BUILT FOR THE OPEN CLASS.
The MX450 is ZXMOTO’s 450 class motocross bike, developed alongside the MX250 and built on the same chassis layout. Its 449.9 cc single makes 40 kW and 49 Nm, in a bike that weighs just 105 kg.
TORQUE WHERE YOU NEED IT
Peak torque of 49 Nm arrives at 7,500 rpm, giving the MX450 strong drive out of corners. ECO and Sport riding modes let you choose how that power is delivered to suit the track.
Colour Options
LIGHTWEIGHT, BUILT TO LAST
At 105 kg, the MX450 weighs only 3 kg more than the MX250. A high-strength steel twin-spar frame, aluminium swingarm and one-piece aluminium handlebar keep weight down without giving up the strength a 450 needs.
Performance
Powertrain
A 449.9 cc DOHC single with a 13.5:1 compression ratio, making 40 kW at 9,500 rpm and 49 Nm at 7,500 rpm through a five-speed gearbox.
Racing
All about racing
Power mode adjustment, launch control and lap time recording all come standard, the practical tools a real race day demands, built in rather than bolted on.
Design
Built to Turn Heads and Corners
The MX450 shares the MX250’s aggressive, purposeful lines and 960 mm seat height.
Performance Powertrain
The MX450’s powertrain and chassis are built around the same principle as the MX250: every component earns its place. Here’s what’s underneath it.
Engine
Single-cylinder, DOHC, 4-valve, 4-stroke, 449.9 cc, with a 96 × 62.15 mm bore and stroke, a 13.5:1 compression ratio and fuel injection.
Suspension
KYB front and rear: an inverted fork with fully adjustable damping, and a rear shock with external reservoir and fully adjustable damping.
Braking
Front: a single floating disc with a two-piston caliper. Rear: a single disc with a monobloc caliper.
Frame
A high-strength steel twin-spar frame, paired with an aluminium alloy double-sided swingarm and a one-piece aluminium alloy handlebar.
Keyless Ignition
Keyless ignition comes standard, so there's one less thing to carry on race day.
Swingarm
Lightweight aluminium swingarm and premium 7075 aluminium wheel rims enhance handling, strength, and durability.
Core Configuration
A 1483 mm wheelbase, 28-degree rake and 42-degree steering angle give the MX450 stable, predictable geometry.
Practical
A high-strength one-piece aluminium alloy handlebar sets your control point, with keyless ignition for a quick start.
Fuel tank
A 6.5-litre fuel tank, the same capacity as the MX250.
Exhaust
A stainless steel exhaust pipe paired with an aluminium alloy muffler shell, built for durability without unnecessary weight.
Wheels
Spoked wheels with cast aluminium hubs, 21-inch front and 19-inch rear, fitted with CST tyres.
Quality
KYB suspension front and rear, CST tyres and a wet multi-plate hydraulic slipper clutch. Proven componentry, properly specified for racing.
