Suzuki Motor of America Press Release:

Suzuki Motor of America introduces the new 2015 Suzuki RM-Z450, engineered with new race-proven features to boost riding and racing performance from the gate drop to the checkered flag. Suzuki also announces the return of the Suzuki RM85 for 2015, as well as the Suzuki RM-Z250.

The new 2015 RM-Z450 (Price TBD) leads the field with new features and targeted improvements developed through worldwide race testing to provide even stronger racing performance. With its new Suzuki Holeshot Assist Control technology, the RM-Z450 gives racers a distinct advantage every time the gate drops, no matter the surface. By selecting the Holeshot Assist Control’s A Mode, RM-Z450 riders will have enhanced traction and less wheel slip on hard-packed or slippery conditions.

In B Mode, the RM-Z450 provides a more aggressive launch when gate conditions provide more traction. In either mode, Suzuki Holeshot Assist Control is programmed with specific commands that return ignition timing to normal operation and let riders power into and through the first turn. Riders engage Suzuki Holeshot Assist Control from a button on the left-side handlebar, and can shut the system off, too.

To help riders with control of track and trail beyond the starting gate, the new RM-Z450 features the Showa SFF Air Fork. Tested and proven by factory racers including James Stewart, the SFF-Air is now standard on the 2015 RM-Z450, and delivers more progressive suspension feel and offers infinite adjustability in a package that’s nearly 2.5 pounds lighter than the conventional spring fork. Adjustments to the SFF-Air fork can be made easily with use of a hand-held pump.

Suzuki engineers redesigned a number of components – including a longer kickstart lever, revised kick-gear ratios, updated de-compression system, a redesigned exhaust camshaft and more – to make the 2015 RM-Z450 easier to start, saving time and energy for riding.

This new RM-Z450 features a 16-percent more efficient cooling system, with fluids traveling more effectively between right and left radiator halves, plus an updated water-pump cover and revised hose connection directing coolant directly into the water-pump.

With its mission of continuing to deliver “the winning balance,” the RM-Z450 received several more improvements for 2015:

- Precision gear matching for improved shifting feel,

- Revised exhaust muffler to meet strict AMA sound regulations,

- Redesigned frame members for a 4-percent weight reduction and balanced rigidity.

The RM-Z450 still features key components such as Suzuki Fuel Injection with two additional plug-in fuel couplers feeding a 449cc liquid-cooled four-stroke engine with dual overhead cams, as well as the comfort, confidence and control of Renthal FatBars, Excel aluminum rims, and waved disc rotors.

2015 RM-Z450 Final Testing:

The complete line of 2015 Suzuki RM-Z and RM motorcycles will be available at Suzuki dealers beginning in July and will all be eligible for Suzuki contingency.
