUZUKI Intelligent Ride System (S.I.R.S.) Features:
- A Suzuki Drive Mode Selector (S-DMS) supports the rider in matching performance to the riding and road conditions, or the rider’s preferred riding style.
