adjustment at the front , with the rear monoshock having 130mm travel and preload adjustment . Hauling on the stoppers activates a radially mounted four-piston ByBre ( ByBrembo ) caliper which bites down on a 320mm disc , and at the rear the ByBre caliper clamps onto a 220mm disc . As you ’ d expect , ABS is standard with the dual channel system able to be switched between activating on both wheels or just the front . Rolling stock comes in the form of 17-inch rims with a 110 / 70 tyre at the front and 150 / 60 at the rear . Aprilia reckons this is the perfect combo for excellent grip while maintaining agility . Aprilia is known for being at the forefront of the tech race , and the RS457 doesn ’ t disappoint in that regard . Keeping the rider informed is a 5-inch TFT dash , while the lighting is all LED . The switchgear is also back-lit which will be a welcome addition for the learner market the bike is intended for . While seat height has yet to be announced by Aprilia , it ’ s looking like the RS457 is going to be an approachable machine as well as a tonne of fun . Currently , Aprilia NZ expects the RS457 to arrive in mid-2024 with pricing expected to be competitive with Kawasaki ’ s Ninja 400 .
