The latest iteration of the championship-winning Suzuki RM-Z450 has landed in Australian dealerships.

Arriving on the cusp of back to back Australian MX Nationals MX1 Motocross Championships, the 2015 RM-Z450 continues the evolution of one of the most legendary nameplates in motorsport.

Delivering a higher level of performance while maintaining the great balance that defined its predecessor, the latest and greatest Suzuki boasts a host of performance upgrades straight from the factory race bike.

A highlight of the 2015 model is the new 49mm Showa SFF-Air Triple Air Chamber (TAC) front fork.

A radical progression from the original SFF system boasting no coil spring, outstanding weight reduction, increased inner tube diameter and increased damper rod and piston.

The SFF-Air consists of three chambers and riders can alter the spring rate with an air pump instead of changing out fork springs.

The new bike also comes standard with Suzuki Holeshot Assist Control (S-HAC). The selectable launch mode system comes straight from the factory race bike to help riders achieve the perfect start.

The system comes with 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
B Mode – When there is better traction and a more aggressive launch is required
Off – Standard map for normal starting performance

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 restyled decompression system that works more precisely and efficiently.

The reworked frame offers the twin benefits of increased rigidity, while delivering a four per cent benefit in weight savings over the previous model.

Cooling performance has been enhanced with the radiator hose connection changed from a T-shape to a Y-shape design for better water flow between the left and right radiators.

Water flow is also increased by as much as 16 percent with a redesigned water pump cover, while the water hose is now directly connected to the water pump.

Gear shifting feel has been improved with a revised gear shift cam for more precise changes. The machining process of each gear has also been refined to increase the precision between matching gears.

In total, the 2015 Suzuki RM-Z450 represents a significant step forward from the bike since its introduction has won 17 major motocross and supercross championships worldwide.

In addition to its mechanical overhaul, the price has been streamlined as well and is available now for a recommended retail price of just $10,990.
