Given the improvements in range, performance, and capability, the Zero S provides a measurable upgrade in value even as the base price has risen for 2013. The updated Zero S with the 11.4 kWh battery pack runs $15,995, up $2000 from the 2012 model with the ZF9 (9 kWh) pack. The S with the smaller, 8.5 kWh pack costs $13,995, which makes it the same price as last year’s top-line model. Zero DS prices are the same, while the new Zero FX and MX run $9495 to $11,990, depending on battery pack, while the entry-level XU costs $7995 with a 2.8 kWh pack and $10,490 with a 5.7 kWh pack. Something to consider when digesting those prices is that the bikes run for pennies a mile on home electricity, and may benefit from government subsidies. What’s more, all of the Zero models are mechanically uncomplicated, and so should have good reliability and low running costs.
