NEW RM-Z450 GETS SERIOUS
Suzuki RM-Z450 gets new chassis, updated engine and traction control
It’s not even the height of summer but, as is usual in the off-road world, manufacturers are already unveiling their fresh temptations for 2018. So here’s Suzuki’s new RM-Z450 – boasting a rush of changes to bring it bang up to date.
The biggest change is the all-new chassis, which Suzuki say has lost 700g while remaining just as rigid. The swingarm has followed suit, shedding 100g, while the subframe has a new structure that enables it to be slimmer and to mount the new Showa Balance Free shock. With the changes in the suspension, the wheelbase has been reduced by 15mm which, combined with the weight savings, should improve agility.
There have been some changes in the engine too, including smoother porting, bigger intakes and a new cam profile, which Suzuki say have given the 450 a stronger midrange and smoother throttle response.
Despite their dirty intentions, the latest motocross bikes are often packed to the rafters with clever electronics and the 450 is no different, gaining a new version of Suzuki’s Holeshot Assist system. Holding down a button on the handlebars selects either A or B mode, which either advances or retards the ignition timing for race starts – depending on the amount of grip available. After six seconds of riding, the map returns to normal but continues to monitor the throttle position to match the riding conditions.
The new model arrives in dealers this Autumn, with the price to be confirmed. The current model costs £6599.
