TECHNICAL FEATURES A limited slip mechanisim is used in the front differential unitThis system is comprised of two sets of clutch discs and plates, each tensioned by its own spring, one set for each front wheelThe use of conventional front differentials on four wheel drive vehicles tends to make them difficult to drive when one of the front wheels loses traction, This is because conventional differentials transmit driving power to the wheel that has lost traction, causing the vehicle to turn to one sideWith limitedslip differential, even though wheel slips or is raised from the ground, the pinion gear and side gear are engaged by pressure from the fr iction plates certain portion of torque from the engine is transmitted to the other wheel, that still has traction, to prevent the slipping wheel from racing This characteristic allows the speed of the raised or slipping wheel to be much the same as the wheelan the ground, which prevents the front of the vehicle from turning unintentionallyWhen turn is initiated by the rider, the clutches slip moderately, causing differen ces in torque distributed to the inside and outside wheels, and turning resistance is decreased
