Engine/Drivetrain

• Liquid-cooled, fuel-injected four-stroke, four-valve overhead-valve 675cc single cylinder engine is mounted longitudinally in the frame, allowing direct driveshaft alignment to front and rear wheels for improved drivetrain operating efficiency.
• Liquid cooling ensures consistent engine operating temperature in extreme conditions for maximum power output and long engine life.
• Camshaft is located adjacent to the cylinder head, reducing engine height. Together with the semi-dry-sump crankcase design, engine height is further reduced for a low centre-of-gravity and excellent handling.
• Four-valve cylinder head with two short pushrods provides a broad powerband for optimum performance and engine efficiency.
• NiCaSil-plated cylinder lining is lightweight and more durable than conventional steel-sleeve cylinders.
• Snorkel-type air intake system is specially designed for water crossings.
• New fuel injection system features 40mm throttle body, 12-hole two-pattern injector, and IACV (Idle Air Control Valve) for easier starting and smooth, consistent operation.
• Reliable cold weather starting.
• Consistent engine performance at high altitudes.
• New remote-mounted fuel pump with internal fuel reservoir maintains consistent fuel injection performance in rough and varying terrain.
• New IACV valve maintains consistent idle in all conditions.
• Engine design produces low emissions that meet all local European off-road emission standards.
• New transistorised electronic ignition with electronic advance for excellent performance and reliability.
• Unique semi-dry-sump oiling system locates the oil tank inside the engine cases, lowering engine height and allowing optimum engine placement for excellent ground clearance and superb handling.
• Standard high-flow oil cooler assures optimal engine lubrication under difficult operating conditions.
• Highly effective multiple-scavenging oil system utilises an oil pump with three sintered steel rotors (one for feed, two for scavenge) to provide a stable oil supply in diverse riding conditions.
• Unique temperature indicator uses two sensors to monitor both oil and coolant temperatures.
• High-capacity coolant radiator is rated at 20.2kW for efficient engine cooling in extreme operating conditions.
• Flat-shaped radiator fan motor is lightweight and compact, contributing to optimum engine placement.
• Rubber-cushion engine mounting system and gear-driven counter-balancer reduce engine vibration.
• Closed crankcase vent system safeguards against engine oil contamination.
• Rugged stainless steel exhaust system ensures superior corrosion resistance while minimising noise levels.
• Exhaust system silencer equipped with internationally approved spark arrester.

Chassis/Suspension

• Rugged steel perimeter-style frame and four-wheel independent suspension provide an exceptional 254mm of ground clearance.
• Separate rear frame utilises the final-drive gear case as a stressed member, reducing overall vehicle weight.
• The TRX680’s steering mechanism design provides light steering effort combined with a tight turning radius of 3.3 metres.
• Independent double-wishbone front suspension uses premium shock absorbers to provide 175mm of suspension travel for a plush, comfortable ride.
• Honda’s independent rear suspension uses a double-wishbone design and features forged aluminium knuckles and upper/lower A-arms to substantially reduce unsprung weight. Rear knuckle pivots use lightweight metal bushings in place of conventional ball joints and radius arms, eliminating toe-in as the rear suspension travels through its stroke. This simple design maintains rear wheel alignment and further reduces unsprung weight, contributing to responsive overall handling.
• Lightweight single-tube gas-charged rear shocks and an anti-sway bar provide plush, well-controlled damping throughout the TRX680’s exceptional 203mm of wheel travel.
• New dual front disc brake callipers feature a patented built-in scraper system to remove mud and snow from inside the front wheel to help prevent build-up of debris between calliper and rim to ensure consistent braking performance.
• Brake pads feature thick, long-wear material with improved mud durability, feel and control. Pads feature internal scraper that gives audible warning when pad life is low.
• A centrally located rear hydraulic disc brake and self-adjusting mechanical rear parking brake are mounted on the rear drive-shaft, further reducing unsprung weight and contributing to the TRX680’s considerable ground clearance.
• SUV-type radial tyres provide a smooth ride and exceptional handling. Tough, large diameter 25 x 8–12 front tyres and 25 x 10–12 rear tyres provide added ground clearance.
• Attractive SUV-style large-diameter 12 inch cast aluminium wheels further reduce unsprung weight and contribute to superb handling.
