When a larger and more powerful motor is installed on the Razor Dune Buggy the jackshaft can continue to be used for a slight increase in top speed and a major increase in torque and hill climbing ability, or the jackshaft can be removed and the motor can drive the axle directly for a large increase in speed. If the jackshaft is removed and a 500 Watt motor installed then the top speed will be around doubled and the hill climbing ability will be around the same. However if a 1000 Watt motor is installed then the top speed will be around doubled and the hill climbing ability will be twice as good as with the original motor.

Using the Original Jackshaft:

• With 500 Watt motor = same speed and 2 times the hill climbing power
• With 1000 Watt motor = 20% increase in speed and 4 times the hill climbing power.

Deleting the Original Jackshaft (chain goes directly from motor to axle):

• With 500 Watt motor = 2 times increase in speed and same hill climbing power. (Some people have reported that there is not enough torque when running a 500 Watt motor directly to the axle so do this on an experimental basis only.)
• With 1000 Watt motor = 2.2 times increase in speed and 2 times the hill climbing power.

Larger wheels would change the gear ratio and provide a faster top speed however the Razor Dune Buggy has wheels that were made specifically for it and are unique to it, so finding anything other than original wheels for it may prove to be difficult.

Most Razor Dune Buggy modifications do not require welding and metal fabrication, and are done with more common tools such as a drill, hacksaw, etc. Trays to mount the batteries can be made out of Zinc-Plated Steel Slotted Angle or Plywood.

 

In the photo above the motor is mounted to the frame with two 1/4" threaded rods that are bent into a U-shape. This is because if the same motor with mounting base was used it would be too tall to fit into the frame. We recommend placing 1/4" ID clear flexible nylon tubing over the threaded rod where it contacts the motor so the motor's paint does not get scratched and also to provide a better grip onto the motor.

Here are four modification upgrade kits that we currently have for the Razor Dune Buggy:

24 Volt 500 Watt, KIT-24300: https://cart.electricscooterparts.com/24-volt-500-watt-razor-dune-buggy-modification-kit-KIT-24300

24 Volt 500 Watt with Reverse, KIT-24301: https://cart.electricscooterparts.com/24-volt-500-watt-razor-dune-buggy-modification-kit-with-reverse

36 Volt 1000 Watt, KIT-36300: https://cart.electricscooterparts.com/36-volt-1000-watt-razor-dune-buggy-modification-kit

36 Volt 1000 Watt with Reverse, KIT-36301: https://cart.electricscooterparts.com/36-volt-1000-watt-razor-dune-buggy-modification-kit-with-reverse

All of these kits can be customized with different throttles, switches, batteries, chargers, or other parts. If you like one of these kits however would prefer it to have a different part then please let us know and we will make a custom kit tailored specifically for your project.
