Choose the MX400 over the MX350 if your child will ride on anything rougher than flat grass. The suspension makes a real difference on dirt and uneven terrain.
The MX400 sits between the MX350 and MX650 in Razor's lineup. The key upgrade over the MX350 is full front and rear suspension, making it more comfortable on bumpy terrain while keeping the same proven motor and safety record.
Same 14 mph top speed as the MX350. The difference is real: front forks and rear shock absorbers transform the ride quality on dirt paths, grass, and uneven backyards. A noticeable improvement for mixed terrain.
Same 24V 7Ah lead-acid battery as the MX350 — about 30 minutes of ride time. Unchanged and still the weakest aspect of the bike. Overnight charging required.
