The 2015 Suzuki RM-Z450 features new Showa SFF Air Forks and Holeshot Assist.
The Suzuki RM-Z450 takes on a few significant changes for the 2015 model year, such as getting all-new forks and what the company calls its new Suzuki Holeshot Assist Control technology.
Via a switch on the left handlebar, the rider can chose between two modes when using the Holeshot Assist: A-Mode offers a less-aggressive mapping for improved traction and less wheel slip on hard-packed or slippery conditions, while B-Mode provides a more aggressive launch for when conditions offer more traction.
But probably the biggest news is the new fork. The RM-Z450 is now fitted with a Showa SFF Air Fork, which Suzuki claims “delivers more progressive suspension feel and offers infinite adjustability.” The new fork is also 2.5 lighter than the previous SFF spring fork.
Other changes have been made to the RM-Z450’s transmission and starting system.
A lot of effort went into making the new RM-Z450 start easier: It gets a longer kickstart lever, revised kick-gear ratios, updated de-compression system, a redesigned exhaust camshaft and other small changes.
Engine cooling has also been improved. According to Suzuki, the 2015 RM-Z450 has a 16-percent more efficient cooling system. Fluids, they say, travel more effectively between the right and left radiator halves, plus there’s an updated water-pump cover and a revised hose connection directing coolant directly into the water-pump.
Many tweaks have been made to the RM-Z’s frame, so many, in fact, that it’s pretty much all new. Weight has been reduced by four percent, the downtube has been redesigned, and the main frame inner ribs have been reshaped. Suzuki promises better turning and a plusher ride.
Other changes include, updates to the transmission to improve shifting feel and a revised muffler.
Suzuki has not yet announced an MSRP for the 2015 RM-Z450. It will, however, be available to the public in July.
