Ahead of the Pack
The RM-Z450 continues to evolve for 2015, delivering a higher level of performance while maintaining the great balance from the previous model.
The 449cc 4-stroke liquid-cooled DOHC 4-valve fuel-injected engine along with new performance upgrades straight from the factory race bike is the reason why champions choose Suzuki!
The 49mm Showa SFF-Air suspension is an evolution of the original SFF system with no fork spring, reduced weight, increased inner tube diameter, and increased damper rod/piston size. The SFF-Air is made of 3 chambers and riders can change the spring rate with an air pump instead of changing out the fork spring/s.
The Suzuki Holeshot Assist Control (S-HAC) is a selectable launch mode system derived straight from the factory race bike to help riders launch from the starting gate for an early lead. There are three modes so riders can choose the best option for their skill level and riding conditions.
A Mode: For hard surfaces or less than ideal conditions at the starting gate, hold down the S-HAC switch for more than 0.7 second.
B Mode: When there is better traction and a more aggressive launch is needed, hold down the S-HAC switch for more than 1.8 second.
Engine starting has been improved with a longer kick starter lever for easier operation, a redesigned kick drive gear, a relocated kick idle gear, a newly added breather gear, and a redesigned decompression system that works more precisely and efficiently.
A redesigned frame increases rigidity and reduces weight by 4% from the previous model.
Cooling performance has been enhanced with the radiator hose connection being changed from a T-shaped to a Y-shaped design for more equal water flow between left and right radiators. Water flow is also increased by 16% with a redesigned water pump cover and the water hose is now directly connected to the water pump.
